To provide ideal conditions of plant growth, protected from insects and pests etc.

A greenhouse is a house that is used for growing plants or to maintain the growing environment for plants. The glasshouse is a synonym of the greenhouse.
GREEN HOUSE
A greenhouse is a structure with transparent walls and roof, typically made of glass or plastic, used to grow plants that require controlled climatic conditions. Greenhouses provide a suitable environment for plants to thrive by maintaining warmth and humidity levels conducive for growth. They are commonly used for extending the growing season or cultivating plants that are not native to a particular region.
Seed
ScrOg, or Screen of Green, is a term used in the indoor growing of plants, specifically marijuana. A screen and netting is used to hold plants upward and towards the lights that are used for growing. The plants are trained to grow through the screen and netting.
Photosynthesis, same as outside the green house. So why do we use green houses? The green house is used to raise the temperature so that the plants start growing and are not killed by cold. It does this is two ways, by constricting air flow and blocking infrared light. The major part of this is that outside the green house, when the soil absorbs solar energy and turns it into heat, the air will transport that energy away which cools the soil and the plants growing in it. In the green house the warm air is trapped. To some (small) extent glass will block ultraviolet and infrared rays more than visible light. This stops harmful UV rays from hitting the plants, and it traps the infrared heat emissions from the plants inside the green house. Actually there is less useful sun light energy reaching the leaves within a green house than if the plants were outside it (try sunbathing under glass) but better control of temperature and humidity allows the plant to grow better anyway.

The answer is soil. Soil is brown and is used to grow plants in.
Soil is used for growing plants.
Plants are green because they contain a pigment called chlorophyll, which is used in the process of photosynthesis.
