I have been gone for 10 days and am hopelessly behind in my "reads". I will never catch up, also having over 500 emails to wade through. When I left, the highs were mid-90's and lows in the upper 70's (and stayed the same for 4 days). A strong cold front moved through the southeast and dropped the temperatures down into the low 50's with highs in the 70's. Wow! When I returned, all the smaller (rooted) plumeria had either dropped all their flowers or their stalks. Only the large, mature plumeria are in bloom. The plumeria that had over 20 seed-pods is now down to 14 pods, and all of them are now pretty large pods, so they should stay. The other two plumeria with seed-pods kept all their pods.
I started providing supplemental fluorescent light about four weeks ago, having the fixtures turn on around 3 PM and then off around 8 PM. I am using T5H fixtures, six tubes per fixture and have 4, 6500 K and 2, 4500 K tubes per fixture. These fixtures are in my greenhouses and I am only using two fixtures in one greenhouse that gets shade from the house around 3:00 PM. The only thing in that greenhouse is Nepenthes and plumeria cuttings.
