Strong U.K. rooting hormone

[Fabby]

Hello all,

I'm wondering if anyone might be able to point me towards a industrial strength rooting hormone that is available in the U.K.? I have read some threads talking about "Hormodin 3" but unfortunately, its not obtainable here.

I'm looking for something primarily for Acer cuttings, which I find I get low success with, and also air layering all sorts.

Any help would be much appreciated

Thank you in advance!

Rhizopon is used commercially but you won’t be able to get above 0.25% IBA unless a commercial grower with trade account.
Clonex gel is good but I prefer rhizopon 0.25. - grab it off eBay

You can get IBA powder on ebay in the uk, work out the % you need and add the difference to clonex, or cut it into a commercial powder, ideally one with NAA, although those are hard to come by now. If you can't find a uk supplier, powergrown.com in the US ship to the UK.

You can get IBA-K as a soluble salt from the internet.
NAA too, but it'll need a helper solution (like potassium hydroxide) to become soluble. Potassium hydroxide is pretty caustic and a small amount can offset the pH by miles. So be careful if you plan on using it.
