Outdoor hydro. The temps were the problem and also I had 2 root die-offs, plus my ph was way too high. It was very strange. The plants didn't burn, they just didn't grow at all. They were miniature plants. Once I got my ph fixed and started leaving them inside, they took off. I am growing another set of seedlings and my soil growth is at least 2x larger than the hydro plants with seeds started the same day. I'm using gh nutes and correct ph, so I'm not really sure what is going on. They are under the same lights. The ones in soil are closer to the light by a couple of inches. I guess that's the difference, cause everything else is the same except the medium I'm growing them in.
Gen Reviewed by Gen on . root rot ok to answer one of my own questions, what causes root rot. It's due to low oxygen levels and temperatures. Low temperatures lower dissolved (DO) oxygen levels and high temperatures will also cause DO to be low. So if you have algae growing that's your problem. This also comes from ic forum. Rating: 5
