Lights for Long Day plants and additional growing space

Long-Day Plants

Long-day plants, as a rule, need 14 or more hours of light per day to develop good flowers. In winter when days are short, give these plants 4 to 6 hours of added light. Sixty to 75-watt incandescent, as many as needed, are spaced 3 feet apart and hung about 4 feet above the plants. They will supply the right amount of light.

Asters, dahlias, delphinium, feverfew, some varieties of iris,

marigold, pansy, stock, and tuberous begonias are some of the plants which respond favorably to artificial day lengthening.

Additional growing space

If you want still more room, add fluorescent light setups to the dark areas of your house and turn them into plant-growing spaces. Basements, attics, closets, windowless walls, utility rooms-all become propagation areas when supplied with fluorescent lighting. These lights work on ordinary household current. However, before installing more than a pair or two of them it would be wise to check with your electrical company to find out if your present electrical wiring can stand the additional load.

If you need only a small additional propagation area, you may find it advantageous to buy one of the commercial fluorescent light stands with two to four shelves. A model with three shelves holds two hundred 3-inch pots. There are models available with or without wheels.
