DIY Grow Chamber


If you love to garden but don't have the necessary climate or outdoor space required to grow your favorite fruits, vegetables or herbs, an indoor grow chamber could be the answer to your problem. With a grow light system, some reflective paint, a fan and a little elbow grease, you can turn an ordinary closet or cabinet into a contained environment where you can successfully grow all your favorite plants.

Step 1

Choose a suitable space to set up your grow chamber; a small to medium-size closet or cabinets are ideal for your first indoor growing set-up.

Step 2

Clean the inside of your growing chamber thoroughly before introducing any plants. Wipe down the walls, ceiling, door and any shelving in your grow chamber with a sponge that has been dampened with an all-purpose bleach cleaner. Allow the inside of your grow chamber to air dry.

Step 3

Paint the walls, ceiling, door and shelving in your grow chamber with a high-gloss reflective white paint to make the chamber highly reflective. Affix sheets of silver Mylar to the wall, ceiling, door and shelving in your grow chamber to serve the same reflective purpose.

Step 4

Cover the floor in your grow chamber with several sheets of thick plastic to prevent any damage due to water, fertilizer or soil spills.

Step 5

Choose a grow light system for your grow chamber that comes with both a ballast and reflector. Attach the grow light system to the ceiling in your grow chamber. Set up your grow light system in a way that makes it possible for you to raise and lower the grow light as your plants grow.

Step 6

Install a fan in the ceiling of your grow chamber, next to the grow light system. Turn the fan on and point it toward the grow light system. Run the fan as often as necessary to keep the air in your grow chamber circulating and the temperature below 80 degrees Fahrenheit.

Step 7

Select the method that you want to use to grow your plants. Grow your plants in traditional planting containers filled with well-draining growing medium or choose a more elaborate hydroponic growing system. Select simple hydroponics such as an ebb-and-flow system or a drip system, if this is your first attempt at growing plants indoors. Choose a more complicated nutrient film technique, aeroponic or wick hydroponic system if you have previous experience growing with hydroponics.

Tips and Warnings

  • Grow only legal fruits, vegetables, herbs and flowers in your grow chamber. If you are using your grow chamber to grow medical marijuana, make sure to post all the necessary legal paperwork just outside the entrance of your grow chamber.
