gb, pollen got on all 5. Pisses me off too. My fault, should have only had 3 growing. I tried something new: a very large SIP holding all of them so I could spin it all at once instead of juggling individual pots.
All that soil means much less watering and disturbing them raising the chance of Pollination, well that was the idea.
I should have supplied a/c to the room, especially since it was available.
