Hi, I am new to the forum. I really get into indoor trees but I also have some orchids. I have used a ton of different LED grow lights. Attached are a couple of pics from my living room, the experimental area. The "Grow UFO" type lamps are producing intense fruiting in the miniature orange tree even in the dead of Chicago winter. the real benefit is that you can get them right on top of the plant because of the low heat. With orchids I have only been able to make a plant bloom with red light. Just empirical info but my recommendation is to go heavily towards the red end of the spectrum. Keep in mind a lot of the LED products on the market are geared towards cannabis growers where you are trying to produce more vegetative growth at different times.
