I would consider keeping the 600w and adding another 600 to expand your growing area.

Thank you for replying, John. I know you have an extensive setup I am jealous of
. I was tempted to suggest same thing, but don't have current experience. Also, I think for the added area coverage, the energy consumed is only ~200W or so. I thought you had vandas as well?

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
