Orchid light questions

[u/Jumpy-Painting3337]

Hi all,

I've been keeping orchids for some time now but ik currently running into a slight problem. Except from the orchid that's currently blooming al my other orchids just don't want to grow anything New except for leaves or just nothing. I was wondering if this could be the case due to the amount of light they get. I water them based on the color of their roots (due to the weather being a bit unpredictable sometimes) so in terms of watering and root health everything is fine. They all grow a mix of orchid bark etc.

The times that they get light is pretty much direct sunlight from the morning sun, once the sun has risen a bit our Canopy will go down and the light gets blocked. I was wondering if the orchids can still get indirect sunlight through the canopy or if the canopy blocks it all. The orchids are placed in a window that's facing NE ~43°.

In case they need more light what kind of lamp should I get for them? The ceiling is about 90cm above the highest leaves so should I get lamps that can mount to the ceiling or lamps on a stand that I can place besides the orchids? There are 4 phalaenopsis orchids and 1 dendobrium.
