Growing Heliamphora minor outside in full sun in
Growing Helis is supposed to be really hard to do. Perhaps if you are trying to do so indoors? As much as I would like to try other species I consider myself lucky enough to be able to afford a couple of colonies of H. minor several years ago. My intent then was to grow them outside as I really had no room in my greenhouse for them. And besides from what I could tell from what LITTLE I could find then on their natural habitats I believed that they should be able to make it. So here are links to three different sections of webjournals on my experiences.
The only real precaution I take with them is to move them onto my kitchen window ledge, outside, when the air temps drop down into the 30sF (around 4C) though I think they can handle occasional freezing temps.
