How does light affect the growth of a plant?
How Light Affects the Growth of a Plant. Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow.
What effect does light have on plant growth independent variable?
Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable. They are also grown in the same sized pot and given an equal amount of water.
Do plants grow better in light or dark experiment?
ANSWER: In a strict sense, plants do not grow faster in the dark; they grow slower. However, plants seem to grow faster in insufficient light due to rapid cell elongation. In other words, they don’t grow faster, they simply stretch.
What kind of light do plants need?
Sunlight contains the complete spectrum of light including all colors of the rainbow: red through yellow to blue and violet. Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum.
Will any LED light work as a grow light?
Can Any LED Light Be Used As A Grow Light? LED lights are more energy efficient and emit much lower levels of heat than other types of lighting. But can you use any led lights to grow plants? Generally, yes.
What color light is best for plants?
Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.
What is the difference between a grow light and a regular light?
Grow lights produce more power than their regular counterparts. The intensity of the lights helps increase the rate of photosynthesis, as it ensures that the plants have sufficient energy to grow. There are different grow lights out on the market with different intensity levels that affect the power they produce.
What can I use instead of a grow light?
Artificial lighting:
- Fluorescent lights are by far the most economical and easy choice for houseplants.
- Incandescent lights give off a lot of heat and should be placed farther away from plant foliage.
- LED lights are also a low heat, energy-efficient artificial light source.
Can I put a grow light bulb in a regular lamp?
Yes. If the regular lamp has the correct socket type and wattage capacity, a grow light bulb should fit into a regular lamp without any problems.
What kind of light is best for vegetative growth?
Blue light
How much light is in the vegetative stage?
When marijuana plants are in the vegetative stage, keep them under a minimum of 18 hours of growing light (also known as 18/6). But if you are one of those growers that would like their plant to grow as big as possible, then you may keep them under 24 hour (24/0) indoor light.
What wavelengths of light do plants not use?
Plant Light Wavelengths Once seeds have sprouted, both blue light and red light, with 650-nm wavelengths, are essential for photosynthesis. Without blue and red light, the plants are not able to produce food.
What type of light is best for growing Marijuanas?
blue light
Can I leave my grow light on 24 hours?
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
How many plants can a 1000w LED light grow?
How Many Plants Can I Grow?
| Grow Space Size | Minimum Number of Watts Required | Number of Plants You Can Grow |
|---|---|---|
| 9 sq ft (3×3) | 450w | 1-9 plants* |
| 12 sq ft (3×4) | 600w | 1-12 plants* |
| 16 sq ft (4×4) | 800w | 1-16 plants* |
| 20 sq ft (4×5) | 1000w | 1-20 plants* |
What lights do professional growers use?
Today, the most widely used lights for professional use are HIDs and fluorescents. Indoor flower and vegetable growers typically use high-pressure sodium (HPS/SON) and metal halide (MH) HID lights, but fluorescents and LEDs are replacing metal halides due to their efficiency and economy.
What is the best wattage for grow lights?
Once you’ve decided which kind of plant grow light you want, it’s time to decide how big a bulb you need for the space you have. First, determine how much space you need to illuminate. As a rule, you want 20 to 40 watts per square foot.

How many lights do I need for 12 plants?
The minimum you want to use the entire room would be 4x600w lights this would give you room enough to get in around the plants at watering time etc. But in all honesty depending upon how much you would like to achieve (grams wise) you could grow 12 medium sized plants under 2x600w lights and section the room off.
How many hours should grow lights be on?
16 hours
How far away should light be from plants?
12″
Does more light equal more yield?
In essence yes MOAR light equals more yield but at a point there is to much.
Does Vegging longer increase yield?
The longer you keep your plants in the vegetative stage, the bigger your plant will be, resulting in bigger yields from plants that were vegetated longer. Most people veg their plants anywhere from 2 weeks to 2 months but there are Sea of Green growers who hardly veg at all and large plant experts that go longer.
Should I remove fan leaves during flowering?
Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.

Does Topping increase yield?
Does topping really increase yield. Some people claim topping does not actually increase yield, because the colas get smaller every time you top. But, it has been shown that the cumulative yield is much heavier when you top your plants. So yes, topping really increases yield.
