these pics should better explain things.


I have two trays that are actually designed for Rockwool slabs, but I filled them with Hydroton and Transplanted my Rockwool into the hydroton. I flood the troughs, and it drains back to ther res by gravity. I keep one side higher than the other with books so it drains freely.

I had some overflow issues when I first started and I also ran into some over watering problems, but Throughout the grow ive worked out the kinks and I got everything dialed in before I flowered them.

Very simple setup. Flood the trays and let gravity drain it back. I like simple.:thumbsup::jointsmile:

sorry for the shitty pic.
