I'm in the final 2 weeks before harvesting... I'm growing in a dwc/aeropnic 40 gallon tote, Plants Look Great, white roots, Everything seeems good, but i was messing around in the rez today and my had bumped the roots, They were solid and wouldnt bend for like the first 6 inches under the net pot.. They never were before, is this Normal? should i be concerned, i haven't read anything about this anywhere.... Hmmm anyone familiar with this?
