eclayne, I've read Julius Boos' article as well and found it very informative. I've never let my johnstonii be exposed to temperatures below 75F. although, it has been a slower grower for me while indoors for the Winter months. I believe high humidity is also a key factor in keeping this plant looking well.
LariAnn, I believe you are right concerning the water temps. I learned this not long after bringing it indoors for the Winter months. I added a small water heater to the tub I had it in and after that it started doing much better. I've also been feeding them with the diluted Miracle Gro solution (as you mentioned for the Synandrospadix vermitoxicus) every three days. The pup has responded tremendously to this and is growing pretty darn fast and even has more leaves vs. my more mature plant.
Wishing you the best on finding a Murksii and my offer will still stand for you on a johnstonii in the future as well.
