Anyone knows reliable source for stuff like auxin, gibberellin, cytokinin, colchisine?
I'm using powder that contains auxin for rooting cuttings but I consider it short term, as soon as cut area dries out nothing gets inside anymore. So I'm looking for liquids that I can spray on plants or seeds. They are / were quite popular in Indonesia but people there hardly respond to emails....
Try fe looking for IBA (Indole-3-Butyric Acid) in ebay.co.uk (Garden and Patio). The acid itself is not very well soluble, but it's potassium salt is. I use this stuff for rooting several plant species - but so far, have not tried it for rooting cacti.
Thanks robinast. I've done some eBay searching and ended at some yahoo group that deals with hormones or something like that. Will take a look around there and post results..
After quite long online search I finally got where I wanted to:

Name is Erin but you can call him Vincent :) The first (and only) seller that actually 'walks the walk', not only he spent about a week responding patiently to my emails but he tested his stuff on cacti too. If you are looking for auxins, gibberellic acid, cytokinins.. he's the guy you need. Just don't let his enthusiasm gets you or you might end up growing triffids in your GH :)
Anyway, its going to take 'a while' untill I test various stuff I've ordered but I'll keep you posted.
