Well, I'm now convinced that all three of the plants remaining from my experiment are, in fact, males.
However, I have learned A LOT from this experiment and intend on getting some good feminized seeds and having a real go at it.
Lessons learned:
1) CFLs are very effective, but I will have to LST next time
2) These plants grow IN SPITE OF my noobishness
3) The area I have set aside for this is MORE than big enough
4) You needn't invest thousands for a personal grow
5) DON'T use Miracle Grow soil!
6) DON'T be intimidated by the seeming complexity of growing these beautiful plants
7) This is fun as hell!
