update:

The last plant finally showed her pistils. 5 out of 7 plants I had in veg have turned female. Pretty good ratio I'd say.

They seem to be loving the hps light. I think I'm going to hold back on cutting the intake hole. They seem to be enjoying life at 82 degrees with only the circulation fan and exhaust.

I'm pretty excited to have had so many turn female.I may go ahead and transfer them into their final pots today now that I know they're all female.
