Sorry if I confused anyone over IAA and IBA.
It is the Wilsons Root Gel that I am using which is IBA .
I dissolved a 50 ml bottle,
and made it up to approximately one liter in a shampoo bottle.
I think the IAA is the chemical component of that spray for tomato blossoms.
Both IAA and IBA have been used to treat seeds. They are very similar.
