The yield of the plant was also decent, with 4-6 fruit per cluster and large enough to meet my benchmark of a pound per cluster.
Some weights from my notebook give a range of 66 g to 189 g.
I didn't prune and let the plant ramble on the hopes of more fruit, of course!
Some fruit that were close to the glass (and temperature extremes there) unfortunately split, so this is one tendency to watch out for in future. There is no significant tendency to splitting in the parent lines that I have noticed.
