Catts: Sheaths, no Sheaths in Same Cultivars

[WhiteRabbit]

That is not unheard of in hybrids. I don't know if time of year, temp, light affect this phenomenon ...
I have one hybrid which gets both unifoliate and bifoliate growth, and I have noticed that the unifoliate growths get sheaths, and the bifoliate growths do not

Interesting! The two in sheath right now which, in winter. produce buds without sheaths... are both unifoliates.

See this? THIS....makes absolute sense!

the only item I notice in my short tenure as orchid grower instead of orchid killer is that the sheaths are very thick and many times so far this season I have to rescue the buds bec the spike cant push thru...lost quite a few buds this year bec I dont catch some of them in time.

I would say that hybrids can bloom any time and/or all the time given proper regimen of air water and food....

If you grown them indoors under lights there is no season.

Interesting. I think I've only had to open a sheath to facilitate bud development once. I grow indoors, but with no augmentation of any kind, cept for what I've invented. I plug nothing into any power supply.

Interesting! I have not encountered bud blasting, really, when the Catts in question do what they do in winter, the buds develop normally.

Also true, I just remembered, the bulbs these plants produce in winter are smaller than those they produce in spring. I attribute that to the number of hours of light and also the angle of light.
