A method of providing light to plants. The method comprises providing a plurality of plants within a room, grouping each plant of the plurality of plants into one of a plurality of groups of plants based at least in part on a desired total light integral (“TLI”) for each of the plurality of plants and providing the corresponding desired TLI to each plant of the plurality of plants by sequentially providing light to each of the plurality of groups of plants during a time period. For each group of plants, each plant has a substantially similar photoperiod and a sum of the photosynthetic photon flux densities (“PPFDs”) of all plants in the group of plants is substantially similar.

The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structure. The carbon dioxide is provided to greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby eliminating most greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission meat and 24/7 electricity at better than market rates.

Apparatus and methods for a hydroponics system with enhanced heat transfer are presented herein. By arranging the flow hydroponics system to have a series flow pattern via tubes and hydroponic pans, heat may be transferred from heat producing elements. The heat producing elements, including light emitting diodes (LEDs), may be thermally attached to the pans. The recycled heat can be transferred to the series circulating water supply for providing nutrient rich minerals at the roots of plants. Additionally, the heat can be transferred via the pans and without the need for costly fans or specialized heat sinks. In this way more space can be availed for the production of plants while recycling energy in the form of transferred heat.

A solar tracker system is a system and method to integrate the solar cells to a greenhouse. The solar tracker system comprises solar tracker modules that include solar cells, racks, gears, pinons, motors, and mounting brackets to efficiently and conveniently be installed to the roofs and walls of a new greenhouse and/or an existing greenhouse for retrofit application. Additionally, the solar tracker system uses various sensors to provide real-time conditions to the greenhouse. The method uses actual or system default values to adjust the angle and position of solar cells according to various environmental factors, such as DLI, weather, date, time, direction of sunlight, or type of plant.
