    hehehehe the silicone was on sale!!

    Yep, the slack pot is very similar, both nested pots but with different goals.
    His outer pot is described as being plastic by Barry Rice. The purpose was to provide improved moisture control for the soil mix.
    Cooling would have been a secondary benefit.

    So I guess its a zeer-slack pot LOL

    Nice zeer pot you got there!. How often do you add water in the worst case scenario?

    More suspected than expected. I guess combining it with recirculating solar pump setup and a larger container with water would make it last longer outside.

    Is the temp. drop you are seeing sufficient for darlingtonia? Sorry i dont grow these and know next to nothing about the requirements.

    actually, I think it will be fine as is as long as I don't put it in the bed of my pick up truck lol

    I don't know what to expect to be honest, but I do know that my prior attempts at cobras have resulted in slow declines.
    They just don't seem to be able to deal with the occasional +100f August heat.

    I'm hopeful this will be enough, we will see :-)

    Some friends in Texas have had successes with the plants, by refrigerating the RO water and occasionally applying ice cubes to the compost during the hottest times . . .
