3. CFLs are not cheaper per lumen as HIDs, but for a small grow can still be very economical.

4. Look at lumens, its suggested to have a minimum of 3,000 lumens per square foot of grow space. with a standard 100watt equivalent cfl bulb making 1,700 lumens, 2 per square foot is about right.
Well i thought it would make a great sticky, but thought id wait to see what kind of info we get. If we continue to get the stuff like you just providid, its gotta be a sticky.

Its interesting because my 26wer's say that they are 1,750? Plus the 30w i just got said 2,100 lumen's. Also, many are not marked as cool, or warm. Not a one of mine were.

Well lets hope this thread takes off:rasta:
