Grow them inside under lights or on a sunny window sill. They want a lot of light. They like to be close to growlights depending on the model. Pygmies don't seem to require highland temps but genenral room temps 65-78f suit them well for growth. They can grow outside in the spring and fall provided there isn't frost. Try to grow species and hybrids that don't require a dormancy and can grow in room temps year round. eg. D. pulchella, D. scorpioides, D. pygmaea, D. occidentallis etc. These and more can be grown like D. capensis, although they like it moist, not sopping wet or sitting in water, and they are better suited to house humidity than terrerium humidity although they would enjoy a pebble tray(Shallow water not touching the pots) especially when heating or cooling is blowing full blast and lowers the house humidity into the 20's. Many pygmies grow well this way, but without a dormancy and changing photoperiod they won't form gemmae and in some species, flowers, They will still thrive though.
