Hi,
Thanks for identifying the paphios!!!!!
As far as that thing on the leaf, it's all the same and maybe getting less!!! The plant has a little leaf that gets bigger at this period!!! I can't say the "whit spots" are affecting the growth of the plant, but that is for now, I don't know what happens in the long run...
The plant is grown indoors on a tray...
Which plant of the three pictured has the bumps?
I had a 4N lowii with something similar, though the bumps were in much fewer numbers and I was told it had to do with the plant being 4N, perhaps - you know, we get pimples on pouches with polyploidy...just a thought.
I would like to ask two questions:
1. Does anyone know the characteristics of artificial lighting conditions for paphs? (fluorescent vs bulbous lights, spectrum (in kelvin) e.t.c) (I know that it differs in between the species but there should be a general guide...) For example are "grolux" ok for paphs and does the power (in watt) affect plant's growth?
2. How can I promote root growth in paphs?
Also could someone tell me what ""s/h"" is? I've seen it many times in the forum, but haven't found what it means...
My experience with lights has been that just about anything works for Paphs. Generally the multi florals need the most in wattage, but a fluorescent (such as T4, T5, or T8), compact fluorescent (what I use to keep electricity costs down now), Metal Halide or High Pressure Sodium, or even mercury vapor lamps (such as the Wonderlite) have worked just fine for me. Sunlight is nice too.
I think my plants grew best in a combination of sun from a Southeast facing bay window with additional lights (the type of additional lights didn't really seem to matter).
FWIW, your mileage may vary. I have moved four times since April of 2006 and have gone from windowsill growing to basement growing so I've tried it all and the plants still seem to bloom fairly well.
Regarding root growth - you can get hormones such as KLN (which I use to promote root growth). I think Paphs like to be repotted, and often that helps them start active root growth again. Others may have more suggestions there....
S/H is what is referred to as growing semi-hydroponically. See
www.firstrays.com for a detailed explanation. People seem to have varying results with it. I did okay, but found I didn't water frequently enough to promote good root growth from the base of the plant, I only grew new roots from the bottom, down into the water resevoir.
