Plants need a daily respiration period of at least 6 hours per day for seedlings and at least 10 hours for more mature plants. We don’t recommend giving more than 14-16 hours per day of light, even if you are growing long-day-loving varieties and trying to induce growth. We recommend that you provide your plants with a minimum of 12 hours of direct sunlight each day.
This is the minimum amount of sunlight that plants need in order to be able to photosynthesize and grow. However, you should be aware that this is not always the case. For example, it is possible to grow plants that require much more light than this, such as sunnier varieties.
In this case, we would recommend using a light schedule that allows for the plants to get enough light for photosynthesis, but not so much that they are unable to take in sufficient amounts of water to keep them hydrated.
If you have a plant that requires more sunlight than the recommended amount, then you will need to adjust your lighting schedule to ensure that the plant gets enough of the light that it needs to survive.

Can you leave a grow light on too long?
You should not leave grow lights on all the time. Plants need a light-dark cycle to grow. During periods of darkness, it’s believed that they use this time to move vitamins and minerals into their bodies. If your plants look like they’re ready for transplanting, then you’re good to go.
If they don’t look ready, it’s probably best to wait until the next growing season to transplant them. This is especially true if you plan to grow more than one plant at a time, as you’ll need to make sure that all of your transplants are grown in the same environment.
When should I turn my grow lights on?
Your grow lights should be turned on when the first seed starts to grow. Many types of seedlings grow very quickly, and they will reach for the light as soon as they emerge. From the beginning, give them plenty of it. If you don’t have a grow light, you can still grow your seeds indoors, but you’ll need to do a little more work to get the best results.
Is 12 hours of grow light too much?
It is ideal to keep a grow light on for about 12 to 18 hours. A weed plant’s natural process of growth and dormancy can be interrupted by too much light. Light exposure for a long time can damage the plant. The best time to grow marijuana indoors is during the growing season, when the temperature is cooler and the humidity is higher.
During this time, the marijuana plant will be able to take in more light and nutrients from the air. This is especially important for indoor growers who want to maximize the amount of plants they can grow at one time. If you are growing marijuana in a greenhouse, you will need to make sure that your grow lights do not get too close to the plants, as this can cause them to overheat and die.
Do grow lights use a lot of electricity?
40W grow light that is on for the same number of hours will cost me 2.3USD/month in electricity. All grow lights consume a certain amount of electricity, and the more electricity you use the bigger your bill will be. The best way to save money on electricity is to grow your own food.
This will save you a lot of money in the long run, as you will not have to buy food from the grocery store every time you want to plant a new plant. You will also be able to keep your food fresh for longer periods of time, since you won’t need to refrigerate it.
If you don’t have access to fresh produce, you can always buy it from your local farmers market, which is a great source of fresh fruits and vegetables.
Do plants need darkness to grow?
Plants, shrubs and trees use sunlight during the daytime, but at night they need darkness to regenerate a key compound. Nighttime lighting can affect the ability of vegetation to create this compound.
The study, published in the Journal of Experimental Botany, found that when plants were exposed to artificial night-time light, their photosynthetic activity was reduced by as much as 50 per cent. The researchers this is the first time this has been shown to occur in a plant species.
Do plants grow faster with more light?
Sugars fuel plant growth because the more light a plant is exposed to, the more energy it will create and the higher its output will be. In the case of solar panels, this is because the sun’s energy is absorbed by the glass, which absorbs the light and converts it into heat.
This process is called photovoltaic (PV), and it is one of the most efficient forms of energy generation in the world. PV is responsible for more than 40 percent of all electricity generation.
