Danish Hydro Tray — Ebb & Flow Cultivation Tray

Danish Hydro Tray — Ebb & Flow Cultivation Tray

A classic Danish-style flood-and-drain tray — the most modern cultivation method for pot-plant production, engineered around the ebb and flow principle. Tray is filled with nutrient solution on a timed cycle, plants absorb water through pot drainage, and the solution is then drained away between feeds. Simple, reliable, and used across European high-tech greenhouses.

Why growers choose the Danish Hydro Tray:

• Pure ebb-and-flow principle — flood pots periodically, drain between feeds, let plants breathe
• Used in European greenhouse standard — the same principle powering high-tech commercial cultivation
• Fertilised and aerated water on a timer — precise nutrient delivery, optimal oxygen in the root zone
• Works with any potted growing medium — coco, clay pebbles, soil, mixed media
• Efficient water and nutrient use — reservoir recirculation minimises waste
• Simple, proven engineering — few moving parts, minimal failure modes

Who it's not for:

You'll need a separate reservoir and pump — the tray is just the top surface. Check dimensions match your tent size; a tray that's too big won't fit. Not compatible with hand-watered soil growing; this is a recirculating hydroponic approach.
