I see they are the only Canadian sourse that sells GA-3. Anyone ever use this stuff to help with seed germination rates?

Thanks, Marie, I'd forgotten about their annual seed sale.

I've never used GA-3. A search on these forums might bring up past discussions on the stuff as I recall a number of years ago some people trying it. Gardens North, and some seed germination sites, will stipulate where GA-3 is beneficial or necessary. I've not yet found the need for anything I've attempted to start from seed.
