Short answer: will be harvesting 2 plants within 5 days.
If you think what I have posted is too much, I will happily delete, but thought growers might want to know the main cause of Root Rot. Several advanced growers here and elsewhere offered their knowledge, but none figured it out. The back and forth got heated, and I stopped posting to my thread here and one other popular site
I am happy to say that after 4 straight grows where my plants all died of RR, and in this grow, should have, I finally figured out what the cause was. Over the years my methods included HPA, DWC, F & D, then I got an idea to try LPA (using HPA mist heads and a large GPH pump. When you see the root pics, you'll see it has great promise, as well as see the problem: the spray was hitting the underside of the lid and penetrating deep into the net pots.
I always start seedlings/clones in my DIY bubbler, then transfer to my DIY F & D, very successfully. But I decided to push it by increasing feed cycles to hourly, which should work, BUT, I set the water level too high, which, unknowingly, was soaking the starter cubes 24/7. After 2 failed grows, I decided to try low pressure aero + HPA mist heads. I had great root development, but then the dreaded RR. So, I went back to bubbler, but this time with a twist. I have been on a quest to optimize DO for several years, while eliminating air stones.
This time I developed a super technique using a plastic bottle half filled with platonic solids and marbles with a pump inserted into the mouth. I drilled holes in the bottle, but the pump was too big (or the tote was to shallow). All of these would work great, but all suffered from the same issue: my starter cubes were getting soaked 24/7, thereby creating the environment for the dreaded root rot. Here's pics of each +plus this saved grow (last 2 pics) which is within 5 days of harvest. She's 40" tall, the plant from the ugly pics with RR. Should be smooth sailing from now on
