Plant photosynthesis generally increases with irradiance until light saturation occurs. For example, increasing the angle of incidence (from perpendicular) at which light intersects the leaf surface decreases penetration depth and, ultimately, absorption. …

Mirrors help reflect light that plants need to grow. Mirrors are useful plant-growing tools because they can redirect light to places it is needed most. Mirrors also help plants thrive indoors, even in those small, dark corners and nooks where sunlight never seems to reach.

Reflected light is indirect sunlight that is bounced off reflective or light-colored surfaces, and it can still bring a lot of energy to your plants.

Blue light helps with the plant’s production of chlorophyll–the green pigment that traps light energy and is integral to photosynthesis. In other words, blue light is easier for a plant to absorb and use the energy in photosynthesis. So, blue light increases plant growth and makes the plant reach maturity faster.

Roots grow in the dark soil to anchor the plant and to absorb mineral nutrients and water. It has been reported that light can penetrate less than several millimeters due to the rather high absorbance of soil (Woolley and Stoller, 1978).

Summary: Light transmitted from the shoot to the roots activates photoreceptors in the roots and triggers light-dependent growth responses in plants, scientists have discovered.

Plants kept in dark places can hardly access any sunlight. As you know by now, plants use sunlight to make their own food. When the plant is in a dark room, it cannot photosynthesize and has not enough food left for the leaves to be healthy. Eventually, the plant dries up and dies due to a lack of sunlight.

Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.

As long as both wires of the cord (Hot and Neutral) are isolated from the exposed metal parts and isolated from coming in contact with the exposed metal parts of the lamp, there is no need for a ground. ELECTRICAL CONDUCTORS are types of material that allow the flow of electrical current in one or more directions.

If the fixture is out of reach, the lack of a ground is probably a low risk. Going without a ground wire When you screw the light switch in, it will make contact with the box, and as long as the box is grounded, it will pick up ground that way. If the box isn’t grounded, the switch will still work.

The ground wire doesn’t carry any electrical current (unless there is a problem in your electrical system). So if you wire your fan without the ground wire, it will still work properly. However, the added safety of the ground wire will not be present.

The two ground wires MUST be connected to preserve the ground on the remainder of the circuit. They should be wirenutted together along with a third short piece of bare or green wire of the same size, this becomes your pigtail.

Yes, just connect all the earth wires together in the appropriate terminal.

The only time two wires can be installed under a single screw or lug is when the terminal is identified for this purpose. Neutral and equipment grounding lugs for panelboards are often suitable for two and sometimes three wires.
