Propagation Fluorescent Lights | 18W (2ft) & 36W (4ft) Seedling & Clone Grow Light

Low-heat fluorescent lighting for seedlings, clones and early vegetative growth.

Propagation Fluorescent Lights deliver gentle, even light output across the full tray surface — the consistent, low-intensity exposure that seedlings and cuttings need without the heat stress that damages sensitive plant tissue.

Available in 18W (2ft) for compact propagation trays and 36W (4ft) for larger propagation areas and racks.

Key Features

• Low Heat Output — Safe for close placement directly above propagation trays without risk of heat stress or light burn.
• Even Light Spread — Uniform coverage from edge to edge. No hotspots, no uneven germination.
• Two Sizes — 18W (2ft) for compact setups, 36W (4ft) for larger trays and propagation racks.
• Energy Efficient — Reliable daily performance at low running cost.

Best Used For

• Seed germination and early seedling development
• Clone propagation and cutting establishment
• Early vegetative growth before transitioning to HPS or MH
• Indoor nurseries, grow tents, and propagation racks

Is fluorescent lighting effective for propagation?

Yes. For propagation specifically, fluorescent fixtures remain one of the most effective options available — delivering the low-intensity, even light distribution that seedlings and clones require without the heat or cost of LED propagation systems. Simple to run, easy to position, and proven across commercial nursery and hobby grow applications.

Best propagation grow light Australia — what to look for

Low heat output for close placement, even light distribution across the tray, and the right size for your setup are the key factors. These fluorescent propagation lights deliver all three — available in 18W (2ft) and 36W (4ft) to suit compact and larger propagation areas.

What you'll notice

• Even germination across the full tray surface
• No heat stress on sensitive seedlings or cuttings
• Strong early root development and consistent early growth
• Simple, reliable setup with minimal maintenance

Frequently Asked Questions

How far should Propagation Fluorescent Lights be from seedlings and clones?

For seedlings and fresh clones, position Propagation Fluorescent Lights 30–60cm above the canopy to provide gentle, even light distribution without heat stress. As plants develop and roots establish, lower the light progressively or increase intensity to drive stronger vegetative growth. Avoid high-intensity light on fresh unrooted cuttings as this increases transpiration stress before roots are established to supply water.

How many hours of light per day should I run Propagation Fluorescent Lights during propagation?

Run Propagation Fluorescent Lights on an 18/6 or 20/4 schedule during propagation and vegetative growth. Continuous light (24/0) is sometimes used in commercial propagation to maximise rooting speed but can stress some genetics. An 18-hour photoperiod is the safest starting point for most crops and avoids the diminishing returns of continuous illumination.

Does Propagation Fluorescent Lights ship fast within Australia?

Yes — Propagation Fluorescent Lights ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
