Are you using HPS or something different for lighting. Everything so far sounds good except the flowering period. Most of what I grow says 8 weeks to flower ,although I usually find that I have to give them an extra week.If the extra two weeks is worth it , I'd be willing to give it a shot.Also , are you growing hydro or soil media?I don't know if you re-veg your plants , but I try to when they co-operate.If you do re-veg , please keep me up to date on how this plant does with that.Any help is much appreciated.
