Does anyone know a good source for IBA and gibberellic acid? I have ordered them from online sources before , but it's been several years and now I can't rememeber where it was and I can't find another source short of ordering reagent grade chemicals from Aldrich or Fisher (very expensive).

I'm NOT looking for Rootone or Dip-n-Grow or other consumer prepared products. I need to formulate my own and I prefer to start with the raw chemicals.

Thanks
