This plant flowered in the fall of 2015 and 2016 (the first 2 years after import). But it started to flower in the normal time (spring) in 2018 and 2019. I forgot to record it in 2017, or it didn't...

That is very interesting! I lost both of the plants in the original post. Do you know a source for the smaller C. mooreana? I killed 3 from Peruflora, and all of them were the larger form.

It primarily depends on the cost of electricity and how long you are going to use them. Parmida doesn't give relevant specs (even the basic things like lumen output). So I'm assuming that they are...

I'm not sure if I would call it mottled (like P. schilleriana or P. stuartiana), but the leaves have a slightly marbled pattern with deeper green and grayish green. You can see the photo of leaves...

I wouldn't use too much moss on this species. I haven't grown it from flask, but it seems to do better if it is kept drier. So if you do use moss, you might want to remove it after a couple months....

With the stock solution of MSU, CaSO4 is the most likely precipitant. There are more molecules of Ca than S in MSU, so sulfate deficiency is likely to happen. But if CaHPO4 precipitate, then Ca...

That is moderately expensive, so it is probably cheaper to get efficient ones. Even with the low-end LEDs, you are right, there isn't a point of going with T5HO anymore.

If you put it close enough to the leaf (guessing 6"-10"?), the plant will grow. It is pretty expensive, and house-hold LED BR40 or PAR38 bulbs would be probably more efficient and cheaper (no specs...

They last quite a while, and at least >1 week for sure. I don't have C. calceolus or C. parviflorum var. parviflorum, but I'm basing it on C. parviflorum var. pubescens.

You can choose from 3000-5700K. Sunblaster is 6500 or 4100K. The EB strip I linked earlier is 4000K, which would be my choice. In general, 3000-4000K is probably slightly better...
