And water... so please, take them out of the water, pot them in a airy material (bark chips is a good example) and water them frequently, at least every day. Give them a good soaking when you do water them, but make sure they can dry off afterwards. If you want to have them really healthy, make a very dilute compost tea and water them with that.
Cold down to about 60F is what tells orchids to bloom. :)
