Consistency, speed, and quality have become the three cornerstones of successful greenhouse production. Chrysanthemum growers facing a dual challenge: ensuring uniform rooting during the cutting stage and maintaining vigorous growth and flowering during the maturing stage.
We were blessed to cooperate with a Chrysanthemum farm in Japan, the Owner Tanaka Misako told us her chrysanthemum was facing problems:
- Inconsistent rooting: Cuttings under plastic covers often showed irregular development, with some plants lagging behind.
- High occurrence of "blue cuttings": Poor light penetration and fluctuating humidity created uneven, weak seedlings.
- Unpredictable flowering times: Seasonal dependence on natural daylight made it difficult to meet market schedules.
- Yield instability: Production output varied between batches, with an average yield lower than industry benchmarks.

Stage 1: Rooting and Cutting Propagation
The propagation phase sets the foundation for the entire production cycle. Uneven rooting or poor-quality cuttings can result in growth delays and lower yields. To address this, our Clone LED 18W T8 tubes have been specifically engineered for use in multi-layer propagation racks.
Hig PPF (Photosynthetic Photon Flux): Each tube delivers 36 μmol/s, ensuring sufficient light for uniform rooting.
Blue-Enhanced Full Spectrum (77% Blue): Promotes strong root initiation, compact morphology, and early leaf development.
Low Heat Emission: Maintains a stable microclimate in enclosed propagation rooms without overheating sensitive cuttings.
Uniform Illumination: Slim tube form factor ensures even light distribution across trays, eliminating shaded areas.
Daisy Chain support: It offers female port and male port for users DIY daisy chain. Supplies a more uniformity light source.
Tanaka Misako report that with Clone LED tubes, cutting survival rates increase by 12–15%, and rooting is achieved 2–3 days faster compared to traditional cutting method.
Stage 2: Vegetative and Generative Growth in Greenhouses
Once transplanted into the greenhouse, chrysanthemums require a spectrum that drives both vegetative growth and uniform flowering. For this critical stage, our HLEDTLR 1000W fixtures equipped with the R85G5B5FR5 spectrum deliver unmatched performance.
High PPF: Each fixture outputs 3200 μmol/s, providing deep light penetration across dense chrysanthemum canopies.
Red Dominance (85%): Maximizes photosynthetic efficiency, accelerating biomass accumulation.
Balanced Blue & Green (5% + 5%): Maintains compact architecture and improves canopy penetration.
Far-Red (5%): Supports stem elongation when needed and promotes synchronized flowering.
Daisy Chian Support: It support daisy chain when applied in greenhouse, with extend wire to connect the male and female port.
Precise Light, Longer Bloom
In addition, growers can strategically extend the photoperiod by switching on the HLEDTLR fixtures for 2–4 hours after sunset. This supplemental lighting has demonstrated significant benefits:
- Faster vegetative growth with crop cycles shortened by 5–7 days
- Improved uniformity across flowering batches
- Earlier flowering initiation, enabling precise scheduling for market demand
- Extended flowering duration by 7–10 days, increasing vase life and market value
Most importantly, yield improvements are tangible: under conventional greenhouse conditions, average production reaches around 180 stems/m². With our supplemental LED strategy, growers consistently achieve 210–220 stems/m²-an increase of 15–20% in marketable yield.
By optimizing all light and climate conditions, the chrysanthemum greenhouse successfully achieved high-quality, uniform cutting seedling production and shortened the cultivation cycle, thereby achieving its production goals with greater reliability and efficiency.
