I'm interested in growing some temperate Drosera species and hybrids on the tray method alongside rosetted subtropical varieties, fulfulling their dormancy requirements via. the fridge method. Will temperate varieties "signal" the beginning of dormancy by forming hibernacula in the absence of cold temps, or do I have to trigger dormancy by placing actively-growing plants in the fridge? I need to know when/how to start dormancy so the plants don't exhaust themselves. Also, when the plants are dormant, do I put the entire pot+media in the fridge, or do I unpot the hibernacula and put it in a plastic bag with sphagnum?
