Here are all my plants nestled inside for the winter. I only have one good window, which is a sliding glass door which faces south, and as you can see, I'm out of space at that window
Those big Catts in 8 inch pots and a couple others you can see kind of behind the racks (they couldn't fit haha) I think are too far from the window to get enough light, so I've been researching growing under artificial light. I have a table in my apartment which I could use for orchids, and I'm leaning toward LEDs. It seems that they've come a long way in the last few years, and some people are having success using them. You guys have any thought?
Just a funny side note, I have found that the most comprehensive and thorough information I can find regarding growing plants under artificial light comes from websites dedicated to growing marijuana indoors

But if it works for them, it could work for me too (with orchids, I mean. I'm not about to risk cultivating marijuana, especially considering how harsh the penalties are in Oklahoma lololol)
By the way, this is one of the specific light fixtures I am looking at:
Amazon.com : VIPARSPECTRA Reflector-Series 900W LED Grow Light Full Spectrum for Indoor Plants Veg and Flower : Patio, Lawn & Garden
Any thoughts on that?
