I grow my Heliamphora in the greenhouse. Although I do frequently put the Heli's outside for the day, I keep them inside the greenhouse during the hottest, driest part of summer, just to be a little gentle on them while I'm learning about them. Matt sends me unhardened (unaccustomed to natural conditions) heliamphora just out of tissue culture, and those I grow inside under artificial light for some months, until I think I can introduce them to greenhouse conditions.
In both cases, like Matt, I use a growing mix that is airier and faster drying than the Venus Flytrap mix. In my case, I use a coir (coconut husk pith) mix with sand and orchid bark for the greenhouse, sand and perlite for the artificial light environment to compensate for the fact that the growing medium dries more slowly under the LED grow lights in an enclosed room with only slow ventilation.
