I can agree with that, if using the pellets that are wrapped with a netting. It acts like a filter. I have heard there are some pellets that are not net wrapped, but never seen one other than root starter type of plugs and cheap jiffy starter kits that use those small pellets. Those would make a mess of things if using small spray/drip emitters. When I pull out the plant base after harvest, I would say 99% of the peat is still intact in the netting even with the root mass growing through. Again, I do ebb & flow.
I could not agree more!!
I run dwc buckets with hydrofarm drip kit
