Sanity Check: White Stuff on Fabric Pot

[Olderfart]

found some real good threads on utilizing them with coco and even auto pots. Looks like my great white has most of the same stuff as recharge, so I’m letting the pots drink what’s in the trays now — in anticipation of dosing them with a great white charge. Once I run out of this I’m gonna check out recharge. Have seen many people mention it. Thanks!

I had the same, and was concerned about it during my grow last winter. Whatever it is, it did no harm that I could detect, so my advice is to ignore it. After the grow, I removed the fabric pots and checked roots, and they were perfectly happy throughout, including next to the pot sides. I was mostly worried that the stuff could be mold just lurking to start bud rot, but I had no hint of it when I harvested, and I know bud rot when I see it. Guess why.

Good luck with it.
