The Recharge has arrived. It seems like a pretty good deal, 8 ounces and 1/2 teaspoon per gallon will make a lot of tea. Another thing I like about it, it's completely soluble. It probably uses a filler but whatever it is it's not clay or other material that will create an instant residue.
I've cleaned the grow station as well as I can. I suspect there are spores that survived. As an additional measure I've brewed some tea and added it to the rez. I'll be adding more tea every couple days until the clones are ready at which point I'll sanitize the system again and start a new cycle.
Nothing new to report with the clones. Day 7, no sign of roots.
As mentioned, water pumps don't survive being simmered. Also, the suction cups and o rings don't do well in 30,000 ppm sodium hypochlorite. Cups and o-rings can be removed, so it's still possible to soak them in heavy bleach. Whether there are internal parts that will dissolve after repeated applications I'm not sure. I plan on treating the pump with the same solution between grows so if it fails in the future I'll report it.
