What Is a Stealth Grow Box?
A stealth grow box is an enclosed container designed to provide a controlled environment for growing plants indoors. The main purpose of a stealth grow box is to keep your plants hidden from view, making it an ideal solution for individuals who live in areas where growing cannabis is not legal or socially accepted. These boxes are often designed to blend in with their surroundings, looking like any other piece of furniture or household item, such as a cabinet or refrigerator.
I think that,, a stealth grow box typically incorporates features such as ventilation, lighting, and a hydroponic system to ensure that plants receive the proper nutrients, moisture, and light needed for optimal growth.
The conditions are easy to regulate and maintain automatically, allowing you to achieve high yields without much effort. So, if you’re looking for a discreet way to grow your own produce at home, then a stealth grow box is definitely worth considering!

How To Build A DIY Stealth Grow Box– Complete Guide?
Building a DIY stealth grow box is an easy and affordable way to start growing your own plants indoors. Here are the steps to get you started:
Step1: Gather Materials
Gathering the right materials is essential when building a DIY stealth grow box. You will need seven pieces of industrial particleboard, three-inch wood screws, eight building studs at 2x4x8 and 20 feet of 1-inch steel chain.
In my opinion,, you’ll need a staple gun, wire cutters, a circular saw, some duct tape and a cordless drill to get the job done properly. Buy high quality materials that are designed for use in humid environments, as this will help ensure the longevity of your grow box and its contents.
Step 2: Cabinet Frame and Assembly
I have tested and seen that you need to start by framing out the cabinet, using the 2x4s and 3-inch wood screws. The frame should measure about 44 inches long, 24 inches deep, and 36 inches tall. Cut to fit and position the building studs for the frame, then measure and cut the particle board to fit the frame.
Once you have all your pieces cut to size, it’s time to start assembling. Place the back, sides, floor, and top on the frame of the cabinet, securing each piece with wood screws or a staple gun.
Make sure your measurements are accurate so that everything fits together nicely! Once you have built your frame and secured all pieces in place with either screws or staples, you’re ready to move onto installing lighting and ventilation components.
Step 3: Install the Fan
From my experience, begin by cutting a 6×6” hole in the upper right-hand corner of the cabinet, then cut a one-inch slot about four inches from the ground on the left side of the cabinet for cross ventilation. Next, place your fan inside the cabinet and secure it with screws. Then, connect it to an extension cord and make sure that it is properly wired.
Finally, plug in the fan to complete installation and ensure proper airflow within your grow box. Now that you have successfully installed your fan, you are ready to move onto installing lighting components!
Step 4: Install Lighting and Irrigation
Begin by selecting the appropriate lights for your grow box – either LED or CFL will do. Install the light, adding dual bulb adapters if you want to be able to install two bulbs per socket. Secure them in place with a frame made of one-inch stainless steel chains and bungee cords so that they are easily adjustable.
Additionally, use an extension cord to connect the interior of the box to an exterior outlet. Finally, install Mylar blankets inside the box to ensure that heat is trapped within it and can’t escape.
Step 5: Install the doors
From my experience, you’ll need two hinges of 1.5 inches each and a self-closing flush cabinet hinge. Place the hinges on the inside of your box, making sure that they meet in the center. Once you have them in place, use screws to secure the hinges to the box frame. If desired, attach a lock to one of the doors for added privacy.
To help ensure that light and air are kept out of your box, use weatherstripping around each door frame. Finally, add handles or knobs to make it easier to open and close your doors.
Step 6: Lay the Tarpaulin
When building a stealth grow box, it is important to lay a tarp at the bottom and floor of the walls. This helps to prevent rotting due to contact with water. To do this, simply cut the tarp to fit your cabinet measurements and staple it to the top and bottom.
Make sure that you are using a large tarp, as it will provide more protection from water damage. Additionally, you may want to consider using weatherstripping around each door frame in order to keep light and air out of your box.
Step 7: Set the Timer and Thermometers
Once you have constructed your stealth grow box, it is time to install a timer and thermometer. This will ensure that your plants remain at the optimal temperature during their growing cycle.
From my experience, when installing the timer, make sure to follow the instructions carefully and remember to set it for the right amount of time in order to achieve the best results. The thermometer should be placed inside the box so that it is not exposed to direct sunlight or wind.
Once you have secured the thermometer, you can use a hygrometer or digital humidity gauge to measure the humidity level in your box. By following these simple steps, you will be able to monitor the environment of your stealth grow box with ease!

BONUS: Tips for Growing Plants in a Hydroponic Stealth Grow Box
Here are some tips to help you grow plants successfully in a hydroponic stealth grow box:
- Start with healthy plants. Choose healthy plants with strong stems and bright green leaves to ensure the best chance of success. Avoid plants that show signs of stress or disease.
- Keep the grow box clean. Regularly clean the grow box, including the hydroponic system and any growing surfaces, to prevent the buildup of algae, mold, or bacteria.
- Monitor pH levels. Keep a close eye on the pH levels of the nutrient solution, as this can affect the absorption of nutrients by your plants. Aim for a pH level between 5.5 and 6.5 for most plants.
- Use the right nutrients. Use high-quality nutrients designed specifically for hydroponic growing to ensure that your plants receive the proper balance of essential nutrients.
- Maintain proper temperature and humidity. Hydroponic plants grow best in a temperature range of 68-78 °F and a relative humidity of 50-70%. Use a thermometer and a hygrometer to monitor these conditions and make adjustments as needed.
- Ensure adequate lighting. Use high-quality LED grow lights that provide the proper spectrum of light for your plants. Aim for at least 18 hours of light per day during the vegetative stage and 12 hours per day during the flowering stage.
- Train and prune your plants. Prune your plants regularly to promote healthy growth and increase yields. Use techniques such as topping, lollipopping, and training to shape your plants and maximize their growth potential.
