Hermies on one tent

Thank you for your tips. However I still have one question. If I start the second tent with some seeds in a week, by the time I'll turn them to flowering the hermies will be finished. So will there still be pollen flying around?

Though pollen doesnt stay viable for very long it is known to travel for miles if it has a decent breeze, i would either watch the hermied plants extremely closely or just get rid of them. If you dont mind checking them pretty thoroughly just about every day you could chance it and just pinch pollen sacks as they appear to minimize and chance of pollination, also if you add exhaust so there is negative pressure inside the tent (always sucking air) that should decrease the chances of polle. Escaping as well, but youll need to change clothes before checking your other plants.
