You'll soon see I do everything in a roundabout manner fIll that tank as a reservoir, then run hose lines downgrade to the other containers where I do my mixing and that’s where I draw from .. now today it became obvious with the pressure wand I can save a lot of work pre-watering directly with the freaking wand..that’s what it’s designed for I’m so dense of brain…(rather than hauling everything around in 2.5 gallon Watering jugs) and then going back again with feed..
