what are your avg temps and size of grow space?? - thx
avg temp im not sure but the space is maybe about 3 feet wide, by about 4-5 feet deep and i can walk in it. the lights are relatively close to the tops and sides, and they have reflectors
Great looking ladies.I'm planning to set up my own using cfl's and I could use your help.What kind of cfl's are you using? I was thinking about buying cfl's that are labled "day light ",does any one know if these will work.
im using warm ones, wich in my area i only found one store that has them, there like 2 bucks each
Daylight are the best ones to use, because they have the broadest usable spectrum.Quote:

All other factors being equal, more lux on the plant will give you better growth than more red spectrum from less lumens. Understand?
If you have two 25 watt bulbs, one warm and one daylight, the daylight bulb will give more light from the part of the spectrum the plant can use for growth, even though it would prefer more red in the spectrum.
A 600w HPS = 95,000 Lumens
A 400w Metal Halide = 40,000 Lumens
great thread
i am trying a grow with 2-200 watt compact fluro's 36000 total lumens for 4 sq. ft. will post pics soon. i saw a website from uk that has hoods for sale that take 4 and 6 large cfls 125-300 watt ones, the 6 bulb one is approx a sq meter. they have 150 watt bulbs rated at 18,000 lumens also(mine 18000 l for 200 watts). so that 6 bulb hood would be 900 watts and produce 108,000 lumens(approx 12000 lumens per sq here), heat would no longer be an issue in this grow. what you guys think?
Sounds good! I would reccomend leaving room for an extra bulb or two come flower.Quote:

help!!
2700K = warm white, (more red) use in flower cycle.Quote:

You should be good to go.
Don't expect huge yield, but you should be able to grow something worth smoking with that.:thumbsup:
great thankx man, loving this forum very very good info, currently got one in rollitup.org oh yea one more ? should i move the lights that are postion at the bottom to the top??
If your plants are taller than 16 inches, leave a couple of them low. If they are under 16 inches (and they should be if you're using all CFL's), all light from above should get light to all parts of the plant..
Of course, if you plan to scrog (recommended), then all lights should be above the screen.
Hey Steve, (or anyone who knows), How much cooler do the 'cool white' bulbs actually burn, as opposed to, say a daylight bulb? Is there a significant temp decrease?
There's a definite difference. A lot depends on if it's a closet grow or a grow cab. A couple of years ago I had a small grow cab (12" x 24" x 42") and I did all CFL--I had 4 x 26w on the canopy, and 2 x 26w hanging down a little lower. I remember the temp difference was about 3 or 4 degrees during flowering, even with the fan on. So if you're average is in the low 80s during veg, you might be getting into a bad area during flowering unless you increase your ventilation.
Closet are so great because you've got added area for heat dissipation. If you're in a closet, having the door open for a while each day will make up most if not all the temp difference.
its an old post, but a good point.Quote:

hey bobbong if you are still around can you please tell me the exact lights you bought from canadian tire and the exact soil you used because my plant at 1.5 months looks like yours did at 17 days and mine is under 150 watt hps so you are a huge inspiration to me and i want to do everything exactly as you do
Not much difference at all.Quote:

Hey im currently using 3 32w cfl spiral bulbs that say they preform like 150w do you think that they will be enough for four plants?? should i just get more of the same or add a HPS or HID to the mix?????
#1- 64 watts of cfl will cover an area less than 1 foot by 1 foot.Quote:

You really need to read the stickies in the basic growing forums.

Just stopping by to reminisce in my first grow log.
I miss these days.. but i've learned so much from it too.
This thread and all these pictures are simply proof that anyone can do it... and that it's really not that hard.
Put your mind to it, become one with the plant.. and learn as you go.
Cheers,
Bob.:rastasmoke:
And i still can't believe how many views this thread has.. all be it, it's like 2 or 3 threads merged together so the views are also combined but still... 81,000 + views ... damn! :rasta:
Good Luck Keep it up
Lol I haven't been on this site for years. Can't believe this thread lived that long. GJ Bob! :)
Fucking brilliant thread, thanks Bob for giving me a ton of bright ideas for my upcoming grow. :thumbsup::jointsmile:
hahah i got the first post in '09 lol i thikn this tread will go on
hi bobbang did u say that the cfls u use are about 40w but give out about 150w or r u useing 150w bulbs cuz if so they look small and i need to try finding smaller bulbs cuz im useing a large 200w cfl and mine looks about 100 times bigger then urs thanks drater
I got a 68watt soft white for flowering plus 2 40watt bright white. Total luments ~8,000, 105watt 6500k~ 5000lumens plus 4 tubed cool white 1,000lums each. This is in a 1.8x1.8x4 foot box. Right now im just using the higher k bulbs for veg, when i start to flower im going to be using the 68w (soft) + 2 40w (bright) + the 4 tubed cool white. i should have about 12,000lums for flowering. I may scratch that and buy a homebox small and run my 400watt hps, instead of buying a lot of smaller cfls i buy big ones:thumbsup: Homedepot sell's the 68watt soft white ~2700k for 14 bucks, it should be next to the halide bulbs took me a while to find it.
My watts are the actual watts of the cfls.
obviously your using cfls. Just wondering how u stop your plants from reaching for the light like mine do.
Keep the good growing up
Charbud :rasta:
Get the lights real close! u can get them like 4 inches from the tops.
You can actually get them 2" so long as you watch them often :thumbsup:Quote:

I have a 400 watts hps horticlux bulb barely used, that I was thinking of useing for the flower chamber. I have to get a new ballast for my light which is around $130 to $150.
My main concern is that my 400 watt hps horticlux might be too warm for the flower side of the side by side. Also I would hate to spend $130 on a ballast, and it ends up being too warm or hot for my flower chamber.
Would the 400 watt hps horticlux bulb be too hot for my flower chamber?
I was going to leave the fridge on, and turn the freezer part off for the clones. The fridge part gets really chilly.
If 400 is too much would 250 be more ideal or go with compact fluros?
I have to say this thread alone is what made me sign up hehe great info.
Thanks for the input. :thumbsup:
started to read thru and noticed most ppl using 125 watt bulb that only put out 6000 lum here a link to a site that sells 200watt that put out 12,500 lum for around 80 bucks
Discount Hydroponics - MaxLume Compact Fluorescent
not bad if space is tight and heat is a problem
just my 2 cents
