well im going to start growing as soon as i get some lighting. i was going to go with a HID light but since i just don't care about yield i'm going with cfls.
anyway back on topic, two questions

How many 42 watt CFLs would be good enough for one plant?

What should i get, Full Spectrum, Warm White, Cool White? Or a combo of the three?

I am planning a similiar grow, just one plant for personal usage and I am going to use (4) 42watt cfl for my one plant. I am planning on using the full spectrum, depending how much attention to detail you want, the warm white and the cool white are both good to use however one is for the vegetative cycle and one is better for the flowering cycle I am not sure which is which though, look around some of the faq's and i'm sure it will answer that question for you... good luck with the grow, are you planning on making a journal?

yeah i might start a journal, still deciding. good luck with yours as well

are you growing from seed? what if that one plant is a male? or becomes a hermie? or you fuck up and it dies? try 5 plants and finish the best girl.

for one plant i'd get a 3 socket bathroom vanity style fixture, 3 two output socket adapters, 6 35watt or 42watt cfls. that'd give you about 15,000 lumens. good for a square foot. half your bulbs should be a warm white(2800k), half cool white(6500k). scrog it for max yield. maybe 4 ounces tops.

cost you 50 dollars to put that together.

Hey guys i got 8 42 cfls 2700 each + 2 23watt cfls 900 lumens each is that enough lumesn to flower 3-4 plants?? around 21 thousand lumens

I have 4 42W CFL's and 3 32 W CFLS almost all soft white... for 1 small plant... I'm not really impressed by the growth... So I'm just going to buy a cheep HPS.

you should be able to do 3-4 plants under 21,000 lumens nicely. Heat will be an Small issue because of how close you need to keep the lights to the plants (under 6"). The 42W'ers get a bit warm. As far as what color bulbs for what stage. Use a mixture for both stages but lean towards cool white(blue spectrum) for vegging and warm white(red spectrum) for flowering. The blue light keeps the plants short and grows big roots. Big roots=big buds. The red spectrum makes the plant stretch and grow buds. Hope this helps

also try keeping your grow area to around 1sq/ft per plant.
