CFLs for flowering? How Many? What Spectrum?

Its my first time and I want to know if CFLs will work instead of an HID light. My box is a narrow 2 cubic feet with room for 2-4 plants depending how big of pots I go with. Anyway, Im thinking of using 100 watt CFLs so I still get high lumens without heating up my small box to a million degrees. Low cost is also a must for me. I know they work for veg but what about flowering? How many 100 watt lights should I use? Do I use a mix of Colors?

Any Help is much appreciated:bigjoint:

i use cfls all the way,definately use them if you only have a small space n few plants,blue spectrum for veg,red for flower,check out my pics,i do ok n i cram the buggers in lol,i get too greedy,i dont veg them for long so that they dont grow very high because my height space is limited

it'll work, most will say 6500k (daylight) for veg and 2700k (soft white) for flowering. for a small scale grow it's not going to make too much difference especially since vegetative growth isn't important to you in such a small space.

i think you could get away with one 45 watt CFL (the one that is rated at 150w equivalent) or a couple 23 watt (100 watt equivalent) CFL's and still flower, be warned you may get a few grams and that's prolly it.

i had one cfl,5 10" plants and i got nearly 3oz....did pretty well i thought,put them into flower 10days from seed so i had kind of a sog setup goin on except it was more like a puddle than a sea

I think im going to go with 4 100w. You said 23w is equal to 100w but what I have now says 100w on the package so Im not sure whats what 2 of each color. Would this get me through a whole grow with good results?

Also, I want to hame a DIY hood. Anyone have good plans for a super cheap lighting hood?

When you say SOG, sea of green right? Does that just mean lots of little plants with short grow periods? 10 days from seed seems very short from what Ive read.

ye sea of green,its short from what iv read aswel,many people have said that it will cause stress to the plants makin them male or only bud a little bit,but i only had 1 male,whereas the grow before wen i vegged them for a month had 2 males.....most people THINK they know best on here but they dont.i did it cos i dont have much space so with flowering them young they dont grow very tall and they concentrate more on the top colas instead of puttin there energy into the tiny buds around the bottom,my advice to you,is experiment,fuck what everyone else says (within reason) and just go for it,you'l be pleased with whatever you get

and another thing,people wa tellin me that u should only have few plants to one cfl.....my first grow had 6 plants ,
and i dont use a fan
obviously if u hav a stronger bulb the results will be better,thats just common sense,.........but im happy with my setup at the mo

This is my first grow and I've been using CFLs and I love them I got one plant in a 3 cubic foot area (due to the fact my other 2 plants were male). I average about 3 inchs every 24 hours and I'm using them for flower right now and the seem to be doing wonderful, I would Def say go CFL!!!

whoever said they got 3 oz off of one cfl is lying.

unless it was one big ass cfl!

yeah and in addition to above poster miracle gro potting soil is over-nuted and will burn plants, you can grow with it but it is harsh on the plants especially at the seedling stage. miracle gro organic choice potting soil will work however, since it isn't so heavily nuted (it's nuted organically with chicken shit instead of high doses of chemicals).

and 400 watts of CFL doesn't come close to 400 watt hps. i would rate it about as effective as a 150 or MAYBE a 250 watt hps.
