From our amazing customers
I purchased a house plant from a local store.I didn’t realize it had fungus gnat’s. I wish I hadn’t wasted $14 on stuff that the same local greenhouse sold me. It didn’t work at all and was toxic. I tried SNS 203 It worked great on my fungus gnat’s in my houseplants.
I grew 6 Cannabis plants using only products from Sierra Natural Science. The plants (buds) were large & quite smelly & the trichomes were large & very sticky! I was amazed how big they grew & had others tell me these were some of the healthiest plants they have seen!!
