After growing ebb and flow in two 4 x 4 tents for the last 10 years, I decided to try Coco core in drain to waste. I built a small 4 plant system and I’m in the second week of veg. All is well.
Question is, what to do with all the run off? Can you use lt again in the early stage of growth? I feel guilty dumping it down the drain.
If you have a yard your landscaping will get good boost from it.
That's what I do - house plants, trees and shrubs around the yard and tossed out on the lawn. Not a lot left in the solution, but may as well take advantage of it instead of sending it for waste water treatment or into a septic tank.
