Collection: Propagation Grow Lights

Propagation grow lights for seeds, seedlings and cuttings

Propagation grow lights deliver low-intensity, close-range lighting for seeds, seedlings and cuttings during their earliest growth stages. Whether you're starting your first seed tray or running an ongoing clone cycle, this range covers T5 fluorescent fixtures, full-spectrum LED bars and E27 screw-fit grow bulbs suited to windowsill setups through to multi-tray propagation stations.

Why propagation needs its own lighting

Seedlings and cuttings grown under weak or inconsistent light become etiolated — tall, thin and structurally weak, with poor root development. Propagation-stage lighting solves this by delivering uniform light at a lower PPFD (photosynthetic photon flux density) than flowering fixtures, typically 100–250 µmol/m²/s, close enough to the canopy to drive strong photosynthesis without stressing young tissue.

What's in this collection

T5 fluorescent grow lights — including 4x55W, 6400K daylight-spectrum fixtures for seedling, cloning and early vegetative stages

T5 replacement lamps — 55W, 6400K tubes compatible with 2-bay and 4-bay T5 fixtures

E27 screw-fit LED grow bulbs — plug-and-play bulbs for standard lamp fittings, ideal for small or windowsill setups

How to choose a propagation grow light

T5 fluorescent vs. LED

T5 fluorescent fixtures are a proven, cost-effective choice for propagation, producing wide, even light with minimal heat at canopy level — safe to hang close to seedlings. LED propagation lights run more efficiently and radiate even less heat, at a higher upfront cost. If you're just starting out, a T5 fixture is the simplest way to get reliable results without a steep learning curve.

Coverage and tube count

A 2-tube T5 fixture suits a single propagation tray around 50 x 25cm; a 4-tube fixture covers a larger area for growers running multiple trays. For windowsill or very small-scale propagation, an E27 LED grow bulb in a standard desk lamp is a low-cost entry point.

Mounting height and photoperiod

Hang propagation lights 15–30cm above the tray and run 18 hours per day. As true leaves develop, gradually increase the distance or step down to 16 hours before moving plants to your main grow light. Even low-heat fixtures can cause tip burn on very young seedlings if hung under 10cm.
