Hi Puddin...I have about 450 plants under lights not counting about two dozen flasks. I know I'm nuts but can't help it. Just getting ready to start sowing seeds, have the laminar flow cabinet set up, mother flasks ready and Phal seeds from Newflasker and an order coming from Orchid Seedbank. What are you using for lights? Mine are a combination of metal halide, high pressure sodium, T8s and T5s.
