Light spectrum is everything. 6500k for veg and 2700k for flower. Some variance is ok, but 16000k is no good. They will take it back at walmart. Find a light in the right spectrum for the cycle you are on.Its just a regular cfl light from walmarts, regular screw bulb and everything , they had 40 60 100watts.
Is not a cfl light a cfl light?
lol ok that is better, what color temp though.Sorry, I made a Mistake, Its 16000 Lumens, what you u think of that?
And thanks for helping
I bet you are right about the actual wattage.Daylight is generally 6500k which is good for vegging. Soft white is generally 2700k which is good for 12/12 or flower. The 100w is most likely a watt equivallent and only 23-26 true watts. You probably need at least 3 of those per plant and keep them about 2 in off the top while maitaining temps. The more the merrier as long as you can keep temps about 85 or less
Good...cant do too much with cfl.If you plan on using cfl's do a mix.
say 6 of the 6500k and 3 of the 2700k. use this combo for veg.
and reverse it for flower.
I wouldnt say there is a proper lumen range. well there is, but think of it this way, the more lumens the better the lighting. The better the lighting, the better the plants.
