Orchids and Gibberellic Acid
I have used gibberellic acid successfully to make orchids re-bloom. A number of people have said that gibberellic acid is expensive. That is true, but the amount that you need is very small. If you buy 10 grams on eBay or Amazon for say, $9.95 that is enough to make gallons and gallons of solution. That is more than you would ever need unless you had a greenhouse full of orchids.
