Omega 2ft Nano Single Tube T5 Propagation Light — Cool Blue Spectrum for Seedlings & Cuttings
Best for: Hobby growers and small-scale propagators who want reliable, low-cost lighting for seeds and cuttings without the fuss
Our thoughts
T5 propagation lights get a lot of stick these days because LEDs exist, but here's the thing — for the first six weeks of a growing cycle, this does the job brilliantly. Cheap to run, barely warm to the touch, plugs straight in. If you're serious about getting healthy seedlings and cuttings without overcomplicating things, this is a solid choice.
The Omega 2ft Nano Single Tube T5 Propagation Light is a straightforward 24W fluorescent grow light designed specifically for bringing on seeds and cuttings. It delivers a 6400K blue light spectrum — exactly what young plants need during propagation and early vegetative growth — without the complexity or cost of larger systems. No ballast, no guesswork. Plug it in, position it above your propagator, and it does its job.
You get proper light coverage for seedling trays and small propagators, low heat output that won't stress delicate plants, and running costs that won't make you wince. This is one a lot of growers start with, and for good reason.
How it compares
T5 propagation lights sit in a different camp to modern LEDs, and that's worth understanding.
-
vs LED propagation lights: LEDs are more efficient long-term, but cost more upfront. T5s still win on initial outlay and work brilliantly for short-duration propagation work. For a six-week seedling cycle, the electricity savings from LED don't add up.
-
vs larger T5 systems: Single-tube fixtures are compact and perfect for small spaces. Multi-tube systems offer more coverage but cost more and take up room.
-
vs no supplemental light: Seedlings grown on a windowsill alone end up leggy and weak. This fixes that completely.
Usage guidance
Installation
Plug directly into the mains — no ballast, no installation. Suspend it 5–10cm above your seedlings using adjustable hangers or sit it on top of your propagator lid. Raise it as plants grow to maintain consistent light intensity.
Light schedule
Run this for 12–14 hours daily. Most growers use 14–16 hours for compact, healthy growth with an 8–10 hour dark period for cellular repair. Use a basic timer to keep it consistent.
With a propagator or seedling tray
Place directly above your propagator dome or seedling tray. The 6400K spectrum is purpose-built for this stage. Once roots have developed and you're ready to move plants to vegetative growth, this light will still work, though you may want to upgrade to broader spectrum coverage.
Daisy-chaining
You can link multiple units together if you need to cover more area — useful if you're scaling up.

Who this is for
- Hobby growers starting their first propagation setup
- Anyone with a small propagator or seedling tray who needs reliable supplemental light
- Budget growers who want proven performance without LED pricing
- Growers managing compact spaces — windowsills, spare shelves, small benches
- Those doing seasonal propagation (spring seedling runs) rather than year-round cultivation
Our take
This is a no-nonsense propagation light. It does exactly what it's supposed to do — deliver the right spectrum at the right intensity to seedlings and cuttings — without unnecessary complexity or cost. T5 propagation lights have been the standard for years, and they're standard for a reason.
If you're serious about getting healthy, compact seedlings instead of leggy, weak ones, this is worth picking up. Cheap to run, reliable, and proven. Good time to buy while stock lasts.
