Shit is nasty. If you think this stuff can improve your crops, you are growing absolute booboo. This is honesty,not opinion. It doesn't raise Brix. These gimmick products are contaminants.
Most have mag+sulfur. I live in Az and dispos use this crap all day. Its the only smell most the bud has other than hay,and it makes me puke. Organic weed helps my stomach. Artificial Sweetener bud makes me sick. Thats all i need to know. Oh, plus the black crust that builds up on my vape glass, kinda indicates what smoking Epsoms orange peel sugar water does to the lungs.
Use natural products and use them at least 2 weeks before chop. Or nothing at all. Swollen buds full of sugar... Thats your "increased yield" its no different than spraying buds with honey water. Same. Exact. Bullshit.
