If you want to keep the lights above the surface of the soil, you have to move the lamp upward. When the plants are about 6-8 inches tall, you can transplant them into a pot with a drainage hole in the bottom. This will allow the water to drain away from the roots and keep them from drying out. If you don’t have drainage holes in your pot, then you will have to dig a hole and fill it with water.
You can use a garden hose to do this, but it will take a while to fill the hole, so you might as well do it the old-fashioned way. Once the plant is about 8-10 inches in height, it’s time to move it to a larger pot. It will need to be at least 12-14 inches high, depending on the size of your plant and the type of soil you are growing it in.
Make sure that the pot is large enough to hold the entire plant, and that you have enough room for the root ball to grow. The plant should be able to stand up on its own without support.

Do grow lights need to be directly above plants?
Place grow lights directly over plantings to mimic natural sunlight. The grow light bulbs should be at least 24 inches over the plants. The lights can be placed 12 and 6 inches away from the plants, because they have a lower heat signature.
If you’re growing in a greenhouse, you’ll want to place your lights closer to the top of the greenhouse than you would in the ground. This will allow the light to reach all the way up the sides of your greenhouse.
Where should grow lights be placed?
It’s a good idea to keep the grow lights away from your plants at all times. If you have a 1000 watt light, you may want to hang it at the back of your grow room.
If you’re using a grow light that has a built-in dimmer switch, make sure you turn it off when you leave the room, otherwise it’ll be too bright for the plants.
If you don’t have one of these, you can use a timer to turn the lights off after a certain amount of time, then turn them back on when the timer goes off.
Can LED grow lights burn plants?
The reality is that modern LED grow lights can produce a very high level of light and it can cause photo-bleaching and burn leaves. This depends on the plant, but a PPFD of 800 is enough to cause the leaves to turn brown. If you have a plant that is very sensitive to light, you may want to consider a different grow light.
The answer to this question depends on a number of factors, including the type of plant you are growing, the size of your grow space, and how much light you need. For example, if you’re growing a large plant in a small space (like a greenhouse), you’ll need more light to grow the same amount of plants.
On the other hand, a smaller plant will need less light than a larger plant. The best way to find out is to experiment with different types of lights and see which one produces the best results for your particular situation.
How do you tell if grow light is too close?
White or yellow spots on the leaves and stems are a sign that your light is too close to your plants. This can be caused by a number of factors, including too much direct sunlight, too little shade, or a combination of both. – Typically indicates the amount of light your plant receives from the sun.
Too little light can lead to leaf discoloration, which can make it difficult for the plant to photosynthesize and produce chlorophyll, the pigment that gives plants their green color. Light that’s too bright can also cause the plants’ leaves to turn yellow, making it hard for them to absorb enough light to make photosynthesis happen.
If you notice any of these signs, it’s a good idea to switch to a different type of lighting, such as a CFL or LED, to avoid any potential problems.
Can you leave grow lights on 24 hours a day?
You shouldn’t leave grow lights on all the time. Plants need a light-dark cycle to grow. It’s believed that they take care of the rest of their needs while resting during periods of darkness, and that they use this time to move nutrition into their limbs. 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 location.
Are purple grow lights better?
LED fixtures that emit a purplish light are usually less preferred by people, but are often the most efficient at converting electricity into usable light.
How many hours should a grow light be on?
To be effective, grow lights need to be on for at least eight hours a day. Depending on the conditions, this can be as long as 16 hours. It’s best to use an energy efficient type of grow lights when they have to be left on all day.
If you want the light to be overhead, position the grow light above the plant. If you’re growing indoors, you’ll want to make sure that you have a good ventilation system in place. The fan will draw air in from the outside, which will help to keep the temperature of your grow room at a comfortable level.
If you don’t have an air conditioner in your room, then you can also use a humidifier to help with the humidity. Humidifiers can be purchased at most home improvement stores, and they will work just as well for indoor growing as they do for outdoor growing.
