how do you get springtails out of cultures?

I use the flooding method, but also just put handfulls of the substrate from the spring culture directly into the vivs. It all depends on what you are using as a substrate in the culture. I'm culturing on coco husk chips, sphag, oak leaves, and fine charcoal so its easy to put it straight into the viv. You could just dump the whole culture in there, but then you wouldn't be able to make any more.
