Yes but not in any environment. It's windy, temp. around 10 C, pots are in
low level of water with air humidity around 55perc. and they get sun (when
there is) for about 6 hours a day. You now all.

My idea is that you need all these parameter especially for us who grow
saaracenias in "extrem" condition. It is true for pygmy droseras. They go
dormant in summer with hot and dry wheater. On my island summer is hot but
wet and they don't go dormant if don't dry them, they just rot.
I feel like you about the fridge. I think the plant won't really like it and
after it will be hard to obtain a full adult size plant with a well
developped root system. For Cliff his plants didn't die before the third
year (I think it's more because of salt than heat), why not trying outside
at first?
Anyway, good luck.
