Mould on fabric pots

lochem said:

So I’ve got what looks like a bit of mould growing on the outside of one of my 3 gallon fabric pots.
I’m in a very small tent (80x80x180cm).
I have plenty of ventilation in, out and around the inside and my temps and RH are good. Under control and monitored.
My question is really: how can I safely treat this before it spreads because we all know it will spread.
The reason it’s started at all is because of my drain-to-waste setup. See pics for a visual explanation.
the plants are sitting on a drain tray inside a catchment tray and I have tried many ways to deal with DTW in my setup and honestly this is the easiest for letting it all drain through the pots when I feed and then I either dump from the side of the catchment tray or it just sits there and evaporates.

Most likely what you are seeing is salt residue from your feedings. As the feed drains through the cloth pots some of the salts in the nutrient feed get stuck in the cloth. As the cloth starts to dry out it leaves behind the white chalky salt residue on the outside of the pots.

I don't see any issues with the setup. A damp cloth should remove it from the outside of the pot. I'm DTW in coco and a sample of my 3 gallon cloth pots by the time they are in mid to late flower.

If you're pots are off the ground your run off is easily emptied with a piece of capillary mating, it just does it without any intervention from me once it's in place.

I would expect salt to show in the drier warmer areas and be less visible when wet?

Very interesting idea. So it just soaks it up and then drips down into a jug or something.... I’ve never seen that kind of thing where would I find it
