I have been using EnF since day 1 and after seeds germ I put them in 1 inch RW cubes until roots show out bottom. Then they get placed into a 4x4x4 RW cube. When roots start showing from this they get placed into there grow tray which is about half full of Hydrotron and they start the flood and drain sequence. Now I have read that some peeps "bury" the RW into the Hydrotron but I have had no problems setting the 4in RW on top of the layer of Hydrotron (aprox 1-2 in deep) and the roots just migrate into the hydrotron. Tray floods every 4 hours and pump runs for 15 mins. Flooding only happens when light is on and first flood takes place 1 hour after light turns on. I have no pest, disease or algae probs to speak of. Hope this helps ya.
tinytoon Reviewed by tinytoon on . What should I put my plants in if I use an Ebb & Flow watering system? The grow space I am making uses a ebb & flow hydroponic watering system. I was planning on putting the seeds in rockwool and then putting them in the ebb & flow. Rating: 5
