Plant rafts with newly planted pouches float to and from work and production areas via 'end troughs'. As new rafts 'float' into trough, rafts with mature plants 'float' out of trough and return to the work/shipping area. "End gates" at either end of the production trough are hinged on the end distal from the work area; the gates are opened to direct and 'float' the plant rafts to and from the production trough and work area. During the rain season, precipitation drains from plant rafts into the underlying 'production trough'. During rains, excess precipitation overflows the trough 'endgates' into the end troughs to the collection reservoir.

This 32 cm thick styrofoam 'plant raft' can support 100 kg with a draw of 13 cm.
For production in the ‘Floating Plant Raft System’ determinant, green-shouldered, concentrated fruit set Tomatoes produce a wall-to-wall horizontal plant canopy for efficient supplementary lighting and eight, mature fruit for one-time harvest by day 120.
