Thanks, Richard. I hadn't thought of measuring the humidity but I do have an extra weather unit and can put the outdoor sensor in the pot very easily. I was figuring I would just watch for droplets of water on the bag to gauge excess humidity, but the sensor will be an easy method.
I plan on being very careful on the watering for sure.
This new banana is sitting right next to a Logee Dwarf Ladyfinger I bought a couple of 6-8 weeks ago. It has 6-7 new leaves since I got it and doing very well, though it does show signs of low humidity. That's what gave me the idea of making the tent.
The plant does have it made in my house as we keep it warm since I get natural gas for free (for my house only). People have suggested on adding a sunroom onto the house but I haven't quite figured out where I could put one. Then I'd have to talk my wife into it.
My orchard soil is high in P and I put K on in the fall, so I mostly fertilize with N during the growing season. I have plenty of bags of various fertilizers, though. My other bananas have done well on the combination of fertilizers I've used, but I have not been very precise with these things I'll readily admit.
Thanks again,
Harvey
