Interlocking raft segment for deepwater culture hydroponics
First Claim
1. A raft segment for deepwater hydroponic culture, comprising:
- a. a sheet of buoyant material having a plurality of first plant holes therethrough, at least one of said plant holes having a wider top dimension than a bottom dimension, each of said plant holes sized to retain a plant body with said plant'"'"'s roots suspended in a tank or pond of water;
b. said sheet having a recessed area extending upwardly from the bottom of said sheet; and
c. one or more continuously tapered thermal chimneys through said sheet of buoyant material at said recessed area, at least one of said thermal chimneys having a wider bottom dimension than a top dimension.

Abstract
Embodiments of a hydroponic growing system include raft segments that can be reversibly attached together to form a raft. Rafts can have one or more plant holes to support a plant body, and one or more thermal chimneys to provide for gas transport from underneath the raft to the upper surface, to control temperature and humidity of the plant. Additional embodiments include wireless sensors that may or may not be part of a raft, and a growing environment control system that can receive data from one or more sensors of environmental conditions of a plant and in other embodiments, can detect discrepancies between the actual environmental conditions and desired conditions. In still further embodiments, a growing environment control system can automatically adjust an actuator to return an environmental condition to a desired state.

13. A system for hydroponics, comprising:
-
a plurality of opaque raft segments, each segment comprising a sheet of buoyant material having a recessed area extending upwardly from the bottom of a sheet, a plurality of plant holes through said sheet, said raft segments reversibly attached together to form a raft to completely cover the surface of a pond, at least one of said segments having a continuously tapered thermal chimney through said sheet at said recessed area, said thermal chimney having a wider bottom dimension than a top dimension; a source of aeration bubbles; one or more environmental sensors, each of said sensors to measure an environmental variable of the environment of said raft; and a platform control system to; a) store or transmit to a remote location information captured by said one or more environmental sensors; and b) compare said information with previously stored benchmark data; and c) identify discrepancies between said information and said benchmark data; and d) transmit one or more signals to a solenoid, and actuator, or other controlling device to adjust the environment to bring it into benchmark tolerances.
