Thanks everyone for your advice. I did have a few spikes before this time last year. We are having a pretty cold winter by our standards and the room they are in is difficult to keep warm for them. This is also the first complete growing cycle they have been in ceramic pots. Hmmmmm....? I'm thinking the plastic will get them more light and I, for once, can see what is going on in their little pots!
I always, ALWAYS re-pot when I get an orchid home. I have had too many fade away because of packed sprag or a duel media, and/or rotten roots from the grower. One of the best things about growing in coir is that I do not have to traumatize roots to get the plant out of the pot. I just wasn't certain if there was something cyclic that happens this time of year (winter), spikes or not.
AND....if the truth be told....I can get more orchids under these lights in progress if they are in plastic versus ceramic.
Maybe I will just do some and not others; now that's an idea!
