Aimee, I too am a little leery of that pot. I don't see the practicality of it and you sure don't want a catch-saucer staying full of water. Just stick to tried and true orchid pots.
No, I don't grow orchid from seed. I would have to have perfectly controlled growing conditions and an almost sterile laboratory set-up to do so. I neither have the facilities nor the experience to do this. I will let the commercial growers and the pros grow from seed or tissue culture. I buy my orchids after a year or two growing, and though still tiny, they are more manageable for me.
