I have been a lazy dirt head for some time now.. almost finishing up with my current grow that consists of 4 4x8 flood table with 3 gallon dirt pots on them.. my question is what is the best way to switch out of dirt while using my tables that I paid for? I was thinking of rockwool cubes on the tables but have no experience with it and what method to use? I am trying to stay away from the flood and drain if possible.. any input or ideas?
