POLL: 400w HPS *or* 1000w MH for flowering, what would you use?
    #339372 - 01/03/10 12:51 PM (6 years, 10 months ago)

i have a 1000w MH and a digital 400w (which is either or)
any how i want to make the most of what i got and i would like to ask
peeps with some experiance which lamp you would use for flowering, for the fattest yields and best quality if you only had these two options .
also would you please descibe the differences, if any, between flowering w/ MH vs. HPS

The HPS are always better for flowering than a MH, you should use the 400W HPS now

Depends on the size of the grow area.  A 400 watt light in a small space is a lot easier to keep cool then a 1k light.  At the very least you should follow the 50 watt rule.  For every square foot in the grow room, you want 50 watts of your power dedicated to it.

IE

3x2 room = 6 square feet
400 watts / 6 ft sq = 66.67 watts per sq ft

So a 400 watt lamp would put off enough light to adequately support a 3x2 grow room.  Now, if you have the ability to keep your grow area cool enough to use the 1k MH lamp, go for it.  I'd personally use the HPS because I'd want the correct spectrum over more lumens, but that's just me.

Well, is it possible for you to run both lights??  That's the way I would go.

coda- what is the reason for the HPS preferance?
BTW those are my exact room dimentions (you looked at the pic, didnt you)

hawk- the 1k lamp in the space is so fucking hot that i can bearly keep the temps below 85 degrees.............i think im gonna reinstate the 400wt .........




will that fuck my plants up?

HPS = Larger, more airy buds

MH = Smaller, compact and dense

I myself prefer dense nugs and would use the MH, but if you can handle the wattage and power use I would DEFINITELY use both, as you will obviously get the best of both worlds if you do.

If you are selling it all, then use the HPS because you may get larger looking buds, which seem to sell better?  :shrug:

What are you basing this on??  Wattage?? 

Because HPS does NOT cause larger more airy nugs.  A less amount of watts/lumens might.

To answer your question marr.

HPS is the preferred lighting for flowering because of the spectrum of light that it puts off.  HPS replicates the orange/red end of the light spectrum, similar to end of summer/fall light.  Where MH gives off a blue/white light end of the spectrum.


Switching the light shouldn't cause any problems with your plants.


I take it you don't have vented hoods??  Bummer, your plants would much prefer to have both of those in there. 


If I had to pick one over the other I would go with the HPS. MH sucks for flowering.

wow werid, wasn't able to post in this forum last night for some odd reason.

Anyhow, Hawk has it right.  HPS puts out the proper spectrum for your plants to use during the flowering cycle.  You're much better off using an HPS for flowering then a MH, but if you only have an MH it will work in a pinch.

Inverted, I don't know where you heard this thing about airy buds from HPS lamps but it's just not true.  Take a look at any of Mag's buds, IIRC he's strictly HPS with flowering.  I wouldn't call any of those nugs airy :wink:

i ve had problems trying to post in here several times............
update- i now have a 1k HPS, thank you guys for all the feed back.
this is my first gro indoors and all the help i can get is mucho appreciated...............coda- i got the clone set up now thank you so much for the info , i wished i wasn t so pissed when i named the thread because i m sure it would be of great help/intrest to those who are just getting started....short,sweet and simple to the point effective, results..........
one question for you guys.........back in '99/'00 i took a trip to N. cali with some friends and we took a 1/4# of kill from north seattle area with us...........big fluffy buds, sweet strong flavor esp when lit whith a magnifying glass. but the thing i remember the most was the smell. we put that shit inside 2 boxes and underneath all our shit packed into the back of the van and the smell was still strong and penetrated the whole van FOR THE WHOLE TRIP!!! it never lost its potent smell and i ve never come across bud with such a strong smell since. can you experienced growers please tell me what kind of strains do this............... i smoke alot of good herb but not really ever any really GOOD aroma in a long time..........

it was so hot in there i couldn't keep it below 90 with the doors wide open!!!!
instant fixer, now im a nice even 80 w/85+ being the high when i close the doors (closet doors, small space) talk about a load off, these poor babies were living a life of constant stress................

Actually I stand my ground.  I've read hundreds if not thousands of grow journals and from many of the PROS at ICmag, that is EXACTLY WHAT THEY TOLD ME.

I'm going to believe someone who has been doing it for 20-30 years, using BOTH to grow crops.

Not being an ass or anything, but I have seen the results...  A combination of both is optimal, along with some UVB fluorescents for added trich production.

I'm sorry man but I've just read that statement far too many times to disregard that many professional growers.  Magash is one of thousands.

What are you basing your theories off of?  You've only seen some pictures, or maybe sampled a little bud.  I'm not saying you cannot get dense buds from an HPS, but from all of the research I have come across, MH is TOTALLY FINE for flowering, it will just produce smaller more compact buds, while HPS will be larger, but slightly less dense, and combining the two is the best.  It is more strain dependent than anything!  I only have 150w HPS and am using 200w of CFL's alongside that, and 2 of my plants have some of the densest buds I've ever created.  But I cannot be 100% sure until they are dried and cured.

Where did I say it wasn't?  I just don't buy into the HPS produces airy buds line.  That's all.
