I’ve grown a few SSDD’s. I have a pm issue, so I sweep them every day with a clearlight uv-c thing, and the SSDD’s haven’t had pm, or botrytris while other strains have… knock on wood! I do try to keep the RH in the grow space below 60%. In the summer I have a dehuey running 24/7. 70% could be a problem.
SSDD is my desert island weed. I try to always have at least one going.
This one is going now, 49 days.
Yours look great!
