I recently read in the Carnivorous Plant UK forum about the potential of killing off Heliamphora by irrigating them with too "cold" of water (what, rather than at room Tb?) -- and one grower attributed the death of several of his expensive plants to just that. This is the first that I've heard of any of this, and it seems to go against the very environmental conditions that these plants normally tolerate. Tropics or no tropics, I can tell you from experience, Venezuela is damn cold at high altitudes . . .
Has anyone heard anything about this? The guys in the UK seemed to think this was common knowledge, judging from the number of responses . . .
