How to Set Up Your Cannabis Grow Room

Indoor cannabis production is a perfect opportunity to kick-start your cannabis production empire, whether you are starting with stealth grow box, a single grow tent, or a commercial facility. Allow us to walk you through the steps to get you to operate your very own marijuana production. By growing cannabis plants indoors, you have the control to influence all the requirements that the plant needs such as light, water, nutrients, temperature, ventilation, and humidity. You’re able to optimize your production for maximum yield.

Advantages of a Grow Room

Growing cannabis outdoors is a lot easier than indoors. While setting up a grow room is not cheap, it is a good way to maximize your yield and your profits.  The main advantage of having a grow room for your cannabis plants is that they are protected from natural challenges as well as roadblocks. You can test things out in a single grow box. This is a good way to get started since there are many factors required for growing cannabis even on a small scale. You gain full control of the growth and development of your cannabis plants indoors by manipulating the requirements to meet your expectations and desired results. Grow rooms are perfect if you are living in a limited space like an apartment or condo. This is also a stealth way of growing marijuana.

What Cannabis Plants Need in a Grow Room

The general idea of a grow room is to create an ideal environment where your marijuana plants will live and prosper. The better they undergo photosynthesis, the better is the output in terms of quantity and quality.

  • Light (reflector, wall color, and lamps)

Marijuana plants require proper lighting for photosynthesis. It is important to find a room that’s completely lightproof, so you can carefully choose the light and darkness hours. During the vegetative stage, your cannabis plants require 18 hours of light and 6 hours of darkness. During the flowering stage, your marijuana plants need 12 light hours and 12 dark hours. Using reflective walls can make the most out of your grow room lighting and white walls work best. Also, using a time switch can make things a lot easier for you and create the best indoor lighting experience for your marijuana plants.

  • Ventilation

Find a grow tent or room that is airtight because the stench of cannabis could easily reach your neighbors and bother your surroundings. That’s why fresh air and air circulation are very important. Outgoing air should pass through a carbon filter. On the other hand, an air extractor removes the heat for the lamps, thus keeping the temperature stable and helps in removing the strong odor of the cannabis plants. For consistent air circulation, using a fan helps, so the carbon dioxide and temperature will spread evenly in the grow room.

  • Water and Humidity

The water that is running from the pots to the floor of the grow room is inevitable. That is why the floor should be waterproof. Also, the right amount of moisture is needed in the air to push the growth of plants. No too much humidity, otherwise, it will cause mold and fungus.

  • Temperature

A fan and airflow system will help prevent overheating of your marijuana plants. Temperature is crucial for your cannabis plants, most especially for the photosynthesis. You need to align the temperature to the light and darkness hours because you want a higher temperature during the lighting time as compared to the dark hours. The best temperature is 77 degrees Fahrenheit. Not below 64 and not higher than 86 degrees Fahrenheit. The lamps will provide enough source of heat during the day. You may also consider extra heating at night.

  • Nutrients

Cannabis plants need nutrients so it is essential to measure them on a regular basis. They need nitrogen, potassium, and phosphorus. You can use nutrients blends but the number of nutrients they need will depend on their growing cycle, so be careful not to go overboard because too much will burn your plants. Nitrogen toxicity may result.

  • Security

The windows of your grow room should be sealed and use a carbon filter to fight the cannabis scent. Use extra locks and CCTV cameras most especially when you’re growing in a warehouse. Do not put your crop at risk.

Marijuana Grow Room Setup Checklist

Here is a quick checklist to help you set up your cannabis grow room.

  1. Make a blueprint. Regardless if you choose a basement at home or a warehouse, it’s best to start creating a blueprint for your growing room. Determine how many square meters needed and how many marijuana plants you can put.
  2. Prepare the space. You need to remove all unnecessary things such as carpets, furniture pieces, and decoration. Make sure that there are accessible electricity and plumbing proximity to where you are planning to place your lights and pots.
  3. Set up the water and light systems. Hanging light fixtures, running the necessary wiring, plugging them in and testing each one are all equally important. Be sure to install and check the water system.
  4. Prepare the pots. You need to lay out the pots, soil or growing medium, and the seeds or clones in the right quantity and arrangement based on your blueprint. Everything should line up as expected and you have everything you need.
  5. Start planting marijuana. A grow tent is a quick and easy way to introduce growing cannabis in hydroponics.


Setting up a grow room requires the right supplies and tools. Growing indoors is simulating the ideal environment of cannabis plants outdoors, but you have full control of the lighting, temperature, ventilation, humidity, water, nutrients, and other factors affecting their growth and survival. Careful planning is crucial so you need to have a blueprint or basis. Of course, setting up a grow room does not come cheap, so you need to also research the costs of supplies you need for the best results.
