I observed early pistils too. The great thing about my keeper is that it doesn't even need odour control as yet unless I do some husbandry like last night's backbuilding.
The thing I will say though is that I did find one male flower in the understorey (probably caused by stress in the rootzone, like EC above 5.0 and pH11 in runoff before I stopped being lazy, flushed then started using RO and calmag!). Luckily I got to it before it opened and has since been vaped

I had to cull my third while still young as it immediately showed a ball. To be expected from the hermie ancestry, I guess.
My second one is a different story entirely and is quite loud - it lives outside to slow the growth (nights still dipping into freezing) until I, or nature, flower her.
I have some GG1 beans on the way to hopefully do some tinkering in the future.
