1. Masks are contaminated with foreign materials such as blood stains or droplets
2. The user feels greater respiratory resistance;
3, masks are damaged.
Dust filter cotton, in the mask and the user's face close to a good case, when the user feels a great breathing resistance, indicating that the filter cotton has been covered with dust particles, should be replaced.
Antivirus cartridges, when the mask is in close contact with the user's door, should be renewed when the user smells toxic.
The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two surfaces cannot be used interchangeably. Otherwise, the dirt contaminated by the outer layer will stick directly to it. When inhaling the human body, it becomes a source of infection. When the mask is not worn, it should be folded and placed in a clean envelope. It should be folded tightly against the side of the mouth and nose. It should not be stuffed in the pocket or hung on the neck.
If the mask is moistened with exhaled hot gas or saliva, the effect of blocking the bacteria will be greatly reduced. Therefore, it is best to prepare more masks at ordinary times so that they can be used alternately. They should be changed once a day. Washing should be done with boiling water for 5 minutes, and then gently scrub, rinse with water and expose it to the sun. However, there is activated carbon filtration and disposable cleaning.
Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although LED Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED grow lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.
Yields! With a quality Grow light and an average-to-good grow,you can expect yields of about 0.5g/watt. It depends a lot on strain,and pro growers can yield even more,but that's a good rule of thumb.As an example, a 200W LED (200W true power draw, not an "equivalent" wattage) would yield about 100 grams on average, or 3.5 ounces
