Growing Roses Under Artificial Light: A Basement Greenhouse Experiment

I'm building another lamplight greenhouse to expand my study of roses under artificial lighting. Winter cuttings yielded astounding results—several are blooming in the garden now. Failures taught lessons in rooting media, temperature, hardening off, and other indoor gardening challenges. Success hinges on properly balancing lights and taking precautions.

I bought a dormant rose in early March, potted it, and placed it under lights beside my propagating box. By April 27, I cut my first rose of the year—likely the first in the area—grown entirely in a basement without ever seeing daylight until cut. Space is the main limitation; my 3x5-foot setup with 40-watt tubes restricts capacity. A "lamplight greenhouse" is simply a board of lights, not a traditional structure, yet it produces remarkable results.
