Springtail question?

[Lija]

Suggestion.
Flood the culture, springtails will float. Then either collect them with a spoon or just dump that water into where you need it to be. You won't be able to transfer all springs, but you shouldn't. Keep it as a master culture, this way you have constant supply of springs. It's hard to kill them, I'm assuming they are in a deli cup, right? Then if you open a lid like every 2-3 days and feed them ( yeast, special mix) they will be alive and multiplying like there's no tomorrow
