I think you can, but you really need to almost be a botanist to figure out what those amendments are.
We're going to be working on a project with America's Best that evolves along lines something like what we're skirting around here, and of course, we'll keep the world posted on what is learned, but honestly, I'm not sure that there have been any specific tests of that type done yet...
I'll in contact with some folks who might know stuff like that, I'll ask them and let you know if I come up with any info.
In the meantime, I curious as to what our other growers' thoughts are on the topic.
