@bounzingball, I'm definitely looking into more this week as I'm using 14l fabrics and there smashing it for me. My last two lots did me well.
I want to see how these would do so I'll run them next so in 4 weeks.
Also with lighting, if cfl or lef I'd go 30-40 cm to start. As you get to week 2 veg I'd look for a 250/400w hps to finish veg into flower. Then finish off with a nice 600w hps for flower. I'm not using these leds as alot of final product is alot less in exp from friends so I'm sticking with my hps till I'm shown different.
