Water Quality and Dendrobium Cuthbertsonii

[RandomGemini]

I'm currently growing some tilandisia in my terrarium under a CFL. They are right at the top under the fixture and provide shade for the dracula, lepanthes and masdevallia below them. My oldest of the three is growing like gangbusters. I'm primarily concerned that my terrarium will be too warm. I have a dracula Lotax in there. It grows pretty well but these are more tolerant of warmer temps. I have seen the temp in my terrarium get up to 79 degrees, but a quick misting always brings it back down to 73.4 which is where it usually sits.

I'll be in the basement. Den. cuthbertsonii did very well in my previous setup there with temps occasionally popping up over 75 during the day (usually 70). However, it always got down to between 60 and 65 at night, which I think is important.

My house does get that cool in the winter, but not in the summer months. I woke up this morning to find my terrarium at 67 degrees. I may need to set up a second terrarium because I purchased a couple of plants without double checking their climate and I have some hot to warm species and they may need warmer conditions. I'm already in talks with a friend to purchase his exo-terra that's the next size up from mine. His boa outgrew it and he doesn't need it now.

I have one of these, the tag from Andy's says light from shade to bright. Right now I am trying it on slightly higher than phal light so I will try to up it. I have it on a Kool log but right away it was too much moisture maybe for this time of year or too much in general without drying out. I kept it on the log but I only wet the moss daily and do not fill the chamber. Seems to be working so far. The Andy's tag also says keep wet and cool, good water quality a must. I use distilled or rain water.

Mine sits just under the light less then an inch away. Many leaves are purple, which is fine The key is getting temp down to 50f at night and keep the roots always wet, but not the plant or bloom.

I'd like to revive this thread. Anyone still growing these? I have 3 now and are all still alive. It seems like sometimes it's a fine line between too much moisture or too dry. They like it "just right" and I'm trying to get there. I have mine in a dab of s.moss surrounded by clay like pellets. 2 are sitting in a clay saucer while the 3rd is in a small plastic pot.

Yes, I still do and they are doing quite good. Here are pics of two that just recently started flowering.

Ok, no photos accepted or whatever. I now have six different plants, all seem to be fine in an enclosed wine chiller at 22C day and 10C night. Daily watering with rain water.

Thanks DavBis, do you fertilize, if so how often? What media are you using? Thanks in advance.

[DavBis]

I do fertilize about every two weeks, but I do forget sometimes. I usually leave them as they arrive, but when I repot I use sphagnum.
