The present disclosure relates to a new and distinct hybrid plant named Mr. Grass Weedly characterized by a hybrid between Cannabis sativa L. ssp. SativaCannabis sativa L. ssp. Indica (Lam.), characterized by a Cannabis sativa L. ssp. Sativa content ranging from 3 weight percent to 90 weight percent, Cannabis sativa L. ssp. Indica (Lam.) content ranging from 8 weight percent to 80 weight percent, a cannabidiol content ranging from 0.00005 weight percent to 15 weight percent, a tetrahydrocannabinol ranging from 5 weigh percent to 63 weigh percent, and a volatiles content ranging from between 30 weight percent to 90 weight percent. Variable-scale, modular, easily manufacturable, energy efficient, reliable, and computer-operated farming superstructure systems (FSS) may be used to produce Mr. Grass Weedly for human consumption with minimal water and environmental impact. A FSS system may comprise modules including liquid distribution and plant growing. A FSS may be configured to be constructed out of a plurality of containerized modules.

The invention relates to a coherent propagation growth substrate product (1) formed of man-made vitreous fibres (MMVF), the product (1) having two opposed top and bottom surfaces and at least one cavity (2) which is open at the top surface and which extends from the top surface towards the bottom surface, wherein a superabsorbent polymer (3) is provided in the cavity (2).

A hydroponics growing medium comprising mineral fibres and an organic binder, the growing medium has a Weathered Interlaminar Strength of at least 4 kilopascals and a phenol content of less than or equal to 0.01% by weight.

A grass sports ground is produced by mixing man-made vitreous fibres into soil having relatively high loam levels at a rate in the range 0.5 to 50 parts by weight per 100 parts soil (dry weight), preferably in the presence of moisture to separate the fibres and distribute them among soil particles, and then growing grass. The soil/fibre mixture has desirable moisture management properties as well as good mechanical characteristics providing extended use characteristics even in cold, wet or hot and dry conditions.

An apparatus for strip growing is presented. The apparatus includes a strip unit with an open channel throughout its length that is configured to hold multiple rectangular root balls with a desired spacing between root balls. The strip unit is defined by an outer bottom wall, an outer sidewall on each side of the outer bottom wall extending upwardly and terminating in an inwardly extending peripheral lip. The open channel is defined by a skirt extending downwardly from the lip and at an angle towards the outer sidewall and terminating at an inner vertical wall, and the inner vertical wall terminating at an inner bottom wall thereby forming the open channel with its bottom section larger than its top opening. A trough unit configured for automated harvesting, and to capture and guide irrigation water down the open channel is coupled to one end of the strip unit.

A man-made vitreous fiber (MMVF) plant growth substrate is provided together with an irrigation strategy for providing water to the substrate. The substrate comprises a slab having a volume of 3 to 20 liters on which a single block containing one or more plants is disposed. In the context of this substrate, it is found that an irrigation strategy can be used which comprises a first period during which the desired water content in the slab is reduced to a minimum level before increasing and a second period during which the desired water content is maintained at a substantially constant level, wherein the difference between the minimum level and the constant level expressed as a percentage of the water content required to saturate the plant growth substrate is less than or equal to 25%. This provides excellent control over the balance between vegetative and generative growth in the plant.

A method of growing plants in which the plants extend in a growing chamber can include emitting light from a light source onto a foliage of the plants, the light source being positioned within a light source conduit having an inlet and an outlet, and the emitted light being transmitted across a transparent wall of the light source conduit to the plants, circulating air in the light source conduit, the air circulating in the light source conduit absorbing heat from the light source, and transferring at least some of the heated air obtained from the outlet of the conduit to the growing chamber, thereby conditioning the temperature in the growing chamber. Other methods of handling the air medium are also presented.

A plant growth system and medium employs a manmade mineral fiber-based growth medium that includes from about 40% to about 99.5% man-made mineral fiber interspersed with from about 0.5% to about 60% by weight pieces of natural or synthetic open cell foam. The foam includes from about 5 to about 50 pores per square inch. Additives in the form of nutrients, fungi, and bacteria are included. Water is supplied to plants by flood and drain watering during plant growth in the medium. EC is maintained within a range of about 0.5 mS/cm to about 2.500 mS/cm and pH is maintained within a range of about 5.6 to about 5.8.
