PUREHATCH Nursery Unit
Efficient Nursery for Uniform Growth and Stronger Seedlings
The PUREHATCH Nursery Unit is an advanced pre-deployment system for seaweed cultivation. It bridges the gap between hatchery and full-scale production, enabling growers to produce robust, uniformly developed seedlings for higher yields and greater planting efficiency.
Description
Our nursery solution is based on patented technology that involves fluid-driven rotation to optimize early-stage growth of seaweed on seeded substrates such as twine. Each unit includes a cultivation tank equipped with multiple rotating spools that continuously expose the seed-bearing substrates to a dynamic water flow and to even lighting – thanks to our patented light module.
Rotating cultivation spools: Powered by airflow, the rotation ensures 360° exposure to light and nutrients, improving uniformity and seedling quality
Multiple substrate options: Twine, mesh, film or natural fibers — easily mounted on spools to suit different species
Patented light module: Energy-efficient exposure to maximize growth without heat stress
Improved water movement: Rotation promotes gas exchange, nutrient delivery and fouling prevention
Proven functionality: Proven performance with Saccharina; applicable to Ulva, Palmaria and more
Installation-ready: Delivered as a ready-to-run system with minimal setup
Your Benefits
By rotating the spools and increasing seedling size before deployment, the VALUEFARM Nursery Unit helps secure a higher establishment rate and yield in full-scale farms. Compared to static or manually turned systems, it delivers:
Improved spore distribution and adhesion
Better uniformity in seedling development
Reduced manual labor and fouling risk
ROI < 1 year, based on system prices measured against cost of seeded twine
Enabler of new species through better early-stage control
The Nursery Unit is especially valuable for farms expanding their hatchery capacity or targeting new species requiring more delicate pre-cultivation. It can also support commercial nurseries providing seeded substrate to offshore or nearshore operators.
Ideal for:
✓ Nursery-stage outgrowth
✓ Optimizing twine-seeding
✓ Growth optimization
Best suited for:
Research
Seaweed Hatchery
Why choose it:
Designed for uniform light & flow with rotating spool system
Air-driven rotation minimizes complexity and energy use
Increases seedling success and end-yield potential
“We believe this concept holds strong potential for the future of seaweed cultivation. Spore quality and early-stage growth are critical to the final product, and with this technology, we achieve uniform, well-distributed settlement across the entire surface of our cultivation spools.”
