Lets build a grow room!
    #132776 - 10/15/08 06:09 PM (13 years, 9 days ago)

Hey everyone!
I'm in the process of converting an old, unused, wasted attic into something productive - a grow space!

What I need from all of you is help / insight / recommendations / criticism (constructive or not).  Here is a model of my attic, semi-to scale (the dimensions are right, but the ratios are not):













So, what am thinking of doing is:
  • Since the ceilings are kind of low (7' at the peak), and the slope of the walls is pretty steep, I can't use the entire width of the attic.
  • So, hang the grow lights sideways (that is, going the width, not the length, of the attic), with tables underneath, running the same way.
  • This will give me access to walk down either side of the tables / lights, and give the plants a few feet (up to 5 or 6, though 4 would probably suffice) to grow.
  • Next, separate the attic into different segments - one for cloning / seedlings / the mother, one for veg, and one for flowering.
  • There are 9 segments (separated by a wooden stud - check out the picture), so I am thinking maybe, 2 segments for each, leaving 2 segments at the beginning and 1 at the end.
  • Each segment will have the appropriate light hanging overhead, with the table underneath.
  • As for ventilation, there are already two exhaust fans in the roof that I could use - simply add a carbon scrubber (which I will construct myself).


So, this is where I am so far.  What do you all think?
I am going to start with soil, to get the hang of it, and them move on to hydroponics.


Actually, the floor is only half done, so would now be a good time to run piping around, for easy distribution of the water?

What wattage lighting would be sufficient, for the area covered?  400w or 600w?

And for insulation - since this is an attic, do you think that the reflective-type insulation would work, for keeping helicopters at bay?  It is basically two pieces of aluminum foil, with dead air space in between.  I still plan on lining the rooms with mylar.

Thanks!

Couple problems I see:
  Do you live in a cold climate? If snow melts off your roof, it looks odd to LEO. Insulate the hell out of the ceiling, think Styrofoam-board, fiberglass, Styrofoam-board sandwich, all covered with black/white poly film or mylar. This will also be helpful in the summer months to keep heat at bay.

    The fans in the attic are most likely not going to suffice for ventilation, especially in warm weather. You will have to get some good inline fans, especially if you plan on using a carbon scrubber.

    How much height will you have on the sides to walk in? Crawling into each segment of the grow will get old really fast.

    Are you going to build the tables in the attic? Do you have enough room to get lumber and other larger items through the little crawl space door?

    Mylar is not a great floor cover, it is generally very thin (1-3 mil) and prone to tearing. Black and white poly may be a better option.



Things I like:
    Good thinking on the water issue, installing some sort of rudimentary plumbing will save you a world of hurt when you are crawling supplies into and out of your room.

    You are thinking about coverage. A 400w lamp will illuminate a 4'x4' area. Simple math tells me each segment is ~4'. So in your flowering section, two 400w lights hung above two tables will work great. In your veg section two 400w lamps might be overkill but with a stud in the center your going to have to use two lamps, two 250w mh lights would be best I would say. In the mother room, 2-3 4' shop light floro tubes would work great.



Other things of note:
    Make sure you evaluate and perhaps run new electrical lines to the rooms, fires suck. You can do this easily now while the floor is unfinished.

    If you use the system I've described with dual lights in each section, you can run a staggered harvest in which a new batch of plants are introduced into flower each month. That will leave one month veg and two month flower time for your girls and you will only have to harvest half the plants each month.

   

I think thats about all I have for now. Keep us posted on your progress!

Hey, and thank you for the reply.
It gets pretty cold during the winter, but we do not get much snow...  I hear you though, and didn't think of that (the snow melting), so properly insulating the attic is definitely even that more important.

So what is recommended, then?  Use squirrel-fans (whatever they're called), connected to duct work, that just pipes to the outside of the house?

Height is definitely an issue.  I will have to double check / remeasure the area so that I will be sure that I won't be crawling / hunching around.  Any other recommendations on how to lay the tables / plants out, if height isn't permitting me to stand?

Yup, I plan on buying wood and assembling the tables in the attic.  Should be plenty of space - you'd be surprised to see what was in there before I cleaned it out. :smile:

Alright on the Mylar - thanks for the heads up.


So you do recommend using 400w lamps, eh?  Good.  Less heat to worry about, compared to a 600w.  400w'ers in the veg section would be overkill?  How so?  Always thought that the more light, the better.


