I just grew a NL x BB plant to harvest and was very pleased with the finished product. It is a tall plant
and I had to prop up the main cola after 3-4 weeks flowering to keep it from falling over.
So switch to 12/12 and be prepared to jump in with pipecleaners or whatever you use for braces. I found
the NL x BB to be quick-flowering and harvested her after 5 1/2 weeks flowering. Dried 36 grams from a 2 1/2 gallon pot.
Good luck, BigSteve.
