Lighting

What would a 400w CFL lightbulb do for a micro grow? Would you need to keep the bulb close to the plants in the same way as the other ones

2 x 200w cfls is better

one at warm white ...2700 kelvin

the other

cool white at 6500 k

will grow a better shape plant

see it as red warm white for vertical growth

and the blue ..cool white for the horizontal growth

good luck

I've got four 2700s and four 6500s how will that work do you think? And thanks for the response!!!
