Each of the laminate materials comprises a first layer 21 of reinforcing material and a second layer 23 of fluid absorbent, fluid conductive material. A third layer 25 of waterproof material may be interposed between the first and second layers. The second sheet is secured to the first sheet so as to form at least one pouch 18. The first and second sheets may be secured together so that they are in fluid communication 26. Each pouch may be filled with growing media. Also disclosed is a compostable or biodegradable laminate material comprising a first layer of reinforcing material, a second layer of fluid absorbent, fluid conductive material, and a third layer of waterproof material.
