VEGETATIVE LIGHTING

6500K LED grow tube: the growth light your seedlings and cuttings have been waiting for

Young plants are unforgiving. Too little light and they stretch into leggy, fragile stems; too much heat and they dry out before rooting. This BloomLED horticultural LED tube delivers a cool 6500K spectrum calibrated for the vegetative stage, at 2.4 µmol/J efficiency and with fully passive cooling. Available in 60 cm (20 W) and 120 cm (40 W), it mounts above your propagation trays, cuttings or mother plants in seconds.

What makes this tube a serious propagation tool

🌱 A 6500K spectrum built for growth

Cool white 6500 K mimics a bright spring sky — precisely the cue seedlings and cuttings respond to. The result is short internodes, dense foliage and stocky stems. Your plants stay compact instead of racing towards the light.

⚡ 2.4 µmol/J means every watt works

At 2.4 micromoles per joule, this tube converts electricity into photosynthetically active radiation (PAR) with real efficiency. Run over an 18-hour daily photoperiod, the gap against an old T5 fluorescent shows up directly on your energy bill.

🔇 Fully passive cooling

No fan, no moving parts, no noise. The aluminium heatsink dissipates heat naturally: nothing to clean, nothing to fail, and a stable ambient temperature above your trays — which matters a great deal in a closed propagator.

💧 IP65 rated

Dust, humidity, watering splashes and misting are all handled. You can water and fog without a second thought, including inside sealed propagators or high-humidity greenhouses where standard fixtures corrode.

🔗 Chain up to 10 units

A single power lead feeds up to ten tubes in series. Ideal for kitting out a multi-tier shelving rack or a propagation wall without a forest of plugs, adaptors and extension leads.

The 120 cm version matches a standard propagation tray or vertical growing shelf almost exactly. For a dedicated cutting chamber, run two chained 120 cm tubes per tier — you get an even light blanket with no dark corners at the edges.

Frequently asked questions

How far above the plants should the tube sit?

For seedlings, hang the tube 15-20 cm above the canopy. For freshly stuck cuttings, stay at 20-25 cm through the first days of rooting, then lower it gradually as the root system establishes. Plants stretching upwards are asking for more light; foliage that bleaches or curls means the tube is too close.

How many hours a day should it run?

The reference photoperiod for the vegetative stage is 18 hours on, 6 hours off. Some growers push to 20 hours a day on seedlings. A basic mechanical or digital timer is all you need — the tube handles daily cycling without spectral drift or premature dimming.

Can I use it for flowering?

This tube is a growth fixture: its 6500 K spectrum is blue-rich, which drives leaf and root development but is sub-optimal for flower induction. For bloom, move to a warmer full spectrum (around 3000 K) or a dedicated full-spectrum LED. It remains excellent as supplemental lighting or for keeping mother plants in veg year-round.

What is the difference between the 60 cm and 120 cm models?

The 60 cm draws 20 W and covers roughly 60 x 25 cm; the 120 cm draws 40 W and covers around 120 x 30 cm. Efficacy (2.4 µmol/J) and spectrum are identical, so the choice comes down purely to the geometry of your space. Both versions chain together freely.
