Indoor vs Outdoor
If you’re growing cannabis, you need to know how many plants per light you can grow. The answer depends on whether you’re growing indoors or outdoors. Let’s get into the details.
Indoor
Cannabis plants grow best in a sunny location with at least six hours of direct sunlight per day. If you don’t have an outdoor space that gets enough sunlight, you can grow cannabis indoors under artificial lights.
Indoor growers have more control over the growing environment, which means they can produce higher quality cannabis. However, indoor grows are more expensive and require more time and effort to set up and maintain.
##How Many Cannabis Plants Per Light?
The number of cannabis plants you can grow under each light will depend on the type and intensity of the light, as well as the size of your growing space. In general, you can expect to yield about 0.5 grams per watt of light. So, a 1000-watt light will produce about 500 grams (or 1 pound) of usable cannabis per harvest.
Soil
One of the biggest decisions you need to make when setting up your cannabis grow room is deciding whether to grow in soil or hydroponics (a.k.a. water culture). Both have their pros and cons, so it’s important to understand the difference before making a decision.
Soil is the most natural way to grow plants, and most plants can be grown in soil with no problems. Cannabis is no different – it can be grown in soil quite easily. The big advantage of growing in soil is that it’s easy to set up and doesn’t require any special equipment. You can simply put your plants in some potting mix and they should do fine.
The disadvantages of growing in soil are that it can be messy, and you need to be careful not to overwater your plants. If you overwater them, they can develop root rot, which can kill them.
Hydroponics is a method of growing plants in water instead of soil. The advantages of hydroponics are that it’s very efficient – you use less water and less space than you would if you were growing in soil. Additionally, it’s easier to control the nutrients that your plants are getting, which means that they can grow faster and healthier.
The disadvantages of hydroponics are that it requires more equipment than growing in soil, and it can be more expensive to set up. Additionally, if something goes wrong with your hydroponic system, your plants can die very quickly since they don’t have any roots in the water to absorb nutrients from.
Hydro
Plants need light to grow, and the more light they have, the faster they will grow. Cannabis plants are no different. However, there is a limit to how much light a plant can use, and that limit is dependent on the intensity of the light. So, how many cannabis plants per light?
The answer depends on the type of light you are using. For example, if you are using a 400-watt HPS (high-pressure sodium) lamp, you can expect to grow about 4-6 plants under that light. If you are using a 600-watt HPS lamp, you can expect to grow about 6-8 plants under that light.
However, if you are using LED (light emitting diode) grow lights, the number of plants you can grow will be much higher. For example, if you are using a 300-watt LED grow light, you can expect to grow about 8-10 plants under that light. If you are using a 500-watt LED grow light, you can expect to grow about 10-12 plants under that light.
So, how many cannabis plants per light? It depends on the type of light you are using. If you are using HPS lights, you can expect to grow 4-8 plants per light. If you are using LED lights, you can expect to grow 8-12 plants per light.
Outdoor
If you are growing your plants outdoors, you will be able to get away with fewer plants per light. This is because the sun provides a much more intense light than any grow light on the market, giving your plants all the light they need to grow big and strong.
That being said, you will still need to take into account the size of your grow area and the amount of sunlight that it receives. If you are growing in an area that doesn’t get a lot of sun, you will need to compensate for this with more lights or by using a grow light that is more powerful.
In general, you can expect to yield around 1 gram of flower per watt of light when growing outdoors. So, if you are using a 1000 watt light, you can expect to yield around 1000 grams (1 kilo) of weed.
How Many Plants Per Light?
When it comes to growing cannabis, one of the most common questions is “How many plants can I grow per light?” The answer to this question depends on a few factors, such as the type of light you’re using and the size of your grow space. In this article, we’ll give you some general guidelines to help you determine how many plants you can grow per light.
Indoor
The average number of plants that can be grown under one 600-watt light is five to six. However, the number of plants that can be grown will also be determined by the size of your growing space and how you utilize that space. If you are growing in a 4’x4’ grow tent, for example, you will likely only be able to accommodate four plants due to the lack of space for them to spread out. In this case, you would either need to increase the size of your grow room or decrease the number of plants per light.
Soil
When growing in soil, you can expect to yield anywhere between 0.5 to 1 gram of dried bud per watt of light. So, a 1000 watt HPS light will give you 500-1000 grams, or just over 1 pound of weed. This is a general range, and your actual yield will depend on other factors like nutrients, training methods, and phenotype (the plant’s genetics).
Hydro
The size of your grow op will determine the number of lights you need, as well as the type of light. A general rule of thumb is 50-60 watts per square foot, but this will depend on the type of light (LED, HPS, MH, CMH, etc.), the efficiency of your reflectors, and your desired canopy density. Once you’ve figured out how much power you need to provide to your grow op, it’s time to determine how many plants per light you can grow.
For obvious reasons, cannabis plants need light to produce buds. The amount of light a plant needs depends on the stage of growth. Seedlings and clones need very little light – around 20-40 watts per square foot – because they are not yet producing buds. Once plants enter the vegetative stage, they need more light – around 40-60 watts per square foot – because they are growing leaves and stems. Once plants enter the flowering stage, they need even more light – around 60-80 watts per square foot – because they are producing buds.
So, how many cannabis plants can you grow per light? It depends on the stage of growth and the size of your grow op. For example, if you have a 4’x4′ grow op with two 1000 watt lights, you can grow 8-16 plants in the vegetative stage and 4-8 plants in the flowering stage. If you have a 8’x8′ grow op with four 1000 watt lights, you can grow 16-32 plants in the vegetative stage and 8-16 plants in the flowering stage.
Remember, these are just general guidelines. Your actual number of plants per light will depend on many factors, including the type of light (LED, HPS, MH, CMH), your reflectors’ efficiency, your desired canopy density, and more.
Outdoor
The average number of cannabis plants that can be grown per light outdoors is 10-20. It all depends on the size of the light, the size of the area, and the intensity of the light.