We have a new, 200amp breaker box downstairs, and I've bought some 10awg wire and a 30amp breaker to dedicate to the attic.  I think 30amp should be enough for whatever I throw up there (I'll do calculations anyway, don't worry!)


Thanks again for the tips!


Here is my current progress / setup, while I am fixing up the attic...


:frown:

No need for the sad face! Squirrel cage blowers will work just fine but I recommend 'centrifugal inline fans' vortex, can-fan, or something along those lines. They are much easier to work with, no need for adapters on the outlet side or anything; plus if you decide to go with air cooled lights at some point, they are much easier to attach to that system.

For height, you can build a two tiered table with the light hung parallel to the wall shining at the tiers. On the first row you place your oldest plants, the top, your newest (for a slightly sloped canopy). When you harvest the bottom plants, move the top plants down and place a set from veg into flower on the top shelf. This way you could extend the tables only 1' past the mid way point and be able to walk around the back sides of them. If you don't understand what I'm talking about, think stadium seating.

As far as light goes, if you can afford it, up the size of the lights. Like you said the more light the better! (As long as you can keep them cool.)

Heat is going to be a big concern I believe. Unless you live in the tundra, the sun beating down on that roof during summer is going to be brutal. You might even have to think about air conditioning. Any idea how hot it gets in there?

Make sure you set yourself a reasonable time budget. This is a big project you are undertaking. Unless you work your ass off, those seedlings are going to need a home before you're finished. Just be aware.

Anyway, I think you're on a great track, don't let me discourage you! If this all pans out you will have a very productive use of a formerly wasted space. Post pics of any more work you get done!

Thanks for the recommendation on the lights / fans.  With heat becoming a definite issue during the summer, I had as might as well invest in the air cooled lights right now.  More research to do!  Summer heat really is ridiculous and I know that it gets well over 100f in there.  At least, with winter coming, heat won't be that extreme for a little while.

Awesome idea for the height - exactly why I asked. :smile:

The difference in cost between a 400w and 600w light / ballast isn't that much, so I'll probably just go with the 600w.  Or did you mean up from 250w to 400w?

This definitely is a huge project, so I do expect to have to take care of these plants before it is finished.  I am cleaning out my closet (formerly a mushroom cultivation area) so that I can fully convert it into a small-scare marijuana-machine, for the time being.

Oh my god man! Those mushrooms look like the could fucking eat me!

If the temps in there get above 100f in the summer you are going to be hurting to keep the plants healthy especially with lights up there. You are defintly going to have to think about air conditioning. If you buy air cooled lights you can run them in a sealed loop, ie: they pull fresh air in from one hole, go through the lights, and back out the other hole without taking in any of the grow room air. If you go that route you will still need to exhaust the room air through a third hole unless you want to use CO2 in a sealed room, but thats a whole nother can of worms. Anyway, keep me posted!

Hey! Welcome here, let's build this room :laugh:!

Temperature will be your main concern in this attic (as you and Penguin already noted), unless you live in a very moderate climate. This sun on the roof will create high temperatures. Thermal-isolate the ceiling if you can! Isolation and a good fan that sucks colder air will do the trick with 400-800W in there. I don't think you should be worried about helicopters with ~600W, mylar and thermal isolation.

Not if you have an active inlet fan that brings cold air from a cold or air-cooled room. You de need colder air though. 

600W is good. Go with 2x 400W if you want to cover a large wide space. Any dimensions in mind for the actual grow/flower area?

Do the piping if you can. It's always handy to have water close to your room.

Yes, this kind works great:

    #134788 - 10/20/08 06:37 PM (13 years, 4 days ago)

Since we are going into the winter, I have a few months until I have to worry about summer heat.  I plan on spending a lot of money on insulation and ventilation...  And lighting...  Thinking about buying my first 600w HPS with a digital ballast this Friday!

The room conversion is coming along slowly, but steadily.  In the mean time, my seedlings are still growing:

I have been watering them every 1 or 2 days, depending on how dry the soil looks.  Using 2x 23w CFLs right now, about 5" from the plants.

No fertilizers so far, either.  Been to 3 shops around here, and none of them are carrying any supplies (out of season).  What specifically should I be looking for?  If I want to water them with a solution of X-Y-Z, how do I do that?  What do I need to add to the water to reach certain levels / how do I measure it?

