something not intended to keep joe biden happy when he's reading up on the implementation of socialism.
A real light, is one specifically designed to do what it is that we are asking it to do. A cfl is an eco-nut oxymoron that has no real value in growing cannibus.
You want good weed, you need good light. There is no way around that fact. Even if you do get 600 watts worth of cfl, you not only have created a heater, and a fire hazard, you still aren't going to get but 1/3 of the lumens that you would get from a real light.
The only advice i will ever give a grower who is using a cfl, is to get rid of the cfl. Once they decide to take their garden seriously, then i'll take them seriously enough to help them out.
