MarkNature Chitosan Oligosaccharide, High Active Water Soluble Powder for Plants, Agriculture Grade COS 450g (15.8 oz)

For the price it can't be beat & for how much you get it is value. Plus it's also water solubilizing & 90% pure. Can the others claim that? Nope.I use this & a small amount of salicylic acid for SAR uses every other week. It's great for foliar & root drench/ molasses teas etc..Harpin Proteins work just a tad better for inducing SAR, I spray that twice per grow- 1 in veg & 1 in bloom after the stretch. Great for Trichomes & Terps.* Chitin & Salicylic Acid (Aspirin) are the main ingredients in the overpriced Advanced Nutrients BFX that does the exact same SAR action. Save yourself some big $$

Dissolves quickly, very stable form of chitosan. Using in hydroponics as a root drench to build “Acquired Resistance” in connoisseur cannabis projects. The only word of caution I would use is to wear a mask when mixing, this product tends to disperse quickly into the air if agitated.

I initially wrote a bad review under the impression I purchased a 450g bag and recieved 100g.After a second look it appears as though I recieved what I purchased 😌Will update after results

Did not say how often to use how many times a week to apply

did not use product had to throw out what a mess

It's a bit grainy but when put in to smoothly it ok, need to more powder fine
