Preparation

The preparation step in building a grow room requires attention to detail. You will start by measuring the area you want to set up the grow room. 

That is because you must determine the space required to set your plants, and all the resources. 

Collect all needed materials, including the seals, drywall, and fans. Insulation will also require materials that can block light out from your garden. Proper preparation ensures you can create the perfect controlled environment for your plants. 

Building a sealed grow room setup requires careful planning and attention to detail. Start by measuring the area where you plan to build the grow room. You’ll need to know the exact size of the cultivation space to determine what materials and equipment you’ll need. 

Gather the necessary materials for the project, including insulation, drywall, plastic sheeting, and a strong airtight sealant. 

When it comes to insulation, use a material that will block out light and keep the room temperature balance consistent. Once you have all of the materials in place, begin constructing the walls of the grow room. 

Environmental factors are also crucial in the preparation stage. These include air exchange, light levels, temperature, and humidity. 

Ensure you also consider the plant types you will set in the grow room. The best temperature for indoor plants averages between 20 to 25 degrees Celsius. Plants that are exposed to excessive heat won’t grow as required. 

Sealing and Insulation

Sealing and insulation is the other vital factor to consider in setting up your grow room. We recommend you start this process by sealing the grow room using the right resources. 

This includes high-quality plastic sheeting, which will help produce a barrier that seals out vapor. 

Ensure you apply to sections of the grow room like walls and ceiling. The door, and window openings will also require sealing to stop air leak issues. 

Ensure you place the plastic on the edges of the walls, the doors, and the Windsor frames. We recommend you settle for professionally mounted doors. You will also get a silicone sealant to cover any sections that are difficult to access. Silicone sealant is also easy to use on resources like pipes or other openings in your walls. 

Once you set the sealant and plastic sheeting. Set up weather stripping on the doors. Weather stripping is usually a foam strip applied to your doors and windows. The other factors to consider when sealing and insulating a grow room are:

1. Check for light and air leaks. Ensure all doors, window frames, roofs, and water chilled lights are free from any apertures. Seal the light and air leaks using products like caulk and weatherproofing when possible. 
2. Insulate ceilings and walls. You must set up insulation on the walls and ceiling to help maintain humidity and temperature. Ensure you also use the insulation thats suited for the size and nature of your grow room
3. Set up vents. Vents are essential for the circulation of fresh air. It directs air from the outdoors and directs exhaust air to escape. A fan helps with air circulation levels in vents. 
4. Check the grow lights. Remember to check your grow lights, especially the bulbs, and the light intensity. Plus, the lights will also require sealing around the edges to stop issues like light and air leaks.
5. Set up a dehumidifier. A dehumidifier helps maintain the quality of air in your grow room. Ensure it’s well sealed on the edges as well. 
6. Seal the doors. The doors might be entry points to your garden, but they also require sealing. Many indoor cultivators often have measures to ensure these challenges don’t occur.

Climate Control

Owning a successful grow requires the right climate control measures. Part of this process involves maintaining temperature, humidity, and airflow. Here are a few details of the species involved in all procedures and their relevance to climate control:

• Temperature. The best temperature for a grow averages between 65 and 85 degrees Fahrenheit. Using excessively low temperatures can stunt plant development or lead to issues like wilting. We recommend you use a mini split ac system for room cooling purposes.
• Humidity. The ideal humidity for sealed grow rooms averages between 39 to 59%. Excessive humidity can lead to disease, mildew, and mold issues. We recommend a dehumidifier to help you regulate this process. 
• Airflow. Airflow is crucial for the quality and environment of grow house. Resources like fans help to produce a gentle breeze that movies air in your garden. It also helps prevent the accumulation of pests and diseases. Maintaining the correct airflow will have positive results for your garden. 
• Lighting. Lighting is crucial for your plant’s ability to photosynthesize and produce energy. Different lights are suitable for growroom, and each helps with climate control applications. 
• Ventilation. Ventilation is also essential for ensuring plants receive optimal carbon dioxide and oxygen for survival. A resource like intake fans can be helpful for the regulation and supply of air to your grow room. Plus, you also need to clean these fans regularly for a clean garden.
• Filtration. It’s also essential that you remove the air in your grow room. Ensure it is free from pollen, dust, and other airborne particles that can cause plant harm. Consider getting a resource like an air filter for air purification, and to improve the living conditions of your plants. 

Lighting 

You should consider various factors when setting up the lighting in your grow room. You must consider the lighting needs and the amount your plants will require. 

Factors like the grow room size will be necessary for this process. Usually, a sealed grow room works best with LED or High-Intensity Discharge (HID) lights. 

These lights are highly energy efficient and will produce less heat when compared to the HID alternatives. Thus, these lights are perfect for when you have a sealed grow room. 

You will also usually find various light sizes, wattages, and brands. So customizing the lights to suit your grow house will require some time and research on your end. 

The best placement of grow lights should be in a grid pattern. Why is that? It’s because this provides optimal coverage using an evenly spaced grid pattern. Other factors you should consider regarding lighting include

• Lighting size. Consider the number of plants you want to grow when picking the light size. Other factors like the size of grow space, and your light intensity is also crucial. Usually, 25 watts of light per square foot is best for plant development. A good example is when you are growing plants in a 4 x 4 setup – we recommend you set up a 400-watt light for this space.
• Spectrum. Optimal cannabis growth also requires light that produces a full light spectrum. Therefore, ensure you use a unique combination of blue, green, and red lights. The ratio of these colors often varies based on your plant’s growth stage. Plants thrive when you maintain the right light spectrum levels.
