Testimonials

From our amazing customers

I dropped by [SNS] for some 209 a couple months ago and spoke with the owner for a bit. Gotta say the product worked really well. I didn't spray my cannabis crop once this year (first time ever). The no spray allowed predators to establish for my thrips.. I've got pirate bugs, lady beetles, assassin bugs, multitudes of jumping spiders keeping things in order for visitors. Also, the humic acid sample worked very well too, promoted more growth, greened up the plants nicely. Thanks Sierra for really good products!

We have been working with and using SNS nutrients for more than 4 years. We have had great success with their nutrient line and with their ability to customize our recipes, we’ve not only seen an increase in yield, but have saved time and money by not needing to mix the ingredients in-house. In addition to their quality nutrients, the customer service is top notch as well. The team is quick to respond and get our order ready and shipped. I appreciate the reliability and personality of the entire SNS staff and look forward to working with them in the years to come.

Bought this to help get rid of my spider mite infestation on my cannabis grow space. Typically, the mites always came back after heavily spraying my plants with neem oil. I haven't seen a single spider mite since I applied the 209. About to purchase for a second time because I now have thrips.

One of my roses who’s condition has been much improved by your 209 product. It was so defoliated and leggy from blackspot that I came very close to shovel pruning it. It’s now in its second flush of blooms this season—it has never performed like this before.

First time trying DC & I loved it! I started growing a lot of veggies at home & there is a lot of humidity in my area so my seedling were having a lot of issues with fungus. DC got rid of powdery mildew and the white fluff over night! Love this product!

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!!
