I just bought a 3' x 3' ebbflow hydro system and was wanting to see what most people use as their medium in the pots. I am going to put my clones in rapid rooters and have like 20 or 25 pots in the system.
I was wanting to do hydrotron or the coconut. I was not wanting to do the hydrotron in the whole tray though, just in the pots. I have heard that coco stuff works good.
