The friction clamp includes a cylindrical body of elongate form between ends and with a slot into which a tubular item is snapped. Lateral connectors such as a receiver with a cylindrical recess therein receive an end of a tubular member, such as a member similar to that which snaps into the slot. As an alternative to the receiver, a tab is provided extending from the clamp laterally. The tab includes a hole through which hardware is placed, and an item having a similar tab is placed adjacent to the tab extending from the clamp and the hardware tightened for fixation at a desired rotational orientation. As another alternative to the receiver, a small friction clamp connector is provided on an exterior of the friction clamp. A small rod (or other item) snaps into the small clamp. The small clamp and rod can be provided separate from the friction clamp.

An arrangement of photovoltaic panels is configured for installation in a greenhouse having support beams. The arrangement includes frames. Each frame includes at least one photovoltaic panel mounted on a rod. At least one motor is mechanically connected to rotate one or more rods, for bringing each photovoltaic panel to different fixed angular positions. Fittings are arranged at a perimeter of the arrangement. Each fitting is sized and shaped to attach to at least one of the support beams, such that the arrangement is supportable exclusively by the support beams. A system includes at least one such arrangement, a controller, and a plurality of sensors. The controller is programmed to select an optimal fixed angular position for each photovoltaic panel for promoting plant growth, based on environmental and plant conditions and the sensor outputs, and to instruct each motor to rotate each rod to the selected angular position.

The present disclosure provides a shade net made from a monofilament yarn and a shade house with the shade net made of the monofilament yarn. The proposed yarn has a low coefficient of thermal expansion a higher stiffness. The proposed shade net has a simpler construction and is lighter. A shade net made from the proposed monofilament yarn has demonstrated a capability of maintaining temperature and humidity within the shade house with a low co-efficient of variation of 10-15%, and maintaining a reduced temperature within the shade house by up to 3° C. compared to the ambient, with a result of an increased yield of crops by about 7-10% grown within the shade net.

A horticultural plant growing assembly includes a pair of casings, each with a bottom and a side wall. Each side wall includes an upper edge configured to engage one another to define a cavity between the casings. The plant growing assembly further includes a light system, and a plurality of frame members that are connectable together to form a frame, with the light system being attachable to the frame. The plant growing assembly is configurable into a packaged configuration and an assembled configuration. In the packaged configuration, the frame members and the light system are contained within the cavity, and in the assembled configuration the frame members are connected together to form the frame with the light system attached to the frame. One of the casings includes a shelf adapted to support a plant with the light system disposed above the shelf.
