yes, but it does not fit with my grow room setup.
use above 200 watt bulbs will create problems.

If you have a winged reflector a great way to keep them cool is get yourself a small pc fan like grow demon suggested but what I did was mount it at the end of the fixture with paper clips blowing directly back at the bulb, direct your oscilating fan on the ground blowing the same direction and up, it makes a little vortex of air movement going up and away an helps greatly. I ran a 600 watt in a 30x30 closet with a winged reflector this way with a passive intake and a 6" inline fan for exhaust. Get your airflow corrected and you will be fine

alright mr. Jbone77, let's turn it slow down.

I mean if you look at your plants. they look just fine under the 4 cfl's you had.. they are just a little nute burned on the tips.
they sure got pretty big for just 4 bulbs. let that speak for its self

oh my god, you know i'm using cardboard box? LOL
it's awesome, you can using unused goods for a growing.
ya, I think this is quite using CFLs. maybe I'll add some more lights.

did you know about sativa strain?
i mean, 100% pure sativa.
i've got much seeds pure sativa. do you want it?

this a cardboard box growroom. :D

yea as I suspected!! very nice, prob the best paper box setup ive ever seen.

ok if this is the case here is what I would do. your using almost the same amount of space I am.

the trick to cfl growing is getting a nice good even spread of a light array over your plants.

so to remedy this, I did about 8 months of research before I dove into a cfl setup. and what I came up with has worked.
1. cfl lights emit more light on the sides
2. the more lights the better
3. a couple fans in various spots to create a wind tunnel of air flow ( as jbone77 mentioned )
4. I find that 24w bulbs work fine (and keep the heat very low) 1600-1750 lumen each
5. for flowering I use 8-14bulbs depending on how many plants (which the results are in my user profile photo album you can look)
6. total watts for my 8 bulbs is 192w which is around 15,000 lumen
7. with 14 bulbs its around 25,000 lumen

now you could use stronger bulbs & fewer of them, but they will get hotter much much hotter, 2 125-150w cfl grow bulbs puts out as much heat as 20 24w bulbs. now the 24w bulbs are spaced out far enuph apart so it allows the air flow tunnel to dissipate the heat much faster.

here is what you should look into getting for a decent cfl setup with a proper light spread
goto your local hardware store, get
1. 4-8 socket vanity mirror fixture $9-15.00 (im using- Hampton Bay Brushed Nickel 4-Light Bath Bar from home depot)
2. power cable to wire it $5.00
3. four Y bulb splitters ( the splitter are very important because it will angle the cfl bulb so more usable light is seen and consumed by the plant)
4. 4-8 bulbs you can expand as your plants grow
5. 1 fan blowing on the bulbs or near them to dissipate the little heat they do emit
5b. 1 fan to blow slow wind on your plants to strengthen the stalk so it can hold BIG BUDS!
6. roll of thin metal to make a reflector if you need
7. chain to hoist it
8. something to hold everything, Im using a pvc pipe hanging rig that I made

also if you want taller plants you need to move your lights farther away from the plant, I just harvest three 4.5 ft plants grown under cfl's. So tall plants can be done its just the lower portions don't get enuph light. so what. I added more light on the lower sides, and anything that grows scraggly I use them as a seed farm to create my own seeds/strain, works like a charm.

here some pics of the various stages of my light setup

:thumbsup:

so better use cfl's 24 watt?
I just planted 2 pieces only, how much should I add?

well its not necessarily better. but for your conditions/ YES its better.

your originally had, 4 20w. not sure the output on those, I have never seen a 20w bulb. it prob is a 23/24w

a 24w bulb is 1750 lumen
a 23w is 1600 lumen

4x1750 = 7,000 lumen. plenty to grow green.

when you flower, add 4 more, and spread them out, in a row on top pointing Sideways

start by:
add 2 more. and see how the heat is. if its good.
then add 2 more,.. get it!>?

8 bulbs should be perfect for that space, get some Fans too!

here try this
Example of Estimating Number of CFLs Needed For Your Grow Space:
1.
Multiple width x length of your grow space to determine the sq feet.
Let’s say your grow space is 2’ x 2’ = 4 sq feet

2.
Multiple the sq feet of your space by 4,000 lumens to determine the total lumens needed for this space.
So 4 sq feet x 4,000 lumens/sq feet = 16,000 total lumens for that space

3.
Divide this number by the lumens produced by each bulb
If you’re getting 42W CFLs which are rated at 2,650 lumens apiece, that would be 16,000/2,650 = ~6

4.
This number is the minimum number of CFLs needed for your space
That means in this case you’d start with 6 (or more) 42W CFLs

hey growdemon 4x1750 = 1750 4 difrent places on the cannabis you will never get 7.000 lumen on 1 place with what you are talking about im sorry to say but you wont if you place 4 lights you will just get 1750 4 difrent places on the top of the cannabis

OK, sorry I did not tell the specs before.
it is:
1.5M high
1/2m X 1M wide
total plant 2pcs
strain : pineapple chunk and royal dwarf
light : 4pcs 20 watt's 2700K + 1pcs 22 watt 6500K
related temp : 29C degree ~ 32C degree
related humidity : 50% ~ 70%
air intek : 2pcs 12cm fan
air exhaust : 2pcs 12cm fan
additional fan : 1pcs 30cm
co2 maker

grow tent made from mulse plastic with pvc pipe, and a cardbox for hiding light out. 10M white vinyl sticker for refletive wall.

soil mix with perlite, goat manure, husk fuel.

fertilizer :
Npk 29+10+10+3 (veg stage)
nPk 15+30+15 (flowering stage)


and i think, i need 32000 lumen

I am in 9 square feet, same as you.

ive been doing tests,
1st grow 8,000 lumen 1 plant 4 bulbs 150w/75w/24w
2nd grow 15,000 lumen 6 plants 8 bulbs all 24w
3rd grow 25,000 lumen 15 plants 14 bulbs all 24w


satisfied each time! that's a fact

thanks dude, you have guided me for this.
Today I have bought 3pcs 35 watt 6500K CFL's. but I have not tried it, because I'm working.

anyone of you want to plan a vacation to asia?
contact me if you want.
