This is what i am dealing with, broke off most of the root web inside the tray when i pulled this stalk out, got like 50 perc good roots and 50 percent bad roots. However i’ve done a complete clean with bleach solution and soaking of roots. Wish me luck.
YES! I have a supercloset or something and my plants start rising up on the roots because the tube/tray isnt deep enough. Started growing last April 1st and have made several modifications after getting root rot. 1st is pitched tube/trays back to the tank so they fully drain in-between cycles. 2nd- lay a piece of .5" or bigger tubing in the tube because the roots will totally block off any nutrients from flowing to the end of the tube. 3- Add more air stones! I have 12"×1" stones in the tubes. It really helps. Fresh air inbetween feedings with them too.
Going to switch eventually to aeroponic.
It’s a trough type system with 5 4" baskets in each. I just lay a piece of tubing in the bottom to give the solution a way past the root system of the first plants because the drain and fill are next to each other on one end. They act like a mini Hoover dam.
