Humidity is the amount of water vapor in the air. Here are some ways to control it in your marijuana grow room:

Below is a list of things to consider and equipment you will need to purchase to get started growing marijuana indoors.

Different lights produce different colors of light. Here’s a brief rundown of the most popular types of cannabis grow lights used for indoor growing.

Soil and other media for growing weed indoors

The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flower.

For the most part, weed prefers these temps at each growth stage for optimal health:

Adaptability

Unlike outdoor growing, you aren’t tied to the sun and the seasons. You will be providing the entire environment the plants need to grow, including the grow medium—soil, rockwool, etc.—and regulating the amount of water and nutrients they receive, as well as controlling temperature, humidity, and more for them.

For small spaces or tents, clip-on fans can be attached to structures like walls, corners, or support beams. For larger grow rooms, use medium-sized oscillating fans or big floor models.

The first step in creating a proper indoor growing environment is to decide on the medium and irrigation methods you’ll be using to supply your plants with the proper nutrients throughout their growth cycle. The medium is a shelter for your plants’ roots that retains moisture. The irrigation method is the way you deliver nutrients to the plants.

Soil

Controlling the amount of available carbon dioxide (CO2) in your garden is another aspect of growing marijuana at home . During photosynthesis, CO2 converts into sugar, which the plant uses as energy for growing its vegetation and, ultimately, its seeds or flowers. Adding CO2 to your indoor garden can drastically improve your yields. While the atmosphere naturally has an average CO2 concentration of around 400 parts per million (PPM), most indoor growers try to maintain a range of 800 to 2,000 PPM, depending on the plants’ growth stage. Levels above 2,000 PPM can damage plants, and anything above 3,000 PPM can be dangerous to humans.

Carbon dioxide supplementation

Ultimately, the costs of equipment and recurring utility bills are more expensive than in outdoor and greenhouse settings. However, specialized indoor cultivation equipment allows cultivators to achieve multiple harvests per year and a more reproducible product. If you’re detail-oriented and technologically inclined, indoor gardening is a fun and rewarding pastime, or could even be a full-time job.
