Who This Is For

  • You are switching to multi-tier racks because your current single-level setup wastes too much vertical square footage.
  • You are moving away from T5 fixtures because the heat they put off dries out your clones and propagation domes.

What We Found

  • We like using the 18W setting for initial rooting to keep the heat down before flipping to 30W for faster growth.
  • The heat sink is actually efficient enough that you can touch the bars even after they have been running all day.
  • We tell people to grab the two-pack just to have a spare, but the IP65 seals mean they rarely actually need it.

What Users Say

  • Growers who swapped out fluorescent T5s say their clones are sturdier and ready for transplant days earlier.
  • Facilities that daisy-chained these bars say their rack wiring looks much cleaner and took half the time to set up.
  • Users running high humidity domes report that the IP65 seals prevent the internal fogging seen on cheaper bars.

GrowPros Solutions 4ft Clone Bar 18W/30W LED Grow Light - 2 Pack

Struggling with leggy seedlings and weak root development in your propagation trays? The Grow Pros Solutions Clone Bar delivers targeted blue + white spectrum illumination that reduces internodal spacing by up to 40% while accelerating root development in clones and seedlings. This 4-ft LED bar allows you to toggle between 18W and 30W of power, outperforming traditional T5 fluorescent fixtures while fitting perfectly into tight vertical farming racks.

The Clone Bar is engineered specifically for commercial and hobbyist growers operating multi-tier propagation systems. Its low-profile design maximizes vertical clearance, while the integrated aluminum heat sink maintains optimal operating temperatures without adding excess heat to your clones. With an IP65 rating, this fixture is built to thrive in high-humidity environments, and the integrated double-ended connectors allow you to daisy-chain up to 28 strips (at 18W) or 17 strips (at 30W) from a single power source.

Equipped with 144 full-spectrum 4000K white diodes, 24 pure 460nm blue diodes, and 24 far-red 660nm diodes, the Grow Pros Solutions Clone Bar provides a scientifically balanced spectral output. The durable PC cover ensures excellent light transmittance and is easy to maintain. Backed by a 5-year limited warranty and featuring 89% driver efficiency, this fixture provides the commercial-grade reliability needed for high-volume propagation.

Frequently Asked Questions

How many lights can I daisy-chain together? +

The Grow Pros Solutions Clone Bar is designed for high-density vertical farming. You can daisy-chain up to 28 strips when running on the 18W setting, or up to 17 strips when running on the 30W setting. This allows you to cover large propagation racks using very few power outlets.

When should I use the 18W setting versus the 30W setting? +

The 18W setting is ideal for newly cut clones or young seedlings that require lower light intensity to avoid stress. Once your plants have established a healthy root system and begin early vegetative growth, you can switch to the 30W setting to provide the additional energy needed for faster development.

Is this light safe for high-humidity environments? +

Yes, the fixture is IP65 rated, meaning it is dust-tight and protected against water splash or spray. This makes it perfectly safe for use inside propagation domes or in grow rooms where humidity levels are frequently high.

What kind of mounting hardware is included? +

Each box comes with mounting brackets and the necessary hardware to secure the bars to your shelving or rack system. The low-profile design ensures they can be mounted very close to the shelf above, maximizing your vertical growing space.

Does the light produce a lot of heat? +

The Clone Bar is highly efficient and features an aluminum heat sink for passive cooling. At 18W, it produces only 62 BTU, and at 30W, it produces 103 BTU. This minimal heat load is essential for maintaining stable temperatures in multi-shelved racks where airflow can sometimes be limited.
