I had one plant give my whole system root rot. I threw it in a stand alone bucket and instead of using voodoo i used hydrogaurd. Also used pirana tarantula sensizym and bases. The root rot came back for the plants in the system which had a cooler hooked up, the bucket didn't. All buckets in system and the standalone were cleaned the same way. The bucket in fact didn't even have duct tape around it for light proofing, just a plain lowes bucket. The standalone did get less direct sunlight tho being left outside the grow room. The standalone also had old airstones in it from when the root rot was around. The case on the standalone was also ALOT worse and I thought it was going to die, but I had my dirt ready to move it over, expecting nasty roots I pulled it out and clean white roots. I think I will keep this oneinhydro and not give up on it. So bassically what I'm saying is I provided this one with conditions that I would really expect to make root rot worse and gave it hydrogaurd instead of voodoo. Treated the other ones great with a cooler, fresh airstones, fresh tubing and I gave them voodoo juice instead. The skywalker was in a standalone because I was scared it would make the others worse. The reason I mention this is because hydrogaurd is a lot cheaper and I saw better results with it. Anyone else have input on this?
