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.
So if you find you are getting heavy growths of algae you can simply cut back on the amount of time the light is on and/or add algae eaters. If you have a freshwater planted tank or a reef aquarium most people recommend running your lights for 8-12 hours per day. This should give your plants or corals plenty of time for photosynthesis. No matter what type of tank you have the use of a timer to turn on and off your lights is recommended.
