Smarter seed starting: stronger roots, easier transplants, and less work
The RSI Hydroponic Seeding Trays are commercial-grade floating trays designed to simplify seed starting and improve transplant success. Made from durable polystyrene that resists bacteria and mold growth, each tray wicks water from below, keeping seedlings evenly hydrated with minimal attention. The pyramid-shaped cells prevent root tangling, so plugs slide out cleanly for transplanting with little to no shock. Proudly made in the USA.
Key Features:
-
Commercial-grade floating design: place in a shallow water pool and let the tray wick water to seedlings.
-
Pyramid-shaped cells: eliminate tangled roots and promote stronger plugs for up to 90% transplant success.
-
Reusable build: polystyrene construction stands up to repeated use season after season.
-
Hydroponic or soil use: suitable for floating hydroponic systems or standard seed starting.
-
Made in the USA: built to professional grower standards.
-
1-Year Limited Warranty.
