Hmm.. that just gave me a thought. If the plant could survive this way, you could find a magical temp/spectrum combination of light bulbs to inhibit red pigmentations development in the plant.
What lights are you using? kelvin ratings?
I am using a mixture of a T5 and HPS fixtures. The T5 Fluorescent Grow Lights are 6500K and the HPS is probably about 2000K. It is a nice mixture of warm and cool. I use a light meter to dial in the correct height of all the plants from the light, 600-800 foot candles.
I'd love to see a pic of the entire set up Michael. I've been trying to picture it in my head and it's just not happening.
Dang! Great collection you've got there. Love that N. lowii x truncata. Hope mine looks like that some day. I grow all of my Neps indoors as well. What do you use to give your ulta-highlanders a significant temp drop at night??
Ahh your lowii x truncata is nicccee!
Michael, is the edwardsiana the AW clone or is it one of the seedgrown plants from "you know who" (will not mention his name for the same of him not being bombed by emails and requests)
incredible plants man
i hope the lowii x truncata wide peristome turns out great... ive got one that has some good size to it now...
Here is a quick overview of my closet setup. This is for the highland plants.
This is the view looking into the closet. What you are looking at is a GrowLab Grow Box turned on it's side. There is a sheet of poly-plastic on the top that seperates the lights from the plants clipped down with binder clips. This is important cause the lights get super hot, so be keeping the lights outside of the setup I can keep the inside cool. You can see there are three fixtures overhead, two t5 fixtures left and right and then a single HPS in the middle to fill out the spectrum. To the right you can see a window air conditioning unit that I have rigged. There is a funnel made of box cardboard wrapped in waterproof white tape that funnels the air output directly into the chamber. This is how I can achieve night temps sometimes as low at 48 depending on how warm I can keep the window a/c unit. The A/C unit is positioned on a plastic crate overtop of a platic tub that collects access water from the A/C. Also note that the A/C intake which is in the front is positioned outside of the chamber. If it was inside this would probably ruin the A/C cause sometimes the A/C would be sucking in 100% humidity air in. On the floor you can see the timers utilized for turning the lights and the A/C on and off as needed. The truly great thing is that this chamber runs itself.
Here is another important component. On the inside far right of this grow chamber there is an ultrasonic humidifier with a fan mounted on top. The humid mist comes out and is blown horizontally across the grow space. The picture is bad cause this is in the early morning when the lights are popping on and the humidity is 100% at this point. During the day as the chamber heats up the mist inside will burn off an stabilize at around 70% humidity.
This setup took me a while to get right but now it seems to be working efficiently. I can grow any highlander in here with ease and requires little work on my part.
Thanks for checking it out.

@SirKristoff. Neither of those sources.
OMG Michael.. it all seems so.. simple. I didn't think those basic window units produced that low of temps. What about all of the excess water from the humidifier? Where does that go?
hmm.. now I'm really curious to see the entire view of inside the lab.
