first grow (updated growbox) with pics

as much light as you can cram in there. more light will only ease the situation.

your plant looks like its at a party, nice wall covering

Think of it in terms of lumens rather than watts. The sun provides about 10,000/sq.ft. For indoor growing, you want to shoot for between 2000-3000/sq.ft. So, figure out the area of your growbox and do the math to figure out how many lights it will take to produce between 2000-3000 lumens per square foot.

I believe I read that the ideal amount of light for flowering is 5000-6000 lumens per sq.foot.

Also, I would get some kind of light reflector around your bulb. You lose lumens when the light can get out in 360 degrees.

P.S. I like how the festive reflector turned out haha

You shouldnt have to worry about the CFL. they stay pretty cool. Just remember that weed virtually stops growing over 85 degrees F. so try to gage what temperature it is at the closest point to the light and dont forget to account for the growth that occurs when you aren't looking. CFLs can still burn plants if they touch them.

Take a look at what I did just today with my CFL's. I made a reflector with sheet metal and put 5 bulbs under it. Link to the thread is in my sig

Yes, 5000-6000 lumens/sq.ft. would be ideal, but 2000-3000 lumens/sq.ft. will suitably do the job and it's a more realistic number to shoot for since he is working with such limited space.

glad you notice, my limited space rolla

front to back = 12 inches
side to side = 8 inches
soil to lights = 8 1/2 inches

EDIT
measurements are the space, that my plant occupies
not the whole box, if some of you didn't know... lol

not much space at all
so, i figure, i wouldn't need much lights? for flowering?
just a guess... with a lot of hope... lol

My growspace is 1.8 feet by 1.5 feet - so pretty small. I just calculated the lumens on my bulbs for the first time and its 4x630=2520 + a 1600 lumen bulb = 4120 lumens! That is for the veg. When its time to flower i switch out my 6500k bulbs with 2700k into the same fixture. For some reason the boxes of these have higher lumens. 4x900 = 3600 is the lumens of the 4 small bulbs ( 23watt i think, they are equal to 60w normal lights). Then to give it the extra boost i bought a 300 equivelant bulb. This thing says it puts out 4200 lumens. Niice. That means for flowering It should put out 7800 lumens. More than i thought i was getting. Plus that big bulb only cost me 15.

Pics on the link in my sig with the set up.