Sorry for sounding so noobish about the fertilizers.  I have read numerous grow guides, but they always simply say "during rooting / germination, water with a solution of X-Y-Z" - they do not say how to get that solution!

Thanks!


Edit:  Also, where is a good place to buy the ventilation supplies?  Home Depot / Lowes?

Your plants are looking good. :thumbup:
Be careful when judging when to water by eye, it is easy to over water like that because the lights dry out the top of the soil but it may be retaining plenty of moisture at the bottom of the pot. The best way to evaluate when to water is weight. Get to know what a dry cup of soil feels like, when your plants get to about that point, give them some water. For example, I have some seedlings in the exact same cups as yours and I only water every 3-4 days.

The best way to get x-y-z is to either use a three part hydroponic fertilizer, or to use a fert that has the ratios you want already. Getting an exact N-P-K ratio isn't all that important, as long as they are close. I am mainly a hydro grower so I use GH FloraNova but when I do use soil I use the Earth Juice line to good effect. I hear great things about Fox Farm nutes as well, just mix them according to the label and away you go.

The best place to get all of these things is a local hydroponics store. They will carry HID lighting supplies, proper nutes, and inline fans. The type of ferts and fans you will get at home depot are generally very sub-par in this hobby. You can also use the internet to find great deals on supplies, but remember to use a money order or a pre-paid gift card and to ship to a location other than your grow house.

Took your advice on this one.  I let the plants go 4 days without water, got their feel for weight, and am now watering when they feel dry by weight.  Good idea!

I found a local hydroponics shop and I am going to swing by there after work (in about 2 hours).
I plan on looking at their light selection.  I am definitely going to buy some of the nutrients, and also look at their lights and fans.  I would _like_ to leave with a 600w HPS bulb, a good reflector, a digital ballast, and an inline fan, but that all depends on cost. :wink:
I'll post a picture of my plants soon.  One is looking great, the other, not so much.

Pics will be up later.  Construction is so fun! :thumbup:

I kind of accidentally knocked my plants off their shelf and onto the floor yesterday...  They both came out of the cups and any lose soil (soil that has not been rooted) came out.

So now is a good time to transplant.  Which size cups / pots should I upgrade to?

Bought my lighting system this weekend from the local hydro shop, and the prices were very good (compared to a few online sites).  Bought a 600w HPS, a cooltube reflector, and a 600w digital switchable ballast.  Also purchased nutrients!

Yesterday, replanted into a 1gal pot, watered with the nutrients, and set them up under the new light.  Checked on them this morning - the ambient room temperature was around 56f, and the temperature at the top of the pot / soil was 70f.  Mid-day, the temperature of the pot should reach around 80f, though I am going to use a space heater to keep the ambient temperature higher.

My digital camera ran out of batteries, so I do not have any construction pictures, though here is one of my current setup (ghetto, I know - but a work in progress):



Maybe this thread should be moved to the Grow Log forum?

So, I pretty much hate my cooltube.  Not only does the output seem to be low, but the plant on the end of the tube that is further away from the light (in the above picture, the right plant) hardly gets any coverage.

Also, the reflector batwings don't seem to fit together.  Any insight?

The holes do not line up.  I could just drill a new one...


I am going to take the reflector back and see if I can trade it in...  Probably going to go with a standard rectangle one.

Edit:  Also, I am currently running the lights 24/7.  Should I give them a few hours of darkness yet?

just work with you got (unless you could afford more). good job on the hydro store :thumbup: my local one seems to beat any internet price by far.


there is a post here about the difference between 24/0 and 16/8. 24/0 pwnd. the only thing i've been thinking about lately is the fact that it must be strange to the plant to go form 24/0 to 12/12 in one night. im thinking about slowly decreasing the time. peace out and good luck

Sorry to hear about your cool tube. I have never used a commercial tube, only home made. The bulb should be centered in the glass and therefore the reflector, also the edges should fit correctly. Sounds like you got a lemon. I would definitely try to return it, most hydro shops will be glad to hear about your experiences (good or bad) with one of their products. If they have a better cool tube model, you could try that, or if not you can try an air cooled traditional reflector. Let us know what happens!

