... back to the whole grow cheap get cheap thing... i dont think this is 100% true... I bought 2 double flouro's (4 tubes in all) as a sort of experiment i have 8 flowering females under them that have about 3 weeks until harvest and im looking at a decent amount of bud all for under $20... im sure i could get alot more with a 400 watter.. but still im not doing badly at all ..
