Kickstart Vigorous Growth with Mojo Cow PS-1 8500K Purple T5 Replacement Lamp The Mojo Cow PS-1 T5 Replacement Lamp (Purple 8500K) delivers a violet-rich spectrum engineered specifically for propagation and vegetative growth in hydroponic and indoor systems. Each 24 W tube snaps into the PS-1 fixture’s Click & Lock spine, supporting up to four T5 strips in a standard configuration—or expand to eight with the Long Click & Lock spine. Fully compatible with LED PS-1 modules, this modular lighting solution lets growers combine T5 and LED bars to fine-tune their spectrum for maximum root establishment, leaf vigour, and uniform early-stage growth. Ideal for seedling trays, cuttings, and full-cycle vegetative phases, the 8500K purple spectrum boosts chlorophyll absorption and stimulates lateral branching for even canopy coverage and accelerated crop cycles. Its high-efficiency output lowers energy costs while ensuring stable lumen maintenance through every cycle. Perfect for grow tents, greenhouses, research labs, and propagation racks, Mojo Cow’s PS-1 T5 purple lamp offers reliable, scalable performance.
