How to Build an Indoor Plant Growroom


Build an indoor plant grow-room that is dedicated only to growing plants or design one that is a showplace for the home while still acting as an active grow room. A grow-room that is dedicated only to growing plants, unless you are an accomplished gardener and are willing to stand the expense, is probably the first step to take. Design the grow-room to cultivate plants that blend in, as much as possible, to the conditions already existing in your home. Cultivating plants that require different growing conditions result in more equipment and expense. Gardening is an activity that is absorbing, relaxing and productive.

Step 1

Select a room that is unused, such as an extra bedroom or cellar that is out of the line-of- sight of visitors.

Step 2

Design the types of plants you will cultivate and determine the equipment and apparatus needed to support the growth of those particular plants.

Step 3

Trace out the size of the garden on the floor with masking tape, the placement of the tables on the floor, and the space needed for the plants to grow up and out. Take into account the height of the planters needed to accommodate the root systems of the plants you will grow.

Step 4

Make certain electrical outlets to power the florescent lights and a least one south-facing window for light and ventilation is available at the site you choose. A water supply, such as a faucet or a water-line that you can get access to is a definite bonus if you plan to put in an irrigation system.

Step 5

Lay a thick layer of plastic sheeting on the floor if it is carpeted or you don't want spilled water or dirt to damage it.

Step 6

Place sturdy tables in the area of the room where the garden will be located. The tables should have side-panels 3 inches high and be lined with one solid sheet of plastic form-fitted over the tables and stapled up the side-panels. Fill the plastic with a even layer of 1 inch of gravel. The plastic will catch the excess water from watering the plants. As the water evaporates it will provide needed humidity for the plants.

Step 7

Suspend fluorescent light fixtures from the ceiling, available from the home improvement store, at the heights recommended for the types of plants being grown. For best results, use one specialized florescent bulb that produces more light in the red range to every two cool-light bulbs that produce more light in the blue range.

Step 8

Control the temperature of the room as much as possible to correspond to the needs of the plants.

Step 9

Control the temperature of the room as much as possible to correspond to the needs of the plants.

Step 10

Use a timer to control the fluorescent lighting to correspond to the needs of the plants.

Tips and Warnings

  • Controlling both heat and cold is critical to the development of the plants. In winter, make certain heavy curtains or draft-proof plastic covers the windows. In summer, air-conditioning and fans should be used as necessary. Sturdy tables are a must. Gravel, planter pots filled with soil and plants that are watered regularly are very heavy.
