Interlux T5 Grow Bulb 2' (6500K) | Vegetative Spectrum

Interlux T5 Grow Bulb 2' at 6500K for Seedlings and Vegetative Growth The Interlux T5 runs a 6500K daylight spectrum in a 2-foot T5HO fluorescent format — the blue-dominant color temperature that drives the compact, structured vegetative growth seedlings, clones, and young plants need before they're ready for higher-intensity flowering light. Low heat emission means you can position these close to the canopy without stressing tender tissue, which matters in propagation trays, clone domes, and multi-tier nursery racks where vertical clearance is tight. LuxStar T5 Compatible Fluorescent for Propagation and Nursery Racks These bulbs are built for direct compatibility with LuxStar T5 fixtures and work with most standard 2-foot T5HO ballasts, making them a simple swap-in replacement for spent bulbs without rewiring or fixture changes. The 6500K positioning makes them a strong fit for seedlings, clones, leafy greens, microgreens, herbs, and indoor houseplant stations — any application where blue-dominant light promotes leaf development, root establishment, and tight node stacking. Compact 24-inch form factor keeps things manageable in small tents, propagation shelves, and dedicated veg racks.
