TotalGrow™ Stratum 20W Clone LED — 3-Pack, 45", 48 µmol/s per bar

Flexible, Energy-Efficient Clone LED Lighting for Propagation, Greens, and Early-Stage Growth

The TotalGrow™ Stratum 20W Clone LED 3-Pack promotes vigorous rooting and healthy growth for clones, seedlings, microgreens, leafy greens, and transplants. Each 45-inch bar delivers 48 µmol/s at a highly efficient 2.4 µmol/J, providing the precise, consistent light energy that sensitive early-stage plant material needs to establish strong root systems and transition into robust production plants.

The Stratum's full grow spectrum and flexible configuration options make it suitable for a wide range of plants and growth stages — simply adjust spacing and mounting height to match the light intensity your specific crop and goal requires. With the included accessories, the 3-pack is ready to deploy immediately across propagation benches, clone stations, and vertical rack systems.

Key Features & Benefits

• 20W at 48 µmol/s per Bar — 2.4 µmol/J Efficacy: Energy-efficient output delivers the light intensity early-stage plants need without the heat stress or energy overhead of higher-power fixtures — keeping operating costs low across large propagation operations.
• Flexible Spacing Configurations: Adjust center-to-center spacing and mounting height to target the specific PPFD your crop requires — from 100 PPFD for unrooted clones and cuttings to 270 PPFD for leafy greens, herbs, and larger garden transplants.
• Full Grow Spectrum for Broad Plant Compatibility: TotalGrow's full grow spectrum supports a vast variety of plants and early growth stages — clones, cuttings, seedlings, microgreens, leafy greens, herbs, and garden transplants all thrive under consistent Stratum light output.
• Ready-to-Deploy 3-Pack Kit: Ships as a complete kit including (3) 20W Stratum bars, (2) linking cables, (1) plug cable, and light hanging clips — everything needed to install and begin growing immediately without additional hardware purchases.
• Linkable for Scalable Coverage: Link additional Stratum bars using included or additional linking cables to extend coverage across larger propagation benches, vertical rack systems, or germination chambers from a single power connection.

Who Should Use This

The TotalGrow™ Stratum 20W Clone LED 3-Pack is designed for commercial propagation operations, indoor cultivators, vertical farmers, and hobbyist growers who need reliable, energy-efficient grow lighting for cloning, seedling development, microgreen production, and transplant establishment. Its flexible configuration options make it equally effective for small home growing setups and large commercial propagation rooms.

Recommended Spacing & PPFD Guidelines

Configure spacing and mounting height to achieve your target PPFD for each crop and growth stage. Recommended configurations: 12-inch bar centers at 6–10 inch height for unrooted clones and cuttings (~100 PPFD). 8-inch centers at 4–7 inch height for microgreens, seedlings, and rooted cuttings (~175 PPFD). 5-inch centers at 3–6 inch height for leafy greens, herbs, and larger garden transplants (~270 PPFD).

Frequently Asked Questions

What is included in the 3-pack?

This kit includes (3) 20W Stratum bars, (2) linking cables, (1) plug cable, and light hanging clips — a complete, ready-to-install package for immediate propagation bench deployment.

Can I link more than 3 Stratum bars together?

Yes — additional Stratum bars can be linked using compatible linking cables to extend coverage beyond the 3-bar kit. The Stratum system is designed for scalable configuration across propagation benches and vertical rack setups of any size.

What PPFD levels does this light system target?

PPFD varies by spacing and mounting height. The system supports approximately 100 PPFD for unrooted clones (12" centers, 6–10" height), 175 PPFD for seedlings and microgreens (8" centers, 4–7" height), and 270 PPFD for leafy greens and herb transplants (5" centers, 3–6" height).

Is the Stratum suitable for microgreens and leafy greens as well as cloning?

Yes — the TotalGrow full grow spectrum supports a wide range of early-growth and production applications including microgreens, leafy greens, herbs, seedlings, unrooted clones, rooted cuttings, and garden transplants. Adjust spacing and height to match the target PPFD for each specific crop.

How does the Stratum's 2.4 µmol/J efficacy benefit propagation operations?

2.4 µmol/J efficacy means the Stratum delivers 2.4 micromoles of photons per joule of electrical energy consumed — a high efficiency rating for a propagation-focused grow bar. For large propagation operations running many units continuously, this efficiency translates directly into meaningful reductions in electrical operating costs compared to lower-efficacy alternatives.
