really? I get my 18 done with about 4-5 gallons. I use a 2 gallon round up sprayer with the misting wand from a 1 gallon round up sprayer (or flo-master as they are the same thing. Every time I go to walmart or home depot, I cannibalize and five-finger the blue internal atomizer tip from another sprayer so that when I am spraying and the little blue tip gets clogged, i just swap it out and move on. I make sure the box is left wide open so no unsuspecting fool buys an incomplete sprayer.
The bigger sprayer comes with a heavy duty wand, but the flow is too heavy. I find it wasteful. I feel like the combo I have come up with coats plants with enough without being wasteful. It kinda defeats the purpose of spraying against mold while at the same time getting a bunch of extra moisture on the plants that is going to seep into your buds and cause botrytis... which you will then have to combat with an overly heavy application of the potassium bicarbonate.... which gets more moisture in your buds... i try to avoid feedback loops whenever possible.
