Awesome thanks! (Grabs lab coat and goggles and sets to work on my mad scientist laugh. Muah haha haha!) Would you only apply before collection or after collection as well?Indole butyric acid as a potassium salt (IBA-K) and buy it online at a random plant laboratory supplier. I think there are a couple selling to non-business customers.
0.5 mg/L is a high concentration, so you don't need to buy much.
NAA as a salt with acetic acid (NAA-Ac) would work as well.
