Terrible, I'll have to throw 100 lbs of it away
Bought for hydroponic use. I tried dissolving this stuff in water for a 10:1 concentrate as I do all the time. At first I noticed a lot of floating precipitate and figured there was some poor purity as its a cheaper product, not a big deal I could take the extra step of prefiltering as I dissolved it. Then I noticed everything the mixture touched had a viscous layer like emulsified fat. It's clogging filters and I'm expecting clogged emitters any time now. I have 2 bags of this stuff I'll have to dispose of as I just dont think I can make use of it.
