Papa_Tanswered grow question 5 months ago I’m suspecting that they lay flat on their belly in a tray all day in their puddle of pee. I’d suggest getting pot risers for your tray so that the pot can breathe underneath.
You need that moisture to wick away underneath. No airflow causes issues.
Check out the Gro Pro NX pot risers. They got different sizes and 5 bucks a piece. If you find them for any more than that they’re trying to fleece you.
