and thanks again for all the information.
I've repotted my phal and I've got an enormous spike with many buds coming in. I'm thrilled.
I did go to a bigger container as it seemed rather cramped in the last one. I also decided to put the outer roots back in the pot. It has obviously been a success.
So now that I've got a little experience I'm thinking I might like another. I don't have a lot of east facing windows so my space is limited.
I've seen orchids indoors in offices and our local library. Does it take a specific type or orchid to thrive in artificial light?
