Favorite Slipper Orchid: Phragmapedium Living Fire
Default Hours of artificial light

The Medical Marijuana people grow their plants with light 24 x 7 for maximum growth. When they want them to bloom they cut it back to 12 hours per day for a few weeks. I now grow my phrags and small paphs with 17 hours per day all year and they love it. The phrags are not photoperiodic and are blooming like crazy. The big paphs I grow in a greenhouse where they get seasonal light. I have 2.5' wide benches with 4 bulb 4' T5 fixtures with two white and two red (3500K) bulbs in each. I also grow plants just out of compot in these conditions and the are growing quickly.
