Greenhouse # 2 then? he he HL and LL?
My Grow/Want Lists
-The horticulturalist formerly known as Shortbus-
It seems like most growers are overly concerned with humidity. Understandably so, as there is a long established culture of needing to provide super high humidity to grow nice plants, but that is simply not the case. Most of my Nepenthes grow in 35-40% humidity year round. I provide higher humidity for select plants such as cuttings, new aquisitions, small sensative plants, helis, and my smaller lowland neps; but even my larger lowland nep setup (including N. bicalcarata and ampularia) currently only has 40-50% humidity durring the day, and up to about 60% at night. The larger lowlanders grow a bit slower than they might otherwise, but they have acclimated and they still grow fine. Need proof that you don't need high humidity? Here's a few pics of some of my plants growing under these conditions (not to show off, but to prove the point):
N. spectabilis x aristolochioides
N. maxima 'tentana'
N. truancata 'pasian'
Higher humidity does have its benefits, and it will help your moss out, but I personally wouldn't think it worth the trouble or money. I think your humidity levels are within a really good range as is (much higher than for most of my plants, at any rate). Periodic moderate humidity drops will also help to prevent fungus attacks, as opposed to super high humidity all the time.
Obviously not telling you what to do, but just some things to consider.
I guess you're right. Maybe I better just order the thermostat for $20 and spend the rest on plants. #1 on my list is ordering a long awaited lowii x campanulata from Tony.
I sympathise with your concern for the moss though...
If it is watered from above frequently enough the moss should still do pretty well, and the moss in trays should stay pretty wet and humid I imagine. You could partially cover the moss trays with syran wrap? You might also consider hosing down the floor of your greenhouse twice a day with normal water from your garden hose. That would probably help a lot if done right before/durring the heat of the day. I always try for the cheapest options first
Edit: Honestly, I've always thought the sphagnum in your nep pots looked great! You're doing something right!
I found the website I mentioned earlier, http://www.mainlandmart.com/foggers.html
Which one do you guys think would be the best for my GH? I can just purchase a timer and modify the timing as the seasons change so that it turns on during the hottest part of the day, that's what I have done with my swamp cooler.
I'm feeling this one...
5 disc mister fogger, indoor/outdoor transformer(120V/24VAC, 8.33A), 32' long cord from transformer to fogger.
Shipping included in USA.
Again, not my expertise, but I wonder how well most of those ultrasonic units would humidify a larger space like a greenhouse? I think you'd need a pretty substantial one with high fog output, especially if you'll have the swamp cooler running at the same time (which I assume you will). You might want to ask Mass. I know he uses a fogger for his indoor greenhouse.
