The invention relates to a ventilation system and method for promoting growth of a plant. The system comprises an air inlet provided at a first height from a defined floor level, an air outlet, fluidly connected to the inlet, an air moving device for moving air from the inlet to the outlet, and a plant growing surface, provided at a second height, being higher than the first height, for accommodating growing plants, wherein the air outlet is provided at a third height, being higher than the second height. The inventive concept is based on the inventors' realization that improved growing conditions can be provided by transporting CO.sub.2 from the bottom of a lower level in a greenhouse to a higher level.

This invention relates to methods and materials for providing a benefit to a plant by associating the plant with a complex endophyte comprising a host fungus further comprising a component bacterium, including benefits to a plant derived from a seed or other plant element treated with a complex endophyte. For example, this invention provides purified complex endophytes, purified complex endophyte components such as bacteria or fungi, synthetic combinations comprising said complex endophytes and/or components, and methods of making and using the same.

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%.

Described herein is the evaluation of the antifungal properties of bacterial strain KGS-3 against Fusarium Head Blight (FHB)) white mold, blackleg and a number of potato fungal diseases and the plant growth effect attained. KGS-3 is a novel strain of Paenibacillus polymyxa that can suppress bacterial and fungal plant diseases. KGS-3 is predicted to produce antifungal metabolites polymyxin, fusaricidin, and paenilarvin and has been demonstrated to produce cylindrol B. KGS-3 is a plant growth promoting bacteria demonstrated to increase protein content of plants and/or plant products.

The present invention is new art with a new function and is comprised of box or container that is composed of grass, dirt, herbs and any and all toys to decorate the backyard. The intent is for kids to create their own real-life backyard by growing grass, cutting the grass, watering the grass, planting herbs and putting toys and items in the backyard to decorate as they see fit. This toy will help educate kids on becoming a gardener while teaching them responsibility.

A spectrum for promoting growth of cannabis plants. The spectrum comprises adding an irradiation of red light with peak wavelength at 655-690 nm into an indoor growing environment of cannabis to improve the levels of THC and CBD, the cannabinoid substances in cannabis. A ratio of photon number of the red light to the photon number of the entire light source is in a range from 40% to 70%. While maintaining the light intensity and other growth conditions, the yields and levels of THC and CBD, the cannabinoid substances in cannabis, can be increased by up to 32.48%.
