The system employs a two piece gully assembly to implement an NFT system. The system has a square-U shaped base with a flat lid that can be fastened to the base. One of the advantages of the assembly is in shipping where the bases and lids can be easily nested for transport. When compared to prior art gullies, the shipping volume of the present assembly is effectively minimized. In fact, ten gullies of the present assembly can be shipped in the same volume as a single prior art gully.
1. A gully assembly comprising:
a base member comprising a bottom member, two side members, and first and second rails formed on the side members;
a lid member having at least one opening formed therein, the lid member comprising first and second channels formed therein for receiving, and being retained by, the first and second rails; and
a plant holder inserted into the at least one opening,
wherein a top portion of the plant holder is above the lid member.
2. The gully assembly of claim 1 wherein the two side members are at an obtuse angle relative to the bottom member.
3. The gully assembly of claim 2 wherein the obtuse angle is approximately 105 degrees.
4. The gully assembly of claim 3 wherein the base member and the lid member are comprised of food grade plastic.
5. The gully assembly of claim 3 wherein the base member and the lid member are comprised of polyethylene.
6. The gully assembly of claim 3 wherein the base member and the lid member are comprised of polyethylene.
7. The gully assembly of claim 3 , wherein a notch aligned with a flow direction of nutrient film in the gully assembly is formed in the plant holder.
