| I don't recommend time release unless you have a TDS meter to check on how well it is working. How do you know when it is used up. How do you know how much to really use. How about the problem of it disappearing into the pot, and you forget which ones got it, and which ones didn't. In general, orchids have very low need for fertilizer, so the little that is left behind after dumping some thru the pot is more than enough.
