Might be able to use the Sierra Natural Science stuff for mosquitoes. Algae needs light so, as long as it’s dark you should be good there.Question on storing plant water:
I am keeping excess rainwater for my grow in a large rubber barrel in my garage. Probably 50 gallon or more capacity.
Is there anything I can put in the stored water that won't harm my plants, to prevent algae forming, or mosquito larvae away when it starts getting hot here?
They make algicide but I don’t know if I’d risk it on something I was going to consume.
