All varieties have started fruiting. The Green Zebra has perfectly round, well-striped fruit and is doing well. The other varieties are more pumpkin shaped with lots of ribs.
The Black From Tula seems to be having a problem with Blossom End Rot (BER), although it is in the same Earthbox as the Zebra, so it must just be more susceptible to that kind of thing.
All of the plants are getting very big, and have required tying up to both the cage and external sources. That was to be expected from indeterminates.
The suspected mite problem is now gone after a few days of spritzing with soapy water.
Current temperatures are mid nineties.
