Claims
- 1. A modular plant device which comprises at least two longitudinal troughs arranged in parallel relationship, the walls of each of said troughs including a plurality of slits in opposed relationship, a support member comprising a film-like sheet material draped over the walls of the troughs and forming a floor therebetween, a plurality of partition members received within the opposed slits of the parallel troughs and transverse to the troughs and extending beyond the upper edges of the walls of the troughs, end plates secured to the ends of the partition members to define with the members and the sheet material an enclosed channel, the sheet material secured between the partition members and the slits receiving said members.
- 2. The device of claim 1 wherein the troughs are abutted one end to another end in longitudinal relationship to extend the lengths of said troughs.
- 3. The device of claim 2 wherein the troughs are secured in frictional engagement.
- 4. The device of claim 3 wherein the one end of a first trough is telescopically received in the other end of the next trough.
- 5. The device of claim 1 which includes a flange comprising two arms adapted to be received in the opposed slots of a trough and a strengthening rib, the rib adapted to abut the surface of an opposed partitioning member.
- 6. The device of claim 1 wherein the end plates are fluid permeable and each having a planar surface and two arms formed transversely to said surface said arms engaging slits of the trough and the planar surface forming the end of and closing a channel.
- 7. The device of claim 1 which includes a plurality of partition members defining growing channels and service channels in alternating relationship, the partition members between said channels being fluid permeable.
