Growing plants indoors under lights extends your gardening season through the winter and often lets you grow a wider variety of houseplants than with ordinary daylight. Innovations in the lighting industry make it possible to grow plants in unexpected locations and lets you get a start of spring by growing your own seedlings for the garden. Rig growing lights to bring the outdoors inside, without making drastic changes to your decor.
Assess your growing spaces. Ideally, your growing lights will supplement existing daylight; it requires sticking to a strict schedule to grow plants in a below-ground rec room or windowless corner because you will be providing all the light your plants receive. Scout out north-facing windows with wide sills or set a table under a window where you usually draw the drapes at night. Plan to mount lights between 18 and 24 inches above plants (err on the side of increasing rather than decreasing distance between light fixtures and plants, to prevent possible excess heat).
Assess your lighting options. Grow-lights, also sometimes called full-spectrum lights, are available both in fluorescent tubes and screw-in bulbs. Gardening supply catalogs offer the option of tables that come with light sets; some assembly required. Do-it-yourselfers can mount light brackets in the soffit over a bay window, behind the deep valance heading drapes, or as a replacement for the over-the-sink kitchen light fixture. A small area can be lighted by mounting a wall bracket and clamping on a coolie-shaded corded work light.
Mount lights over your planting area. Remember that your new lights will stimulate greater growth than darker areas, which means that you might find plants using additional water. Check soil frequently to make certain you are keeping up with new requirements.
Plan to provide regular nutrition to your growing plants. Now that you have improved growing conditions, providing food to support plant growth will keep plants strong and healthy.
Resist the impulse to keep lights on 24 hours a day when the weather is gloomy and dark. Like other living creatures, plants need dark rest times for proper growth. Turning lights on when you rise and off when you go to sleep maintains their customary daily cycle. Excessive light produces stress and fatigue.
