A couple weeks ago I set up a large (2.5ft wide x 5ft long x 7.5ft tall) grow tent in my apartment for lowland Nepenthes and picked up my exotica plants preorder (~20 plants) from a local nursery here in the northeast. I use an 8-tub, 4ft. long T5 HO fixture, and my light levels and temperature (Day: 80-90, night: 65-70) have so far been ideal.
On problem I have found is that the lighting system seems to really dry out the air in the grow tent during the day. Nighttime humidity is 70-85%, but by the afternoon, humidity can drop to 30-40%. The nursery I got my plants from keeps their greenhouse very humid with a huge misting system (80-99% humidity), so about half my plants are having difficulty acclimating (the other half, particularly my N. (kampotiana x ventricosa) x alata and N. thorellii x aristo, don't care at all and are growing happily). I am planning on getting a small hydrofogger unit so I can set my grow tent to a constant 75%-90% humidity. The hydrofogger I want costs $300, so I won't be able to get one for a couple months.
In the meantime, I am misting my plants 3-4 times a day and watering every day. Should this be okay? None of my plants really look to be declining, just stressed from the move and growing sluggishly. A couple aborted traps. I feel like most Nepenthes can acclimate fine to low daytime humidity well, but about half my plants are bellii and merrilliana hybrids, and these tend to be really picky about humidity.
