Dutch Leach Tray with Fittings 

Also known as Rockwool grow trays, Dutch Leach Trays are a perfect fit for a 6" wide x 36" long Rockwool / Stonewool slab. 

Use these plant trays to hold Hugo Blocks or any loose growing media, such as coco peat, perllite or starter cubes. They'll also accommodate 1 or 2 gallon sized pots if you prefer.

Dutch Leach Trays have a channeled base to provide ideal drainage and air return. There are two small holes at one end of the tray which accommodate 2 elbows. Simply rotate the elbows so that they point down for draining and up for flooding.

Each Dutch Leach Tray includes:

1 Tray
2 Elbows
2 Plugs

Additional plugs and elbows available separately.

With Dutch Leach Trays, it's easy to create a do-it-yourself drip hydroponics system.
Exterior dimensions: 7-1/2" wide x 41" long.
