Sigma chemical company sells it and that's where we buy it for our tissue culture experiments. http://www.sigma-aldrich.com/saws.nsf/SigProducts?OpenFrameset It's difficult to buy it from them if you're not a part of a university or a business. You can also check out greenhouse supply companies in your area. There's a product called Pro-Gibb that is sold to spray on azaleas to help them bloom (holiday pot crop kind). It helps to compensate for a cold treatment and reduces time the azaleas need to be in the coolers. You may want to see if a local greenhouse that grows some azaleas can give or sell you some from their stock of it if you need only a little.

David Zlesak

Rick,

Pro-Gibb is also sold at Ag Supply places. Used for grape cluster elongation, promotes flowering in some seed crops, etc.

Hi, You can purchase it from J.L. Hudson seedsman in cal. and it cost $5.00. The spray on acid is mixed in alcohol and can kill the seed.It is dangerous to work with. Some people report sucess with just soaking the seed in H2O2. Delores

A product called SUPERPLANT contains gibberelic acid and is sold in an 8 oz spray bottle for 4.95 by charleysgreenhouse.com They have a great color catalog and it`s free!

Have you checked at the Super K-mart? I've seen them being sold a month ago.
