Large trays on which you can grow in pots or on coconut or rock wool substrate boards.

These substrate trays are very practical and clean as the drainage is collected in one place. They are the most commonly used in greenhouses and come with accessories sold separately, one of which is the grow table filter that prevents substrate particles or leaves from entering the feed tank.

Recommendations for using the grow tray without a hole

To prevent the filters from becoming blocked or algae from growing in these trays without a hole, it is advisable to use these trays with the special irrigation blanket for this type of application.

With this grey grow tray with a hole you can collect excess water after watering your crops by channelling it all into the hole in these substrate trays.

How to use the grow tray with a hole

These trays, with a 3.5 cm hole, will collect all the excess irrigation water from your crops and carry it to the drainage area. For the drainage system to work, we must place the grey growing table with a hole at an angle so that all the water goes towards the drain by gravity.
