    Sphagnum ?

    UPDATE on sphagnum: I just checked some Paph callosum, niveum, acmodontum, and delenatii, and all are going gangbusters with new roots.

    UFO Tri-Band LED lights??

    Agreed! I don't want to pay $1600, and I haven't heard anything one way or the other yet about the UFOs. My needs would be longitudinal anyway, only about a meter in depth but 4-5 meters in length. Sounds like a linear setup of fluorescent bulbs (with different wavelengths) could be best ??? V.

    more o chromosomes Hi all: See below some more shots of chromosomes, this time 2 species with their telomeres and telomere sequences lighting up. The top one is Paph moquttianum; the second id Paph dianthum. Telomeres are sequences that cap chromosomes to keep the ends from degrading...

    Any non-aggressive folks interested in discussing taxonomy?

    Different chromosome numbers could be used as evidence for difference between species, but I'm afraid it isn't so easy. There have been reports of different chromosome numbers in Paph wardii, for example, 2n=41 or 2n=42.... and Paph venustum 2n=40, 41 or 42. Now one could claim that these...

    Any non-aggressive folks interested in discussing taxonomy?

    Sorry, my words were a little misleading -- The main loci are the 2 VERY STRONG red sites, and the 2 very strong green sites. Again, these are clusters of DNA that encode two different genes that are principal in eventually making all proteins. By 3 red BLOTCHES, I meant the LESS STRONG red...

    We are working on Fluorescence In Situ Hybridization (FISH) to study chromosomal evolutionary dynamics in the slippers -- very, very interesting so far! You get a lot more information than simple chromosome counts. Check out this image: The blue things are the chromosomes; the red...

    gosh, I had fun here! A NEW QUESTION FOR THE GANG: Does anyone view chromosomes as important for slipper taxonomy, etc? Vic.

    UFO Tri-Band LED lights??

    Do I read right that you find these lamps to no longer be manufactured?

    UFO Tri-Band LED lights??

    Thanks, Shiva: I've seen these specific ads for UFO-shaped lights with triple cooling fans -- both in red-blue-orange and red-blue LEDs only. If you can communicate on the brands you've used, that would be great. Also, how close you allow the ballasted fluorescents to get to the plants, and...

    UFO Tri-Band LED lights??

    Does anyone have experience with these or similar LED lights? If so, how close can they get to plants? Don't they produce any heat? Actually, some would be welcome. Best, Vic.

    BTW, Windy Hill and Oaxaca are definitely different -- I've had both in bloom this month. Plus the foliage is distinct. Best, V.
