Hey, Iv just started a new grow in a 12 pot IWS flood and drain. The plants are only in the system 3 days (2weeks old) I took some of the pots out of the buckets today and noticed some light white mold growing out through the holes. Iv never seen this before. What can I do? I’ve tried to remove as much as possible. Iv searched online and all the advice says to keep them in a well circulated area with low humidity and direct light. I can’t do that with this system, it’s desgined to keep small amounts of water at the bottom of the bucket to keep the roots moist. How do I prevent mold from growing in this sort of environment ? No lights gets in and no air moving. It’s the perfect place for mold. Help!!
