I'm thinking about buying a few containers (and charcoal) and setting up a few more springtail cultures so I can have way more on hand. The idea is to seed my tanks weekly - my varaderos rifle through these things like nobody's business, and my four terribilis froglets will, too. In order to do this, I want to have a few cultures producing, but at different stages. So culture A will be tapped on week one, culture B on week two, culture C on week three, etc. The question I have is one of timing: how long, based on feeding daily or every other day, do springtail cultures take to bounce back after being tapped into? If it takes a month, then I want 4 cultures producing, which will then be staggered weekly (and kept track of accordingly). Obviously, if it takes longer, then I'll have more cultures booming, since I want to do this weekly.
