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.
Lighting Tips. Proper lighting duration is just as important as the light intensity. Tomatoes require at least eight hours of direct sunlight daily or 16 hours of artificial light per day. If you are growing seedlings indoors in spring when they don't receive eight hours of sunlight, you can supplement the natural sunlight with artificial light after sunset to equal 16 hours.
