Tyler, it's quite normal for magdalenae to produce basal growths. I have several plants in various sizes, and even the smaller seedlings are prone to making small colonies. Yours sounds like it should be approaching flowering size. This species can flower on fairly small plants and doesn't have to get huge in order to be considered blooming size (and even the larger adults I've seen have still been relatively small-growing and compact plants, especially compared with some of the larger members of the genus like sesquipedale and eburneum). They do appreciate fairly high light levels, so what you described should suit it just fine. In the winter you can give it even more light, and full winter sunlight won't hurt it. It will also appreciate cooler night temperatures in the winter if you can provide them (mine easily handle nighttime lows in the low to mid 40s F without showing any sign of stress--in fact, higher temperatures in general seem, in my experience, to be what stress this species out the most). Congratulations on the new leaf and root growth you've gotten from your plant. Although magdalenae's pretty slow glowing, it's an easy grower that's flowers have, in my opinion, one of the best scents of all orchids. You can also find a cultural sheet for this at
Orchid Culture - Charles and Margaret Baker. Good luck.
