You need plaster powder or a similar blend, water (distilled or purified is best), deli cups with lids and a stir rod. Springtails US prefers 16 oz cups. (at Materials Required)
Add two parts plaster to the bottom of the cup and quickly stir in one part water. About 2 oz of plaster by volume suits an 8 or 16 oz cup. (at Setup Instructions)
Let it set for one hour or until fully solid. A water layer above the plaster is fine, because the plaster still sets below it. (at Setup Instructions)
Once solid, rehydrate it. Springtails US adds a large amount of water for five to ten minutes with the cup tilted so the water does not lift the plaster, then pours off the excess and seeds the culture. (at Setup Instructions)
Optionally add a small vent hole in the lid with 35 micron mesh glued over it, or use an adhesive vent. (at Setup Instructions)
Water the culture once a week or as needed. (at Setup Instructions)
A plaster culture lasts 6 months to a year or more before the springtails need to move to a fresh culture. (at Setup Instructions)

Frog and Frond finds clay cultures slowly decline and keeping an old one stops making sense around or after 6 months, though some keepers use them past a year or two. Springtails US says a plaster culture lasts 6 months to a year or more. (at Setup Instructions)

On plaster with the optional retainer you can tilt the whole culture and tap the springtails out. (at Introduction)
A plaster culture lasts 6 months to a year or more before the springtails need a fresh culture. (at Setup Instructions)
