What makes Plant Guard 420 different?

  • Most sprays make a choice: kill the pathogen or protect the plant. They can't do both. Sulfur burns. Neem coats. Copper leaves residue. Every one of them has a cost you pay at harvest.

  • Plant Guard 420 is a proprietary potassium-based hypochlorous acid formula that eliminates pathogens on contact — bacteria, fungi, mold, mildew, spores — without leaving residue, without damaging plant tissue, and without touching your trichomes or terpene production. Your plant doesn't know it was sprayed. Your harvest will.

  • USDA National Organic Program Compliant · No PPE Required · pH Neutral · No Rinse Required

— GROWER QUOTES —

"For keeping powdery mildew and mold under control, this product stands alone. It's the ONLY product we use on our valuable plants, and it's the only one we need." — Todd Knupp, Uncle Genes Hemp

"I can't believe I am the only grower posting about this product? I am not paid for my reviews or comments. I use this stuff to eliminate powdery mildew, keeping plants free of disease, etc. I soak seeds in it. I clean all of my tools, reservoirs, lights, irrigation lines, fans, lights and everything else. This product has saved my entire winter crop 2 years in a row! It saved my outdoor crop last season as well. I will never be without it as long as I am a cannabis farmer."

Trashton Porter

"It stopped the mold on contact when we had an outbreak just ten days before harvest. I will never grow without it again." — Tyler Bolton, Bolton Farms

"Works great.!Try it! It’s better than Plant therapy.  It’s not oil like Plant therapy is so you’re not gonna burn your plant like I did. Works great for PM wished I had this years ago."

Brent Ferry

"This Growers Choice saved my crop I was TOTALLY IMPRESSED. Every grower should have this around just in case PM shows up."
