Is anyone used these for growing? Are they OK for LST training or do they need to be mixed in with something else? Are they safe to use in the first place in Hydro? ( I know it's a bit redundant, but that's actually the point, I'm looking for something that I could put the early routes into both for the ceiling phase but also just in case of a brownout/blackout in my area as we are headed into the summer months.
