Hello all!

After a long sabbatical of growing orchids due to a big move, I decided to purchase a huge haul of orchids to replenish my collection. Now here I am with a cluster of various orchids at a single southeast-facing window and I'm super excited. I am fairly confident I have done enough research and have enough experience to at least keep my orchids alive, but I want to ask everybody here what I should change to make them thrive.



I put the sun-loving orchids (catasetum & vanda) right next to the window. I have the medium light-lovers (baellara & oncidium) 1 row behind, and finally my phal. in the back. I do have another little table I could utilize, but just haven't gotten around to it.



I use MSU fertilizer, Better-gro bloom booster, and Kelpmax.
Humidity ranges from 61-57%
Temp ranges from 79-73F (day & night respectively)

One area of concern are my vandas. I understand that they need tons of sun in order to bloom again. Even though they are right in front of a southeast-facing window, I fear that they might not have enough sun. The reason I say this is because the lip of the roof tends to block a lot of the mid-morning and afternoon sun.
Should I invest in a supplemental growth light?
I was thinking about using THESE lights if I had to.



What else would you experts change about my setup?

Please and Thank you!
