I think so. Esp. if you have cool growing hoyas they would be happy. I brought all my hoyas outdoors and they're in a north-west part of my backyard, under the canopy of a couple of fruit trees. They get dappled shade, yet some early morning sunshine and late afternoon sun for a little while. So northwest exposure is good for your hoyas.

Your hoyas look like they are getting enough light, and many hours of it.

Heck. Those will grow good out there! Have you always had this sunroom? And as far as it being high on the other side, get a ladder. I would have them all the way around, lol!! Now your husband (and mine) may not go for that but you can always ask for forgiveness later... That is an awesome room. I'm just moving almost all of mine out this summer for the first time. It looks great there!!!

we just bought this house december of 2011, so this is my second spring/summer with it... i just got into hoyas last year so lighting is a learning experience... i figured they would like it there but i wanted to double check... oh and if i did get a ladder and try and hang stuff on that side, the sun would be too strong for them anyways so its not a big deal that its out of range... (besides that my husband would have a fit!)

So funny imagining someone getting mad about too many plants in a sunroom!!! That's like getting annoyed because there are too many books on the bookshelf! ^_~

Well, I think your Hoyas enhance this already beautiful room very much. ^_^ And I do think this location is a strong one. Your plants have been making very nice progress.
