Make a Rubbermaid Grow Box for Cannabis Growing

Growing cannabis at home can be a rewarding and cost-effective way to cultivate your favorite plant. A Rubbermaid grow box is an excellent solution for those looking to grow cannabis discreetly, efficiently, and affordably. In this article, we'll walk you through the process of creating your own Rubbermaid grow box for cannabis growing.

What is a Rubbermaid Grow Box?​

A Rubbermaid grow box is a homemade, self-contained growing environment made from a Rubbermaid storage container. It is designed to provide an optimal environment for cannabis plants to grow, while remaining discreet and affordable.

Materials and Tools Needed​

To create your Rubbermaid grow box, you'll need:

• A Rubbermaid storage container (18-gallon or larger)
• Reflective material (Mylar, aluminum foil, or white paint)
• Duct tape
• A small oscillating fan
• A grow light (CFL or LED)
• A timer
• A power strip
• A thermometer/hygrometer
• A power drill with a hole saw bit
• Wire mesh or screen material
• Zip ties
• Optional: Carbon filter and exhaust fan

Step 1: Prepare the Rubbermaid Container​

Start by cleaning your Rubbermaid container thoroughly. Remove any stickers or labels, and ensure the inside surface is free of any dirt or debris.

Step 2: Line the Interior with Reflective Material​

Next, cut your reflective material to fit the interior of the container. Mylar is the most effective, but aluminum foil or white paint can also be used. Use duct tape to secure the reflective material to the inside walls of the container, ensuring there are no gaps or overlaps.

Step 3: Install Ventilation​

Using a power drill with a hole saw bit, cut two holes in the top of the container – one for the intake vent and one for the exhaust vent. The intake hole should be smaller than the exhaust hole to create a negative pressure environment, which helps with odor control. Cover both holes with wire mesh or screen material to prevent pests from entering the grow box. Secure the mesh with duct tape or zip ties.

Step 4: Set Up the Grow Light​

Choose a grow light that best suits your needs. Compact fluorescent lights (CFLs) and LEDs are popular choices due to their low heat output and energy efficiency. Mount the grow light to the lid of the container using duct tape or zip ties, ensuring it is securely fastened. Plug the light into a timer, and set it to a 18/6 light schedule for vegetative growth or a 12/12 schedule for flowering.

Step 5: Install the Oscillating Fan​

Place a small oscillating fan inside the container to promote air circulation and prevent hotspots. Ensure the fan is not blowing air directly on the plants, as this can cause stress and damage. Plug the fan into the power strip.

Step 6: Add a Thermometer/Hygrometer​

Monitoring the temperature and humidity within your grow box is crucial for maintaining an optimal cannabis growing environment. Place a thermometer/hygrometer inside the container, ensuring it is easily visible.

Step 7: Optional - Install a Carbon Filter and Exhaust Fan​

If odor control is a concern, consider installing a carbon filter and exhaust fan. Attach the fan to the exhaust hole, and connect the carbon filter to the fan using ducting. This will help reduce the smell of cannabis as it grows.

Step 8: Plant Your Cannabis​

Once your Rubbermaid grow box is complete, plant your cannabis seeds or seedlings in suitable containers with appropriate growing medium. Place them within the grow box, and adjust the grow light as needed to maintain the correct distance from the plants.

Step 9: Monitor and Adjust​

Regularly monitor the temperature, humidity, and plant growth within your Rubbermaid grow box. Adjust the light schedule, ventilation, and other factors as needed to ensure your cannabis plants thrive.

By following these steps, you can create a discreet and affordable Rubbermaid grow box for cannabis cultivation. With proper care and attention, your cannabis plants will flourish in this controlled environment, providing you with a satisfying and cost-effective DIY growing experience.
