hahaha. Just so you know. every question on this board is ultimately for Stinky. haha.

she already said it all. My temps go from 72-85 and i've never had a hermie. Though i suppose it's possible, I've never heard of plants hermieing (?) from heat stress, especially from a 75-90 range. Although 90 isn't optimal, it isn't outlandish. Talk to some of the people hittin' 110 degrees!!! Like she said, it's all about stable genetics and good (fresh) airflow.

good luck
