    Abstract: The present invention relates to a method of producing a coherent growth substrate product formed of man-made vitreous fibres (MMVF), comprising the steps of (i) providing MMVF; (ii) providing an uncured binder composition; (iii) providing an additive; (iv) forming a mixture of the MMVF, the uncured binder composition and the additive; (v) curing the uncured binder composition in the mixture to form the coherent growth substrate product; wherein the uncured binder composition comprises at least one hydrocolloid; and wherein the additive is a micro-organism, fungus, biologically-active additive or combination thereof.

    Abstract: A system (10,11) for controlling plant growth conditions in hydroponic growing systems, the system for controlling plant growth conditions comprising: at least one detector (7,1101) for measuring at least one property of a plant growth substrate; first (9,1103) and second (9,12, 1107) data processing means; data storage means (1120); and the or each detector (7,1101) being arranged to measure a property or properties of a plant growth substrate and to transmit a detector identifier and the measured property or properties over a communications link to the first data processing means; the first data processing means (9,1103) being arranged to: hold in a memory predefined irrigation data defining a relationship between: plural values for one or more of temperature, pH level, water content, nutrient content, oxygen content, and plant parameters of the substrate; and plural desired irrigation parameters; process measured properties received from each detector to obtain processed properties of the substrate; provide an output indicative of a desired irrigation input for the growth substrate, based upon the processed properties and the predefined irrigation data; and send processed data to the data storage means (1120), the data storage means arranged to store the sent data as logged data; the second data processing means (9, 12, 1107) being arranged to: receive data from the data storage means (1120); calculate predicted properties of the substrate based on the logged data; determine a difference between the processed properties of the substrate and the predicted properties of the substrate; receive an alert condition input for outputting an alert based on said difference; and output an alert when said difference meets the alert condition.

    Abstract: 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.
