How plants get affected by too little or too much light?
- When plants lack light, they do not produce chlorophyll, and plants can turn pale green to yellow to white.
- Plant stems become “leggy,” meaning stems become long and thin and appear to be reaching toward the source of light.
- A lack of sufficient light causes the plant to grow long spaces on stems between the leaf nodes.
- Plants without more light may also drop their leaves, especially older leaves.
- Flowering plants may fail to produce flower buds.
- Plants exposed to too much light may result in burned and bleached leaves.
How to select the perfect spot for your plant?
- Filtered Sun: It describes the light close to a window that receives sun for about half of the day. It may also be the level of light in a sunny room behind a window curtain. It is the correct level for the plants that need a bright light, but not in the full blare of direct sun all day. It is light that is diffused between the plant and the light source.
- Light shade: It is the light level a bit away from a window in a room that receives sun for about half the day. It can also be in front of a window that receives no direct sunlight or in the corners of a sunny room.
- Shade: These are the areas where the windows receive no direct sun or limited hours of sunlight. The choice of plants that thrive in shade is restricted, but there are few that will survive including some ferns.
- Sun: The brightest light type, can be found in front of a window that gets over 12 hours of direct sunlight each day. Not many plants can survive with this intense light, especially in summer, although some like this position in winter when light is weaker.
- Full Sun: Area that receives 5 or more hours of direct sunlight daily. It is the brightest category of light for plants.
- Semi Sun: Area that receive only couple of hours of direct sunlight in winter. Balance time it receives indirect or reflected light.
- Semi Shade: Area that mostly receives good, bright, indirect light without any direct sun.
- Shade: Area that receives no direct sunlight; is mostly a bit dark even during afternoon.
Ways for increasing light levels for plants
a) Regular cleaning of leaves
b) Rotate your plants
c) Pay attention to light variations
d) Boost up low light conditions
e) Put them closer to a window or Door
f) Sunlight Bouncing Back
g) Place mirrors
