SUNBLASTER COMPLETE 18″ (45cm) T5 PROPAGATION LIGHT

Description

SunBlaster Complete 18″ (45cm) T5 Propagation Light is a compact, high-output fluorescent propagation unit combining a 6400K T5 HO (high output) lamp with a parabolic reflector and all necessary hardware in a single, ready-to-use propagation lighting solution. We have been recommending SunBlaster T5 propagation lights to UK growers since 2017 as a reliable, proven choice for seedlings, cuttings, and mother plants where quality, full-spectrum light at manageable intensity is the priority during the critical early stages of plant development.

Why SunBlaster T5 Propagation Lights Deliver Superior Results

SunBlaster’s proprietary NanoTech T5 lamp technology produces a high output relative to lamp wattage, delivering more photosynthetically active radiation per watt than standard T5 fluorescent tubes. The 6400K colour temperature provides the cool blue-dominated daylight spectrum that promotes compact, dense seedling development — short internodes, thick stems, and rich green foliage are all characteristics of seedlings raised under appropriate blue-spectrum propagation lighting. The parabolic reflector included with the Complete set is designed with SunBlaster’s unique reflector profile that focuses output downward into the plant canopy rather than allowing light to escape laterally, measurably improving the usable PPFD at canopy level compared to the same lamp in a simple flat reflector. The 18-inch (45cm) length is matched to standard propagation tray widths, and the complete unit can be used as a standalone light for a single tray or connected with other SunBlaster units via the LightStick Connector for wider coverage.

How to Set Up and Use the SunBlaster Complete 18″ T5

Hang the SunBlaster Complete unit above your propagation tray using the included hanging hardware, positioning 5–15cm above the top of your propagation plugs or cuttings depending on plant sensitivity. Run on an 18–20 hour timer for cuttings and seedlings. The T5 lamp runs cool enough to position close to sensitive young plants without heat stress risk. Connect multiple units via the LightStick Connector system for full shelf coverage without additional wiring. Replace the T5 lamp after 8,000–10,000 hours of use as output degrades, affecting propagation quality even when the lamp still illuminates.

Pair the SunBlaster Complete T5 with a propagation tray and dome, heat mat, Clonex rooting gel, and Formulex starter nutrient for a complete, high-performance propagation station. Browse our full propagation range for all the equipment needed from cutting to transplant.
