Atami WILMA XXL20 replacement drainage tray – 115 × 115cm

Atami WILMA XXL20 Tray (AW420TR) is an original replacement bearing and drainage tray for the Wilma XXL 20 hydroponic system. It supports the 20 pots above the nutrient tank and, through its shaped slope, returns the excess nutrient solution by gravity back into the tank. The size is 115 × 115 × 20 cm, corresponding to the square format of the Wilma XXL series. 

tray AW420TR is intended as a direct replacement component for the Atami Wilma XXL 20 system. The pots are placed in it, and the nutrient solution that drains after irrigation is collected and directed back to the tank, which allows it to be reused in the recirculation system. 

The configuration with 20 plant positions is suitable for denser placement of smaller pots on an area of ​​115 x 115 cm. The tray itself is a spare part - reservoir, pots, pump and irrigation system are not included. The official Wilma XXL 20 system uses a tank of 150 L and 20 pots of 6.5 L.

🔄 How

With the Wilma system, the pots are placed on the tray and the nutrient solution is supplied to each plant by drip irrigation. Excess water and nutrient solution pass through the pots and fall onto the tray, from where they return to the tank. Atami designed the Wilma as an automated drip system suitable for a variety of substrates – including coconut, peat mixes and hydroponic substrates.
