Growth of Plants in Artificial Light

Abstract

A great variety of plants, including wheat, oats, barley, rye, flax, buckwheat, white sweet clover, peas, beans, lettuce, and a number of common weeds were grown from seed to maturity in continuous artificial light, and all set good seed. Potatoes, tomatoes, red clover, alsike clover, squash, and Silene bloomed, but did not set seed. Potatoes produced tubers of good size. All of the plants tested did not require a certain period of illumination to cause them to bloom. It is possible to produce seed from plants in winter independent of sunlight, and at no very great expense.
