this post is a little late but, when I get down to a clear container like the two liter, then I just use a turkey baster to get it down to about a half inch over the hash, then I pour it out on a plate and put it on the top of my oven to dry and evaporate. then I scape that up and roll it into a ball and throw that in the freezer. Whatever works bro. I've had a lot of practice lately. Had 3/4 male plants last crop...
