The self watering bottle planter insert allows a regular bottle to be transformed into a hydroponic planter. The self watering bottle planter insert is insertable into a bottle and removes the need for a separate source of nutrients. The planter uses composite media with an enriched substrate layered beneath a more standard hydroponic growth media to add nutrients to the water for the life cycle of the plant.

A mineral wool batt for use as a plant growth medium, particularly in applications for growing vegetation (including plants) in which water retention and/or the avoidance of water run-off is of interest. The mineral wool batt has an absorbent layer which comprises needled mineral wool fibres; superabsorbent particles in the absorbent layer may be sandwiched between a denser upper and/or lower barrier layer(s) which assist in preventing their escape.

A hydroponic plant display that allows consumers to select and harvest fresh produce while shopping at their local market. The display system maintains the health and vitality of the produce until it is selected by the end consumer for harvesting. As such, the display system includes (i) a plant display, (ii) plant growth media that provides a suitable support system for each plant's root structure, and (iii) a moisture and nutrient transport system.

Methods to produce a spray dried cannabidiol, tetrahydrocannabinolic acid, or active tetrahydrocannabinol powder are described and include spray drying a liquid mixture followed by a two-step separation process including cyclones, filters, or an electrostatic precipitator, the liquid mixture includes treated water, and alcohol or an oil, and the powder has a particle size ranging from between 5 nanometers to 750 microns. The liquid mixture may be spray dried into a powder using a rotary atomizer, a spray nozzle, or a plurality of spray nozzles within a counter-current spray dryer or a co-current spray dryer and then sifted.

Hydroponic growing systems are gaining in popularity because of the relative ease of use and these systems eliminate the traditional problems with growing plants in earth: insects and fungus, among other issues. Hydroponic growing systems do not depend on soil and therefore the issue of insects and bugs and/or other harmful elements to plants are largely avoided. The device in this case circulates water through a closed system on a timed basis; the primary issue for this system is accommodating the right growing conditions for the plant. This issue is addressed by using substrate to promote healthy plant growth.

Methods to produce a spray-dried active tetrahydrocannabinol powder and/or cannabidiol powder are described. The methods include introducing a heated gas and a liquid mixture of water and active tetrahydrocannabinol and/or cannabidiol into a spray dryer and then separating powder from the spray-dryer in a two-step separation process. Counter-current spray dryers and co-current spray dryers are described followed by separation of the powders with a cyclone, filter, electrostatic precipitator, or sifter.
