A crop production system (100) for a controlled plant growing environment is provided. A subassembly comprises a guide portion that includes passive guides (104, 504, 904, 1004) radiating outward from a central portion (102, 502, 520, 911). Each passive guide may be separated from two adjacent passive guides by respective angles. Each passive guide has a first end proximal to the central portion and a second end distal to the central portion. Each passive guide is configured to guide plant growth modules (210). The plant growth modules are movable between the first end and the second end of each passive guide. An active guide (406, 907, 1007) causes the plant growth modules to travel in a first direction along the passive guides as the active guide is moved.

The embodiments are apparatuses, systems and methods of water management and icicle prevention for solar carports, and are designed to catch drips between rows of, and water run-off from, the low side of inclined photovoltaic modules arranged to form the roof of the solar carport or canopy.

A system and a method for growing trellised plants are disclosed. The method may include growing the trellised plants downwards on rotatable tubes, letting gravity replace trellising and leaning and lowering of the plants may be replaced by wrapping their stems on the rotatable tubes, by rotating the tubes. The system may include: one or more cultivation systems; a plurality of angularly driving belts, for supporting and driving the one or more cultivation systems; and a rotatable shaft configured to rotate and carry the one or more cultivation systems hanging from the rotatable shaft by the driving belts. Each cultivation system may include a cultivation tube having a plurality of holes for planting the trellised plants; and an irrigation system for providing irrigation to the trellised plants.

An open-top gutter for cultivation of plants. In an example, the open-top gutter comprises at least one water space formed by a double edge and being closed at the top, or almost closed. The water space is open at the bottom of the gutter. In an example, the open-top gutter includes at least one separate water space formed by a partially double bottom and connected to the bottom of the gutter via a bottom gap. In an example, the open-top gutter includes a space limited by two side walls and a bottom wall and divided into trough-like compartments by at least one dividing wall. The dividing wall includes at least one water space formed by a double wall, open at the bottom of the gutter.

A method of applying a foil on an inclined roof structure having a ridge beam, a gutter, a plurality of parallel roof bars interconnecting the beam and the gutter and a ventilation opening frame which surrounds an opening that is located between the beam, the gutter and two neighboring bars, comprises: supplying a window frame that fits inside the ventilation opening frame, introducing the window frame within and holding the window frame at a fixed position with respect to the ventilation opening frame, laying a foil onto the roof structure such that it extends at least from the beam to the gutter and covers at least the neighboring roof bars, fixing the foil to the window frame and the ventilation opening frame along respective circumferential edges thereof, cutting the foil between the window frame and the ventilation opening frame, hence forming the window frame including the foil.

A new integrated unitary system for producing electricity for a greenhouse or other metal carpentry structure associates a photovoltaic system, an innovative apparatus reflecting solar radiation, and an innovative water system for cooling and washing photovoltaic panels, which are all combined with the greenhouse or the metal carpentry structure.

A shelving system for plant cultivation includes a frame, at least two vertically-spaced support racks, a plant support tray positioned atop each of said support racks, an optional forced-air ventilations system, and an optional lighting system. A pair of upright frame portions have support racks extending between the upright frame portions. The plant support trays each have a pot-supporting surface and a series of grooves or channels extending below the pot-supporting surface. Optionally, the plant support trays have integral water runoff troughs that receive runoff water from the grooves, channels, or openings. Optionally, a drive mechanism is coupled to the frame and is operable to cause the frame to translate along a floor surface.
