Hey need a little help to get started (lighting)
    #364842 - 02/15/10 07:05 PM (6 years, 9 months ago)

Hey I'm new here could you help me out.

I'm planing on growing one plant at a time
at the moment i have a frame set up with mirror's mounted inwards basically a box made of mirrors .
it is 2ft x 2ft and is 6 foot high and is solid
i have a fan built in the top sucking the air out and a hole at the bottom letting air flow in.
i was just wondering what type of lighting i would need
iv done allot of reading around and found that i should have a "red" and a  "blue" spec bulb and have both of them on for 24 hours until flowering when i should turn the blue of and cut the light to 12 hours is this right and should i get these bulbs

45w Blue Spectrum 6400k CFL grow light
45w Red Spectrum 2700k CFL grow lamp bulb

They are the energy saving ones by the way.

this is my first grow so i don't want to go over board and get loads of equipment straight away ,after my first grow i will invest more into the secound grow if you no what i mean

many thanks in advanced all tip welcome.
Rob

The 6500k(Blue) will be used for the 24hr period. the other 2700k(Red) is used for flowering and will need to be on a 12/12 light cycle to initiate flowering.

Mirrors aren't nearly as efficent at reflecting light as you would think, Mylar or white paint would serve you better.

The best advice I can give you is to consider each aspect of the grow and search a few different words for each.. As in: Lights, Nutrients, Growing medium, Growing method, Odor control etc. Take your time, read the threads, establish who is speaking from experience and listen to them.

There is a wealth of information on this forum and if you take the time to go over it, pay attention, you'll find that everything you need to know is already here and you can save yourself time in not waiting for people to respond.

I am confident in saying that damn near anyone who gets on this site and does their homework can pull of a succesful grow.

ok i now have a set up with one miror and the rest painted white i have a fan in the top sucking the air out like the previous ill upload some pictures soon but now i only have a 1.2ft x 1.3ft space i only want one plant so this should be surfishant space.
what is the total watts i would need for this area and if a bulb says 45w equal to 225w what would i get the measure from 225 or 45

having trouble geting the photos up but ill try again later or tomorow

I'm not sure I've ever seen 45 watt CFLs, however as many of those as you can fit in your grow area and still keep temperatures reasonable would be best. I'd suggest going for 4 of those, perhaps 2 of each spectrum, and use all 4 at all times. Remember those bulbs need to be within 2-3 inches of your plants to be effective. The closer they are, the better.

You didn't mention whether or not the height change when you revised your setup, however 6' is more than you'll need for a single CFL grow. You could reasonably divide that height into two separate chambers and have a veg/clone/mother chamber and a flowering chamber, but keeping the lighting separate will present some challenges.

hey going by the post above i think im going to use 1 blue spec light with is equal to 225w and  3-4 standard cfl's with are 40w each

so in total I would have 385w would this be ok for one plant

generally for CFL's equivalent is just actual watts times about 4

so a 100W eq bulb uses around 23 actual watts

ow ok thanks for clearing that up im using
blue 65w bulb 4300 lumens
2 x 2700k warm lights (red)with are 14 watts each 769 lumens per lamp
in total i have 5838 lumens in a 1ft*1ft*5ft part of my room at this point can any one advise me on what diffrent plants are the least smellier and a relativly easy first time grow

Go by the actual watts, anything else and you'll be seriously dissapointed with your grow.

you put 2 45 watters on top(or you have a 65 now). then put 2 of those smaller watters ya got there on the sides. and it will be fine, just spin every couple days or day. keep top lights horizontal, as this will put of the most light towards your plant.  keep lights as close as possible to plant. dont wast money ordering you can get cfls at wally world.

hey thanks every one for getting back to me

at the moment i have 4 light fitting in a cross shape like eg

    (2)
      ¦
      ¦
(2)--(1)--(2)
      ¦
      |
    (2)
            (1) = 65w Blue Spectrum 6400k CFL
            (2) = 14w 2700k warm light CFL

Im open for suggestions im thinking about changing 1 of the "(2)" for a
65w red spectrum Cfl what do you think
and the tmp of my grow area at night is ruthly 15c is this ok i havent got the lights in there yet though so that might boost the temprature a bit when thay are in and also where do i take the temrature from near the top of the plant when its in there or just the surounding area i dont know if saw in the pic's but im growing in my shed with has heating,electric,pc etc its like my little get away area this would have no adverse effects on my grow would it
thanks again
Rob
could u sergest any easy beginer seed with as little smell as possible

and any idear's on weather or not a homemade carbon filter would work
what's the average distance the smell would travel eg just the entrance to shed or next door's garden or down the road


i talk .. well type to mutch lol im sorry just trying to gather as mutch information as possible b4 i start my First grow !! :smile:

What horrible advice, don't listen to this. 

You measure light output in lumens, and you want atleast 2,000-3,000 lumens per square foot for good growth.  The more lumens you can put out per watt of power used; the better.  Thats why HID lighting is so efficient.

plants don't photosynthesize lumens, those are a unit for measuring light visible to human eyes. numerous other factors contribute to the photosynthetic potential for a light source than simply lumens

I said lumens were a measurement of light output.  I guess I should have said that a high lumen to watt ratio is one of the reasons HID lights are a good choice.  I was referring to efficiency more on a power usage scale to light produced.
