Subject: Re: Re: GA3 in seed germination
My only hesitation with dissolving GA in ethanol and then mixing in water
would be the GA precipitating out of solution. Since your using so little
you may not see it, in which case you might as well just use water.
Needless to say, if you use alcohol of any kind, use very little.
Any chemists out there?
Regarding Ph, you're always safe around 7 give or take.
We have very basic water here in Tucson and all my plants do well...
.except that one protea.
