If your Nepenthes look this good I can only imagine what orchids would do in your greenhouse. Barkeria, Masdevallia, Dracula, Bulbophyllum, Restrepia, Coelogyne, Cyrtochilum, Encyclia, Epidendrum, Phragmipedium, Holcoglossum, Neofinetia falcata, and Pleurothallis would all probably do really well for you. I can only imagine the color and texture diversity...
I had a question for you Paul... I know you had urged me to get some sort of humidification device for my GH to keep the humidity high so my sphag would grow better. Was there ever a time when you had lower humidity before you got your humidifier? If there was, did you notice a big difference in growth of you Nepenthes and sphag after you raised the humidity? I don't want to spend a bunch of money just to have it not work like I would like it to. Somebody on YouTube had a video of their ultrasonic disc foggers in their GH and 2 foggers, a 4 disc and 5 disc, fogged up a pretty large space with a thick fog. They had their for like two years and only had to replace on disc. I was going to get a 5 disc with a floater. Same kind they have. This is what I was going to get... http://www.thepondoutlet.com/home/tpo/page_3404
You're probably the most knowledgeable person I know about this stuff. Thoughts?
Love that N. (lowii X veitchii) X boschiana!!! It's at the very top of my wish list!
Last summer I did take one of my no-name maxima hybrids outdoors and hung it in a tree for the summer. Our summer air is quite dry, rarely better than 25 or 30%, which is pretty darn dry. How did that Nepenthes do? It grew loads of big healthy new leaves and it flowered twice.....but it never made a single pitcher all summer long. When it was moved back into the greenhouse in late September, it resumed pitchering almost immediately. That was no coincidence; Nepenthes need consistent humidity to pitcher properly. You might be able to get away with 50 - 60% humidity if its consistent and doesn't drop below that, but the dry summer air in the PNW was clearly not to its liking.
As for your pond foggers: I can't comment on how well these will work. I guess you will be the pioneer for the community's benefit! ;-)
Nepenthes lowii, BE clone (Trus Madi), a slow grower, as we all know, but making beautiful pitchers!
