Right now I'm running 400w powerplant hps, with light bio grow (will start to up it soon) in PM+ soil.
things are looking swell (ladies are quite short and bushy, but they might shoot up because i moved my light up 6" yesterday)
I'll be adding bizz bloom to the mix, alongside some mollasses in the last few weeks.
I'm also considering running a blue cfl in there as a close sidelight to encourage the branching, which means i can put my hps a little higher without worrying about stretching, and they'll get the benefit of a dual spectrum
I'm hoping that with the cfl, i can run my fans at intervals rather than on 24/7, which they are on now due to the heat from keeping the hps close **costing me a fortune in electric**
