Bulb. carunculatum

[WaterWitchin]

I have one that's a good four or five years old. Was blooming size when it was given to me by a friend who thought I really "needed" to grow at least one Bulb.

It's been in SH since it arrived. Always used RO water, and fertilize/KelpMax like anything else, etc. Consistently in spring it grows new bulbs, leaves get to almost mature size, then I get dieback of end of leaves on most of the leaves. And it's never EVER bloomed under my culture.

It's starting to really irritate me. I have new growth coming up now, and this is first year it won't be outside but will still be outdoor temps during summer. I think maybe it gets too hot in summer here? What is the temperature range for these (by someone who's successfully growing them) please? And any other thing you can think of that might be causing it? Or its failure to ever bloom?

If a picture would help, I'll add one later today. Otherwise not climbing those stairs again until I need to.
