Gibberellic Acid Solution?

Does anyone know a safe ratio of gibberellic acid (grams/liter) for use on cactus seeds? I have one gram of the powder. I plan on using this on some Opuntia ficus-indica seeds. I don't want to get too concentrated a solution, because that'll harm the seeds. If I have it too low, it won't have any effect. This much I have gathered about its effects (If I'm wrong please correct me).

Hopefully someone will be able to give me a ratio safe for use on cactus seeds in general.

I guess I'll just use the gram in a gallon of water. I suppose that's diluted enough. Hm, with my luck at germinating cactus seeds, that'd probably etiolate and kill the whole batch of seedlings.

Ah well, I might as well give it a shot. What I don't use, I will spray on the dead patches on my lawn. :)

RE: Gibberellic Acid Solution?

While I don't know the right proportions of Gibberellic acid to use, I do know that you may be able to coerce your cactus seeds to germinate with the effects of GA using electricity applied to the soil in which it grows.

That's shocking!
It sounds very unusual and interesting, and I'll have to look into it.
Thank you!

I just found that most users will add one gram of GA per one liter of water, but some just halve the gram. So, I think just treating half of the batch of seeds in a gram per a gallon for a day or two might be safe enough.
