I used to be an "Accomplished Phalaenopsis Murderer"!!!! I was on Death Row for a number of years for killing dozens of them!
Then while in Florida I discovered how to grow them. I came up with my Oreo method and things grew great for 7 years!
When I moved I gave them all to my son here in Michigan. I can't fit then underlights. He has a large window area to grow them in. He just had one of mine in bloom from early last December through this December. The final flowers faded Christmas week!!!
He is using the "Oreo Method"!!!! Plastic pots, one third aliflor mix, one third sphagnum and one third aliflor mix. Works like a charm. He waters every Saturday.
Warmth and water, that is the ticket!!!
