Will this work for 1 plant, big yield? or 2 plants?

Im gonna use
3x 30 Watt - CFL -6400K [2000lumens each]
4x 42 Watt - CFL -2700K [2800 lumens each]

Im gonna be using this in a cardbox box stacked in a 3sq. ft. by 1sq. ft. maybe 4-5 ft tall.

tell me what you think! i added it up

2800 x 4 = 11200[2700k] lumens
2000 x 3 = 600[6500k] lumens

input appreciated guys.

well hmmm 2700k is used for Flowering so u can have a couple in there but not that many personally. I would get maybe one more 6400 so u have 4 6400 and then use 2 2700k and then when u switch to flowering use 4 2700k and then 2 6400 k that si what i think. but yea that is enough room, just amke sure u have some vents

Have ya read doc chronic cfl guide? https://www.rollitup.org/cfl-growing/107992-tutorial-growing-cfls.html it will help outline spectrums.

yeah! im gonna mix the spectrums a bit alil of the 2700k on the veg period and alil 6500k on the flowering stage also, i heard somewhere it helps with the plants growth giving it abit of everything. thanks for the response mike!

I would go with one big plant. You can get better coverage that way. I use mix spectrum for veg and then switch to all 2700s for flowering.

I want to make my own fan for my grow op. I only have 6-9volt out phone chargers, may i use that instead of a 12v? + computer fan

It is just going to be weak as hell. I think you would be better off getting one 12V from radio shack and run a couple of those fans and a small desk fan for circulation. This should be good for your light setup. You definitely dont need a vortex fan or anything like that.
