Building indoor greenhouse is as easy as finding a suitable area in the house where temperature can be controlled for the plants to grow. This can be a closet, the basement, an attic or even a spare room.

Advantage Of Building Indoor Greenhouse

Compared to outdoor greenhouse, building indoor greenhouse is relatively easier. The simplest is to cover the walls and floor with plastic to protect them from water. Plastics can even be held to the walls by thumb tacks.


The more sophisticated approach of building indoor greenhouse is to build it with frames and plywood. This would require strips to fasten the leg braces and more fluorescent lights on chain wiring. Building indoor greenhouse with such materials allow the greenhouse to be moved around indoor, such as from rooms to basement.

Indoor Greenhouse For All Seasons

Building indoor greenhouse would allow plants and seedlings to grow all year long. Fruit and vegetable crops would also propagate early before the outdoor temperatures would allow. Sensitive crops do well growing in an indoor greenhouse, and they can then be transplanted outdoors once the summer growing season begins.


Building indoor greenhouse also protects plants from outdoor insects. Gardeners can also grow tropical plants that would not normally thrive in local environment. Some seedlings germinate throughout the winter and building indoor greenhouse is better option to provide better controlled environment than outdoor greenhouse. Before or after winter, the indoor greenhouse can also be useful if the garden is too crowded for a regular greenhouse.

Building Indoor Greenhouse

The most important is to decide on the indoor site. Once the site is decided, just make sure that there is electrical wiring suitable for at least one pair of fluorescent grow lights. Also remember that thermostat is always part of a greenhouse.


Next is to decide what type indoor greenhouse is most suitable. It is good to sketch out some plans before starting to build. Also get ready the proper tools such as hammer, nails, screws, screwdriver and even electric powerdriver or a power drill. Plywood for potting should be around 1 inch thickness. It is better to have it sanded on one side as this will diminish the amount of standing water on the wood.

Setting Up The Indoor Greenhouse

Next is to set up the shelves and attach the power strip to the middle of the shelf. It is good to use concrete blocks to slightly raise the shelf off the floor. It will provide the heat for the bottom of the pots to help the seeds germinate. Places beneath the shelf can also be used for storage.


Lights can then be hung from ceiling by light-weight chains so that they could be raised as the plants grow. Once this is done, the job of building indoor greenhouse is almost completed.


What need to be done is to hang clear plastic sheeting on the outside of each shelf to keep in warmth and moisture during winter months.
