Ah wha that's no good, I sure hope I don't run into root issues. They seem to be a major issue for hydro grows tho, going to definitely tty my best. But I'm sure I'll have my share of scares, as for a shop vac no I don't have one at the moment I think I knownwhrre your going with it. I definitely need a shop vac lol would make cleaning the buckets out easier
Hydroguard every time you add water. My nute solution in my buckets almost always runs 70-76deg F. Add 2ml to each US gallon. I usually dose on the heavy side.
