Can you tell me which need cool fall outside?

[mimigirl]

I am trying to make new name tags for my orchids with 'cheat sheet' info on them. I am finding conflicting info on which varieties need a cool snap to encourage blooming. Also, plastic pot, clay pot or basket pot? Here is what i have: max tenuifolia, miltonia, ceratostylis, dend unicum, aeranthes, encyclia cochleata, oncydium, brassovola (blc). I know this is a lot, but i only trust you guys since google gives differing answers and I know i cant be the only newbie who might need to know. Thanks in advance!
