You usually soak a dry rooted orchid for about 10 minutes in a container with a few drops of superthrive to help the roots come back. Two hours is a rather long time. It may be advisable to hang them upside down in a well ventilated area. You might even use a fan to help them dry quickly. Depending on who you ordered from, you may want to send them back if they do not look healthy. There are posts on here about sellers on Ebay. If you bought your plants on there, you might want to send them back fast if you feel there is something wrong or you may be unable to get a refund.
