First batch - same as you, where I didn't stir the compound enough. Got some Bondo fiberglass resin and that works great, although the fumes aren't fun. I just ordered some clear stuff (the craft stuff at Michaels works great but is on the pricey side).
My wife and daughter are sensitive to crystal energy so I use them to pick out the best ones. The ones I made are just as strong as the ones we've ordered in the past made by others.
One test I'm going to do is test how orgonite affects sprouting. So far I like what I see.
