While growing in absolute size, however, folk religions, Judaism and âother religionsâ (the umbrella category considered as a whole) will not keep pace with global population growth. Each of these groups is projected to make up a smaller percentage of the worldâs population in 2050 than it did in 2010.
Cycle the grow lights on and off appropriately. You cannot maximize plant growth by simply leaving the grow lights on 24 hours each day. In fact, this is a good way to stress and kill your houseplants. Instead, aim to leave grow lights on continuously for about 14 to 16 hours each day, which simulates spring sunlight.
Give a plant too much sun and it will look bleached, pale, or event burned; too few hours and it will have thin leaves and elongated shoots. Some plants require about a half day of light, while others need up to 18 hours of light each day; the latter include vegetables, which will get pale without sufficient light. Still others, such as African violets, need only about eight hours of light per day year-round. Many indoor plants might get a few hours of direct sun each day, but the angle at which the sun hits a window can be undependable. And natural light isn't strong or long enough to grow herbs or vegetables indoors.
