Auto-Flowering Lighting

I am planning to grow 2 maybe 3 small auto-flowering plants in about small 3x4 enclosure with some ventilation, and was thinking about using CFLs. also i am planning on using mylar diamond reflective sheeting- is this good? and What would be the recommended watt output for optimal growth?

not sure, but interested too, ive read in other places from 2 to 5 thousand lumens per sq. foot of floor space (minimum).

Also should i use red or blue spectrum lights?

You can get alot more in that area.But 2-3, 150 watts.They grow about 18" tall.

not tru, i have a blowfish it would be like 7ft including the pot if i were to not bend it. im using 2 150 cfls on a bright wing 1 red 1 blue and using red side lighting, i beleive that you want like 1/3 in the blue spectrum and 2/3 in the red. blowfish is a bigass plant tho and grows very fast. (G13, blue dot, oregon funk) i will never grow this one indoor again.

I heard for auto-flowering it really dosnt matter which spectrum you use,or if you mix them, but i want to get the most out of my plants so What are the advatages of mixing up the light spectrum with 1/3 blue, 2/3 red?? or is there any at all?
