Hello,

My phal got into trouble this winter: potted in bark, pot raised in huge glass container with pebbles and water at the bottom, the entire thing sitting on a table on the west wall close to a south facing window. Temps were >20°C during the day and ~16-17°C at night. Plant never got direct morning sun. However, with the winter, I don't think it got enough light. The leaves are quite dark and the plant doesn't look good, roots are fine but not too many and I only have a few small leaves left.
Now I just couldn't resist and bought two other phals blooming.

As I said, I think I'm having so much trouble with my phal because of the lack of light. It did much better until winter started. I don't have grower lights, so I'd like to know what you think would be the best placement for the phals:

about >20°C day, about 17°C night:
1. North-east window, just behind the windowsill, on top of radiator, in long water filled plant tray (with pots raised inside the tray). This is my office so I usually have some lights on in the evening in this room.
2. South window, away from windowsill, away from direct sun (same placement as above), with a table lamp beside it during the evening. This is the warmest room of the house.

about 20°C day, about 16°C night:
3. east window, just behind the windowsill, on top of radiator, in long water filled plant tray (with pots raised inside the tray). I can have some lights on at night, not as bright as 4. but second brightest at night of all the rooms.
4. east window, about 1 meter from the window, no radiator underneath the window, this would be the coolest place but the brightest at night (kitchen, pot lights in the ceiling that I could live on)

I don't have a room that have all the requirements at once; all together the best might be 4., but I'm worried that it might be a bit too cool for a phal...so then it would be 3., but then I have the radiator issue.

what would you do?

thanks a lot!
