    Typically, about 80-82 F, with a drop for a few hours pre-dawn to about 77-78 F. Evening thunderstorms may bring a drop down to 74, but only for a short duration. This goes on solidly for months.

    Trent, I hope and pray humidity is moderate for the pads to have their full effect on the greenhouse to drop the temperatures, lately nights have been warm in the 60's but no ill effects on the highland species at all. Lately humidity has been quite higher and the pads have been not cooling to their max. extent.

    You should get an aquafog... They work great from what i've heard! plus they raise the humidty, and make fog in your greenhouse! it doesnt make the foliage sopping wet!

    Hi Trent,

    this setup won't work. Evaporative cooling only works as long as water is evaporating, i.e. relative humidity is low enough. In a totally closed greenhouse humidity will rise to nearly 100% and then no more water will evaporate - and so you'll get no further cooling from the system.

    Cheers Joachim

    Hmm...I have two N. sanguineas, and oddly both have very different growth patterns.

    The clone I bought from Malesiana is still rather immature and green, even though I've had it for almost a year, whereas the matured plant I bought from Cameron Highlands seems to be thriving.

    The climate I experience here in Singapore is similar to what Choong experiences in KL, so maybe it's something in the Malaysian air! [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]

    Many orchid growers around here have sealed greenhouses with pads and fans. They get about a ten degree drop down at the pad end of the greenhouse. Not enough for highland Neps for sure. Because of our humidity here in south Florida, our greenhouse "cools" using convection. The floors are sprayed under the benches, and hot air is pulled out at the apex of the roof. We have a very noticeable stratification, and this definitely keeps temperatures down during the day. It is quite humid and comfortable during the day, but does not achieve the night temperature drop required by highlanders such as sanguinea. I've posted this before: the only way to get temps down into the low sixties-upper fifties degrees F at night would be to use a refrigeration adaptation.
    Of course, the advantage we have here is the chance to grow specimen plants of the giant lowlanders-our bicalcaratas and merrillianas are just starting to kick in... [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    I have a friend from the UK that said the same thing about evaporative coolers that Joachim did, though most of the US growers endorse them. Kind of odd coincidence, lol. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/confused.gif[/img]

    Cheers,

    As you can see the leaf and pitcher size is increasing now that they are in more suitable conditions. That pitcher is about 13cm (5.1").

    Wow thats a nice sanguinea!
