I made these corrugated pvc covers to keep the roots covered as they root into the Grodan blocks. I see a lot of space around the "Rootit" starter when it sits in the Grodan block, and didn't want to expose the roots. Now I am noticing roots growing out near the top top of the rockwool from the starter sponge. If this doesn't make sense, please look at the pics. My question is, are the covers doing more harm than good?