Day 17 [Re: Dr. Penguin]
    #138692 - 10/30/08 08:25 PM (12 years, 11 months ago)

Well I managed to get the reflector on - I just drilled a hole through the two pieces and fastened them together.

So, two things:

1, my plants are not looking good.  They are turning yellow and the tips are turning brown / yellow.  I have only fertilized them once, and that was when I transplanted them to the larger pots.  Since then, I have give them one more watering, which did not have any fertilizers in it.



2, This is one of the exhaust fans in my attic...  Any tips on rigging up some ducting to connect to this?  Smell is starting to become an issue, so I need to figure this out quickly.


Thanks!

It's hard to diagnose problems like this. First I would check the Ph of the runoff and make sure its at the proper levels (5.8-6.8). If they are, then I would have to guess immobile micro-nutrient deficiency (Manganese?). What type of fert are you using?

There is no runoff...  I guess I am not watering enough?
I can not remember the name of the ferts (Tiger Something) - I will write them down in the morning when I check on my plants.

Could the HPS have been too close, burning the plants?  The area isn't that hot, but I am wondering if there is just too much light, or if they do need some dark-time.

Anyone else want to chime in about the exhaust fan? :-D

Marijuana is a C4 plant which doesn't require a dark period, 24/0 will provide the fastest growth. Those really don't look like light burns to me. Light burns are usually much bigger and result in bleaching of the leaves. Next time you water, water them until water runs out the bottom of the pots. Check the Ph of this runoff with a digital Ph meter or litmus strips and let us know what the Ph is.

As for the exhaust fan, you can buy 8" (it looks like 8" I'm not sure) flange fittings at home depot. Grab some caulk, seal the edges, screw down the flange and attach ducting. But that fan will not be strong enough to provide the ventilation you will need. That kind of fan cannot be connected to a carbon scrubber so as soon as full flower comes on, you are going to have some stink outside your house. Be careful.

OK,

PH of water before watering - ~6.5
PH of runoff of the smaller plant - ~6.0
PH of runoff of the larger plant - ~5.0

Sounds like your Ph might be a bit low. You can water with a touch of hydrated lime if you'd like. Hydrated lime is a quick fix, it will raise the Ph for about a week or so. Next time you transplant, add a bit of quick lime or garden lime to the mix, that should buffer your soil to about where you need it. If fixing the Ph doesn't solve your problem, we can try something else. Good luck!

P.S. Any word on the type of fert you are using?

OK, so, lime is used to raise PH?  (You said "lower the Ph for about a week").  I added worm castings, garden gypsum, bone meal and vermiculite to the soil when I transplanted - could it have been too much of this stuff (the first 3, I suppose)?

I am using Foxfarm Grow Big (6-4-4) and Tiger Bloom (2-8-4).  When i transplanted, I used both.  During the last watering, I used only the former.

Also, could it be heat?  The sensor in the pot was reading 90 when I just checked up there.

I need to go out and buy some of those pitpot things so that I can germinate new seeds...  I hate putting them from the shot glass, right into a solo cup.

Raise the Ph, sorry. (Post edited).  Those are good nutes, they shouldn't be causing any sort of micro nutrient deficiencies. With temperatures above 90o it could definitely be heat stress. Try fixing the Ph and lowering the temperatures, that should fix you up. Let me know what happens.

Heat has been corrected and I have begun foliar feeding with straight-up PH-corrected (used vinegar and baking soda) filtered water and the leaves are still quite yellow.  The plants are definitely growing, and the smell is ridiculous, but yellow.

Either today or tomorrow I will be watering the plants, the first time with the PH adjusted water.

I am also considering buying a 600w MH light to use in place of the HPS, until I begin budding.

Will follow up soon!

OK.

Went to the hydro store yesterday, bought PH up an down, and a 600w MH blue-tinted light (to replace the HPS light).  Only digital PH meeters that they had are above $100...  Screw that, I'll use my drops and vial.

Came home, swapped the light, corrected the PH of the water, watered, and tested run off.  Runoff was a little low (6.0ish).

Been a little over 24 hours since.  Just checked on them and WOW.  Not only are the leaves returning to a green color, but the plant has grown at least an inch.

I'll give it a few more days (or at least until the next watering), and hopefully the leaves will be back to their dark-green coluor.

Thanks for the help!

