Seasun, a south window is great, but 5 feet away is too far. You are not giving your phal enough light and it will decline into death if you leave it where it is. Orchids take some time to die, so you'll think you're doing fine, doing ok, maybe not growing like it should. Oh NO!!! What happened to my beautiful orchid???? Here's how where to put the phal figures: phals need about 1000 footcandles of light to grow and bloom. *Outside* at high noon = app 10,000 FC. You are never getting anything near that indoors because of the ceiling and roof of the house cutting off that directly overhead sun. All you are getting is the slanting sun, of much less than 10,000FC. Cut in half by the window glass and screen. Cut in half again *for every foot away from the window*. At 5 feet from your south window you are giving it *100FC or less* by my fairly generous estimate of what your south window actually lets in. In St Louis, I can keep phals *in* a south window with no damage, just far enough from the pane for a shade to slide down. Start moving it closer to the window. The first day move it to about 2 feet from the window. Leave it there a day or two, feeling the leaves where the sun falls on them (if it does). If they are hot, it's too much light, move at least 6" further away. If barely warm or cool, move closer. Repeat above, moving it 6" closer to the window every couple of days til you are at the place where nearer the window = leaves are hot (or it's in the window). There's been a lot of discussion with newbies about how much light to give phals here lately. Mostly newbies wanting to argue for keeping it on an inside wall in a bookcase where it looks great, more experienced growers arguing for more light, LOTS more. Your phal will love you if you do a search for these threads. Use the search function and put in something lilike "phal + light". If you leave it where it is and it dies in 6 months, put it down to needing to learn things the hard way. Actually that's how most of us learned this lesson.

I have four homemade lightstands for gessies. Two bulbs are just fine. I don't grow orchids so I can't comment on their needs. Debbie

My last grow light was way too small. I decided to invest in this. Is it okay? https://www.amazon.com/gp/product/B002JQBQZQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 2'x1' area

Orchids tend to be free spirits when it comes to growth direction. :D This is a terrestrial orchid, so I'm not sure why it would think "down" is a viable option. Admittedly, these seem to favor any direction when growing in pots or hanging baskets, and I have not noticed this type of growth as pervasively when they are planted in the ground.
