When do cyms start initiating growth spikes?

[Kailyn]

Hello
I got 2 NOID cyms this summer out of bloom. They have both bloomed before as I see evidence of old spikes. Assuming they are happy and healthy when can i expect spikes? They both have 2 of this years growth which isn't fully developed yet. I also wanted to know if to encourage root growth on them is similar to other orchids (bottom heat and seaweed fertilizer?) I am expecting some root loss due to the media change when I brought them home and repotted but hopefully they pull through quickly.

Different ones may spike at different times - I have one that can start spikes as early as late July, others in Sept-Oct.

If your Cyms had good or better roots, I wouldn't worry about encouraging root growth. If roots were poor, the plants may not spike this year.

In my area, my cyms gets their spikes when there has been a good cool down, usually in mid to late Fall.

cyms generally need a distinct drop in night temps from day temps to initiate spikes. Here in Aus they generally start spikes in late autumn

good to know we've had some strange weather this fall almost freezing temps for a week or so when i brought everyone in then the last week it has warmed up again so my phal whos thinking about a spike and my bigger cym are both back outside. *does flower dance*

As mentioned, depending on the cym.
What kind of cym are you talking about??

I have two standard (large) Cyms that sit out all summer and get fairly good light. I leave them out till close to freezing. We had weird weather a few weeks ago also and I had to bring them in but they are back out again. I have the start of a spike on one but nothing else so far. Last year I had short spike nubs by mid to late summer which rather surprised me. I guess our nights had been cool enough. Mine seem to bloom reliably with that fall chill before I bring them in. I get blooms anywhere from Nov. to Feb.
