What about the anti root rot stuff? Is it worth it?
Well for me it's definitely worth it. I run a 20 and 10 gallon reservoir for ebb and flow and my temps run up to the mid to upper 70's at times and I use z7 in both of them. Can't vouch for other products that are similar because I'm really happy with the z7. Also plan on using it in my cloner bucket for the fist time soon.
