Hi all
I'm running RDWC, second res is outside of the grow tent. This is where I keep the air pump and where I put frozen bottles to cool off the water. The roots of my plants have reached res bottom quite a while ago. In my previous grow, I've disconnected the pumps after three weeks. But then, I had only one res and top feed wasn't necessary after the roots reached the water.
Now, in this configuration, the pump is essential for cooling off the res and I need it to run 24/7.
My question is: Should I remove the feed tubes from the rockwool and let them simply sink down into the res (they would still be pumping and exchanging water), or should I leave them pumping cool water over the base of the roots, just the way they are now, for the entire duration of the grow?
Would this continuous water flow somehow be, if not damaging, then less beneficial to the roots? I don't think so but would like to hear what the more experienced of you have to say. This is only my second hydro grow.
Thanks for your time.
