## Description

Auxin growth regulator. Substance Name: IAA CAS Number: 87-51-4 Molecular Formula: C10H9NO2 Molecular Weight: 175.2 g/mol

Review: Great soil additive! - IAA in lower amounts, from what I have researched, is great for your beneficial bacterial growth in soil and root propagation. Too much will do the opposite. NOT A CLONING SOLUTION! Get IBA for that. My tomato experiment has been successful as I'd hoped for with the IAA in the soil. Plants grew MUCH faster and the fruits grew much better and larger as well. The beneficial bacteria growth was very visible on the IAA control over the regular soil control. Much fuzzier than the other lol.
Review: The product didn’t come exactly like pictured( homemade labeling ) - It was in a different bottle that looked like it had a homemade label. I did not see any difference in the plants I applied it to. Smells strange when mixed in water like hospital grade sanitizer
