suggestions on NOID Dend
I recently picked up a NOID Dend (at least, based on the pics on these forums I have deduced as much - actually a Phal-type dend) that is basically a "rescue". 5 bucks, spikes totally degenerate (I cut them right down), little turgor, essentially no intact medium left in a very very small pot for the 2 canes. There were literally more roots that had burst through the drain holes at the base of the pot than were in fact IN the pot. I repotted in sphag with a little bark and foamy pellets, after I trimmed the roots - there were almost no rotting roots - in a slightly larger clay (unglazed) pot it went with a wicked good soaking. Placed it near a partially-blocked south window, ~2 hr unobstructed light and up to 6 with filtered/indirect sun; only been able to manage ~40% humidity.
Since then, the leaves have become very firm, the canes have tightened up and it seems to have taken well because it turned a very bright, emerald green color (canes and leaves) over a week or so. Based on numerous posts here I gradually upped the sun to SE exposure, corner window, getting up to 5-6 hrs of direct sun/day (maybe 2 feet back), at no more than 80F and no less than 66F. Having checked the leaves at the brightest of times, they NEVER got hot; you couldn't even reasonably call them warm. The medium is kept on the dry side of moist; maybe 1 cup (yep, think the meauring cup size) of water every 10 days so far (pot is an ornamental one; has a volume of perhaps 5 cups) and the surface sphag is dry and crispy inside of 3 days while deeper in is cool and moist for maybe 4 more days. The turgor on the leaves is still very high. After this past weekend, the leaves have turned a very deep red; no evidence yet of sunburn (ie no spots etc) but I gather that his is a sign of upper limits of light tolerance and perhaps beyond, so I have moved it to a spot of very bright though mostly indirect light. The plant appears otherwise very robust now but I'm curious if this is on the right track overall (in general) or is there something blatant and obvious that I am missing in terms of basic care??
Sorry for the length but I thught it prudent to include as much info as possible.
Thanks for any advice or suggestions!!
