Its been getting hotter then usual where I live 105ºF+ and my A/C on my chamber is on nearly all day and the temps are still ok but they're definitely little higher then I'm able to keep them in the cooler months, 76-77 vs 78-79 now.
I've heard of using Dyna-Gro Pro-tekt silicon 0-0-3 to help with better heat tolerance. Has anyone tried this with their highland nepenthes? I'm wondering if this could give aid to those of use growing HL's in desert conditions. I've just got some in to try it out a few neps I have multiples of.