Hows the construction coming? Lets see some pics. :thumbup:

The plants are really growing.  Like whoa.  The watt / square-foot ratio is very high.

Construction is on hold...

I'll have to take some pictures of the plants - still some yellowing going on.

Day 28 [Re: Dr. Penguin]
    #142731 - 11/09/08 12:42 PM (12 years, 11 months ago)

Here be the pictures!


















How do these look for day 28?  These have been on 24/0 with a 600w HPS, and just recently a MH.
As you can see, some of the leaves are quiet yellow...  Wondering if I should just snip them off, or let them go?  Why aren't they re-greening like the rest of the leaves?
Should the light be closer or further?

Some leaves will just never regreen. I usually cut my damaged leaves off when they are 3/4 dead. I would take off a couple of your bottoms leaves but the plants look pretty robust. Also, I would think about flushing the pots out really well, the tips of the new growth is still yellow. If you flush it, use the ferts as directed, and the ph up/down only when required, I think they will fully green up in no time. Good luck.

What's the distance between the tops and the light? The leaves look like it may be a bit too hot.

Don't worry about the old leaves. You can just let them go. They will not recover. It's important that new leaves stay healthy.

So how exactly do I flush?  With water, I assume.  I guess flushing is giving them enough water that the runoff is just flowing out?

Yup, you flush with water. I usually do ~ 3-4 times the volume of the pot. So if I have them in 1gal pots, use 3-4 gal water. Or you can put them in the sink/tub and turn the water on to a trickle and let it run through the soil for about a half hour.

I like your new avatar, Doctor. :smile:

So, I flushed the soil yesterday and man did I make a mess.  I figured that the plants would be in horrible condition today...  Man am I wrong!  They are dark green and flourishing!  Amazing.  Last time I am going to do a soil grow...  Can't wait to do hydro!

So with my next watering, I will reintroduce the fertilizers, though only at 75% or so.  Should I add ferts to my foliar feeding?

Today is the 1-month mark of my plants.  I wonder how much longer I will keep them on 24/0 lighting, before switching to budding...  Wonder if I want to mess with a mother / clones as well...

Temperature is becoming more of an issue (or not).  The ambient temperature up there is around 55, and the temperature around the pots is around 60...  Regardless, the plants seem to be growing just fine.

Thanks, I like it too. Much better than the shitty photoshop one I had.

Yup, I usually don't mess with soil because its a mess and a pain in the ass. I'm glad to hear the flush went well for ya though. I thought it would help.

I personally never foliar feed. Leaves are for light, roots are for nutes in my opinion. The only time I ever spray my leaves is when I get an immobile element deficiency. Otherwise there are just too many things that could hurt more than help.

I vote for trying clones. They save so much time and effort in the long run. No guessing about sex, you know exactly what they like and don't like, constant yield, and all the plants are all uniform in size/growth pattern (a huge help later for you when you want to set up your tiers.)

Those temps are very low, I'd be worried about it personally. Growth rate is directly proportional to tempearature (up to a point ~85F). So the warmer it is, they faster you see results. A little space heater with a themostat would be a wise investment.

Keep up the good work and picture posting!

Day 31 [Re: Dr. Penguin]
    #144905 - 11/14/08 09:43 PM (12 years, 11 months ago)

Linux user, by any chance?

Now that the plants are over a month old, should I just get some of those little rockwoll cubes, clip off a cuttling, and try cloning with the hormone stuff?

Also, smell is becoming a huge problem.  If I go and build a carbon scrubber, are there any other types of (cheaper) fans that I could use?  6" inline fans cost a whole lot of money...

I put a small space heater up there and set the thermostat to 80f - lets see what happens next!

GrowPuppet:
Happy to help, be it inadvertently or not. :smile:


And now pictures of day 31 (Two pictures of each plant):









Do they look big, small, fat, skinny?  Just want to know how they look for day 31...

Another thing that just came to mind...  How could I turn this into a screen of green (SCROG?) grow?  If one of these turns out to be male, the other female, I would scrog the male, and mother the female.

Looking great!

Cloning is simple, take a cutting two or three nodes from the top of a side branch. Stick it in a rockwool or rapid rooter cube with rooting gel or powder. Wait and voila, clone.

