Re: Misters
Craig,
I have never used these in a green house. Although in one of Joel Hollands
videos it does demonstrate them being used inside a green house clouche. Yes
they can be used for applying fert. providing you are using a foliar fert.
and in low doses. I believe Jon Hunt' system was set up this way where by it
regularly fed the plants fert. everytime the system came on!
