“I thank you for the product you delivered to me but I don't have experience with these products when I see some of them is got 1% or 4% of IBM I don't remember the letters anyways what it is the differences between these percentage if it was 1% or 4% and what will work for soft wood cuttings or medium or hardwood cuttings example for the plant prod stim root bottle of 25 mg it says on it is good hormone for all cuttings #1 #2 #3 and on the bottle it says # 2 I bought previously from Amazon the same bottle was red and powder was gray. Yours when I received it I looked it was beige and your bottle you sent to me the pro mix powder was 1 % of whatever IBM or IMB don't remember I have to look at it again anyways thank you ,you've got good service I hope you send to me information about your products between pro mix and the others and about what it is the differences between 1% or 4% and if they are both good for trees cuttings .”
