Arguably the most energy-efficient lights for growing. High Output T5, T12, and compacts make it possible to use fluorescent lights across all growth phases, even flowering, not only propagation or mothering.

GrowersHouse has a large selection of fluorescent grow lights and compact fluorescents to suit every gardening need. Fluorescent lighting uses substantially less energy than traditional MH and HPS grow lights. Fluorescents are more commonly used for propagating and mothering plants. T5 High Output (HO) tubes, which are the most popular fluorescents for plant lighting, are more efficient than T8 and T12 fluorescents. They are smaller in diameter. The "T" refers to the diameter of the tube in eighths of an inch. T12 has a diameter of 12/8 inch, T8 is 8/8 inch, and T5 is 5/8 inch. Typically, the narrower the lamp, the more efficient it will be.
