    A practical question for experienced members.

    In an unheated greenhouse, speaking generally, what is the lowest temperature highlanders can stand for short periods?

    Thanks

    Howdy there, for highlanders I would say hey could endure a dip down to 35F for a very short period, otherwise they may look like thawed lettuce!

Villosa and Lamii could probably go down to 30F or maybe 28F for a very short amount of time without harm, but leave damage might occur.

    Thanks. So an occasional 38 or so wouldn't do much damage?

    I don't think it would do anything of significant harm but try to stray away from that temperature. The occasional 40F is ok, but getting into the high 30's is pushing it....

    Thanks, Dustin. I think I'll throw a plastic tarp over my fiberglass greenhouse when the weather report indicates.

    Regards

    heyy i think at night your should put the tarp over, because if its sunny during the day itll warm it up the greeen house a bit?

    then at night or liek at dusk throw the tarp over to trap that heat inside

    just a thought?

    Dustin, I got my 40 neps yesterday from Phillip, and they are a mix of vent, grac, and raffle. Last night got down to around 45, and the plants look great. I plan on getting a small heater which I plan on setting to come on at about 42-43, as the idea is that I can use the adult plants in my landscaping business, and I don't want hot house babies.

    I guess the next step is to get the right percentage of distilled water with tap water, and given the tremendous range in local water sources, trial and error would seem the best route to follow. Perhaps flushing out once a week with distilled.

    I'll plan on keeping you informed, and I appreciate your help.

    The gracilis really look great. They're already about 6-8 inches tall, and I watered them in with a hormone/vitamin B mix, and they've perked up from the planting, which was 24 hours ago, and I have enough experiece with plants to know that they'd have shown major stress before now.

    As I'm keeping the humidity high with the greenhouse and misting, do you think that they will fill the little pitchers by themselves within a few days?

    Thanks
