Provided is a plant cultivation device wherein the occurrence of tipburn is suppressed. This artificial light-type plant cultivation device 1 is provided with a cultivation chamber 4, the inside of which can be sealed. Within the cultivation chamber 4, the plant cultivation device is provided with: a cultivation room 10 for growing a plant; and an air circulation system 30 for generating an air flow from top to bottom in the cultivation room 10. Since the air circulation system 30 can blow air to a plant V from directly above, air is blown to new leaves growing in a central portion of the plant to promote transpiration. As a result, sufficient calcium can be supplied to the growing leaves and tipburn is less likely to occur.

A cover, and more particularly, a portable modular cover that may be assembled outdoors to keep insects and/or the elements from contacting food or other items spread out across small or large areas, and that may also be disassembled for ease of storage and transport, is disclosed. The portable modular cover provides solutions for protecting such food or other items through separate embodiments that are lightweight, durable, easy to assemble, and easy to travel with for virtually any occasion. When disassembled, the portable modular cover can easily fit within any suitable carrying case for ease of transport. Assembling the components together can be done on the fly at any outdoor event without requiring extraneous tools such as wrenches or screwdrivers. Opening and closing the portable modular cover can be done quickly and with ease to minimize exposure of food or other contents when accessing. Other optional accessories such as internal light fixtures can accommodate its use at evening outdoor events.

A method and system for managing bearing plants so that their belowground root-zones are clustered together to improve water-use effectiveness; and training their aboveground structures such that their aboveground structures have the wider spacing they require. It is applicable to plants (e.g., vine-like plants including wine grapes) whose trunks can be oriented at an angle other than vertical or which can be otherwise shaped so that their canopies are not centered above their root-zones but rather are horizontally offset from the root-zones.

A method for promoting the accumulation of cannabinoid substances is disclosed. The method comprises the step of adding an irradiation of green light, which has a peak wavelength at 505-526 nm, into the indoor growing environment of cannabis to improve the levels of tetrahydrocannabinol (THC) and cannabidiol (CBD), cannabinoid substances in cannabis. While maintaining the light intensity and other growth conditions, the yields and/or levels of THC and CBD, cannabinoid substances in cannabis, can be increased by up to 21.35%.

Methods to grow cannabis plants within an interior of an enclosure are described, the method comprises condensing water vapor from the interior of the enclosure to produce a source of liquid water and supplying the liquid water to the cannabis plants. The source of liquid water may be supplied to a common reservoir and then transferred to the cannabis plants. The common reservoir includes fish, a microorganism, or treated water. Water drained from the cannabis plants may be recycled back to the common reservoir. The water may be filtered or oxygenated and mixed with a pH adjustment solution, a macro-nutrient, a micro-nutrient, a carbohydrate, an enzyme, or a vitamin. Solar panels may be used to provide electricity for electrically powered lights that illuminate the cannabis plants. The cannabis plants may be grown within a growing medium, harvested, trimmed, ground, heated, and made into multifunctional compositions or foodstuffs.
