It grows at 2500 m in Andes, temp is never higer than 20 C but often drops to near zero( +4-+5c), humidity is always high, almost 100÷ and roots are always standing in flowing water from rocks.Not an easy species.
Nice work on the save, and the spike! Another vote for letting it flower, but only if you’ve sorted the heat issue. The best practice would be to cut but if you address the cultural issues I think it would be fine. A basement w LED lights would do it. The right conditions in my basement make me look like a competent grower, but really cool temps and good water makes it dead easy.
