Catasetums waking up

[orchidsarefun]

So much the same has happened this year, except
- my fdk are growing well, even the backbulbs of a while back
- my tabulare and pileatum are in full leaf with no sign of new growth.
I've watered weekly weakly all throughout and this seems to have really kick-started the fdks.
Received an email from Orchids.com and they reported that the polar vortex has had an impact on bloom cycles. Maybe also on growth cycles ?
