Biobizz is a hard grow but great results when you know how, any ferts will do imo.
For the discussion over lights -
I would not like to try LeD's simply for the price and a HpS gives lots better penetration. From my own experience with CFL's (i flower with 2x250watter) i would say that my 500watts of cfls is probably equivelant to a 250watt HpS judging from yeilds and plant growth.
The future is certainly HpS in an aircooled reflector until Plasma lights manage to get more of the red spectrum in there. The problem i have with LeDs is that i know i can grow faster and heavier yeilds under HpS and have never seen a side by side comparison where the same watts LeD out grew an HpS.
You LeD growers have to realise that when Plasma gets just a little better it will not only out grow LeDs many times over but cost less. Personally i would have a 300watt plasma light right now and pay the price, they look really really awsome and those square reflectors they got mean perfect for a square grow. Thses lights have been lighting the important sport venues and certain other places over any light for years. When they get slightly more suited for flowering and not veg no one will grow with LeDs again prefering to spend the same money on pretty much pure sunlight/Plasma instead.
I feel LeD's technology means that when they finally get real good Plasma will be far outclassing it. Led growers can say what they want but any plasma growers will simply wipe the floor with them, against HpS you got a small point, against Plasma and your just that small light in my phone etc etc because you wont get the time of day after they tweak a few things. Sorry to have to let all Led growers down but go on youtube anbd see what 300watts of plasma dose!! LeD what!!!! Peace
