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.
Vegetable seedlings need 14-18 hours of light a day. Botanists usually divide plants into three categories relating to their preferred day length: short-day, long-day or day-neutral. Short-day plants, such as chrysanthemums, kalanchoe, azaleas and begonias, will thrive on less than 12 hours of light per day. In fact, these plants must usually go through a series of even shorter days before they will set buds and flower. Long-day plants require at least 14 to 18 hours of light each day.
