Chelle, I have done wintersowing in those translucent gallon jugs for years (I buy water in those,not milk, so no need to clean them) and I know how lovely it is! But with your vermiculite process, don't you have to make sure there is enough headroom by up-potting sooner? And, in the shade, eh? Interesting!
Anyway, I love checking on my babies in the spring: Oh! This sprouted! And that! Oh!
But when it comes to it, who knows what I'll get up to.
Thanks, Allison, for thinking of me -- I found Cocotek online last night and was doing some comparison shopping. I think for right now I am going to go ahead and get some coir from Gardener's Supply. They advertise that they rinse it so the salinity is not an issue.
When I was looking into the offerings on Amazon, though, I was reminded about Azomite (a mineral amendment I've never used but heard great things about.) Anyone here have experience using it?