The only cheap way to be able to achieve the static pressure needed by a carbon scrubber is a squirrel cage blower. If you go to a HVAC store and ask for a used furnace blower, you will be able to get one pretty cheaply. Just make sure to get one with enough cfm to exchange the air in the room a minimum of 1 time per 5 minutes.

I'm glad you decided to use the heater, It will defintly speed up growth. For the temp, I would move it doen about 5 degrees to 75F, which is about the maximum temp for optimal growth.

I wouldn't use a scrog screen without using clones personally. If one of your plants turns out to be male, you will be left with a huge hole in you canopy wasting space, contrary to the main goal of the scrog. If you go clones next run then I would defintly try it out, it can be a huge difference.

Going to try out cloning today!  My plants are large enough that I want to start budding them...

Do I need the cubes, or could I use another solo cup with vermiculite?


EDIT:  I'll just buy the cubes, but not until I get a hydroponics system figured out for my cloning and for my mother.  Need to do it soon!  And on the cheap.

Flood and drain for the Mother. Easy to make and build fairly cheaply.

For the cloning check out the ez clone thread and just make one of those yourself. Can also be done fairly cheaply and easily.

Growing in this area is too much of a pain.  I am going to make a clone for a friend, but am just going to finish this grow out until I have better facilities.

Here be how things are currently looking:


This is the plant on the right:


And the plant on the left:



It looks like the left plant is a male, and the right plant is a female, right?

Thanks man.  It is not that I want to scrap the grow, but that the space in mind (the attic), is no longer an option.  I do have a spare closet (the one that I used for my mushroomery), though the size (5.29' L x 3.29' W x ~9' H) seems less suited for this type of a grow.  What do you think?  I actually have _a lot_ of time on my hands, right now!  Of course, I would go with hydro this time around, but I am not sure if I have the space for a clone / mother section and a fruiting section, which is what I would like to do.

The leaves look toasted?  All of the new leaves (just about any since my last complaint about brown leaves) are a nice dark green, with the occasional yellow leaf tip.  There are a bunch of preflowers - they showed up pretty early on.  The plant is practically covered in buds.


I didn't want to ask this early on, but, any estimate on dry yield?  This was taken on the same day as the above bud image.

The strain is White Widow.

Anyway, the plant almost died.  I checked on it today and the temperature was 42F - the heater had died from, I suppose, being on 24/7 for the last month.  Put a better space heater up there, on a 4-hour on, 15-minute off cycle, and hopefully that will save it...

I am about to move the plant from the attic, to a closet.  Since the closet is so small, I can not bring the light, or heat would become an issue - I will now be using two 43w CFLs, in a 12 / 12 schedule.
I know that this isn't ideal, but it is better than having a dead plant!

OK, she has been brought inside.  Her sleep cycle was disrupted for about 30 minutes, but for now on, she should be on 12 / 12 again.

She is not looking very pretty... Some of the sun leaves are wilting, etc.  Any tips on bringing her back on strong?  Should I keep up with the ferts, or just give her straight water?

Sorry to hear about your dilemma. I would hit her with some straight water and let her bounce back. If you have anything with B vitamins in it (Thrive alive Green or others), that may help as well.

As far as changing the light goes, I think you will be disappointed. I would deal with the heat problems by buying a cabinet or building a wooden box, but switching to 84w of light will be a great shock to the plant and a waste of potential bud.

Man are you right!  I have seen nearly zero growth since changing over the lights.
It is cold enough here now that I can open a window, put in a window fan, suck in cold air, and leave the door to the closet open (with another fan, sucking in), and the temperature stays around 90F, with the 600w HPS.

So after a quick question in the Doctor's Diagnosis forum, I decided to harvest my plant.  It is late so I won't go into how much I learned, what I will do differently next time, or how much this site helped me:


Not looking very happy. :frown:

A very  nice close-up.

I do have one question.  Can I do anything (such as hash, etc) with all of the leaves and clippings?

I am going to let this stuff dry out for about two weeks, smoke some, and then cure the rest for two weeks.  I will update then with how it smokes!

Nice thread!  You can make cannabutter with your trimmings:thumbup:  How did it end up turning out?  Pretty good?  Are you going to cure it?  I'm kind of confused, were you flowering under a MH?

I haven't smoked any of it yet - going to wait at least two weeks before I smoke any, and then I will cure it for another two.  So a good month before I start smoking most of this.  I was flowering under a 600w HPS.
