How to Cover a Grow Room Window


Growing plants indoors in a soil-less growing medium, a method known as hydroponic gardening, is becoming more popular. Eliminating the chance of contracting soil-born disease and the ability to grow plants that wouldn't normally be hardy in your area are two of the biggest draws to growing plants indoors hydroponically. The first step to hydroponic gardening is to set up a suitable grow room. Having absolute control of the lighting conditions for your plant is essential; cover windows in your growing room to make this possible.

Step 1

Measure the size of the grow room window you want to cover, using a measuring tape. Make a note of the window's dimensions and add 3 inches to each side.

Step 2

Cut a piece of black vinyl sheeting to your amended window measurement (the window dimensions plus 3 inches). Use a pair of sharp scissors to cut through the vinyl sheeting without leaving jagged edges.

Step 3

Center the piece of vinyl sheeting over your grow room window. You may want to have an assistant help you hold up the vinyl sheeting, if needed. An assistant can also help you gauge whether the vinyl sheeting is properly centered over the window.

Step 4

Cut additional pieces of vinyl sheeting if the light is able to penetrate a single sheet. Layer additional pieces of vinyl sheeting, if necessary, until no outside light penetrates your growing room.

Step 5

Tape the edges of the piece of vinyl sheeting over your grow room window with duct tape. Secure the vinyl sheeting over your window by using a hammer stapler to add staples every 12 inches around the perimeter of the window. For best results, staple through the duct tape.

Tips and Warnings

  • When covering a grow room window, provide an alternate source for ventilation. Without proper ventilation, grow lights can cause your grow room to heat up to temperatures that may damage your plants.
