Indoor vs Outdoor
Cannabis plants can be grown indoors or outdoors, depending on the climate and space available. Many indoor growers use hydroponic systems to ensure a constant supply of water and nutrients to the roots, as well as control over the growing environment.
The number of cannabis plants that can be grown per square foot will depend on the method of cultivation. Indoor growers using hydroponic systems can typically grow more plants per square foot than those growing in soil, as they have greater control over the root environment.
Outdoor growers may be limited by the amount of space available, as well as the climate. In cooler climates, it may not be possible to grow as many plants per square foot due to the shorter growing season.
Plant Sizes
Plants come in all shapes and sizes, from miniature potted plants to towering trees. The size of a cannabis plant will depend on several factors, including the strain, the growing environment, and the amount of nutrients and water available.
In general, however, there are three main categories of cannabis plant size: small, medium, and large. Here is a breakdown of the average size of each category:
Small: Less than 2 feet tall with a thin stalk. Small plants are typically easy to handle and require less maintenance than larger plants.
Medium: Between 2 and 4 feet tall with a thicker stalk. Medium-sized plants may need more attention than small plants, but they are still relatively easy to care for.
Large: More than 4 feet tall with a thick stalk. Large plants can be difficult to manage, especially if they are not well-rooted. They may also require more nutrients and water than smaller plants.
Yields Per Plant
The average cannabis plant will produce between 1 and 4 ounces of usable weed. But experienced growers have gotten outdoor plants to produce as much as a pound, and indoor growers have pulled multiple pounds per square meter from a single plant.
So, how many Cannabis plants per sq ft?
sq ft is the optimal spacing for most cannabis strains. This allows the plants to get adequate airflow and prevents the leaves from shading each other, which can lead to mold and bud rot.
In general, you can expect each cannabis plant to yield about 2-4 ounces. But there are many factors that can affect yields, such as:
– The type of cannabis strain you are growing
– The size and shape of your grow area
– The number of hours of artificial light per day
– The quality of the soil, water and nutrients you are using
– Your level of experience as a grower
With that said, here are some general guidelines for estimating yields per square foot:
-If you are growing in soil, each plant will yield 2-4 ounces.
-If you are growing in hydroponics or coco coir, each plant will yield 4-6 ounces.
-If you are growing in an SOG (sea of green) setup, each plant will yield 6-8 ounces.
Square Footage
The size of your grow area will ultimately dictate the number of cannabis plants you can grow. But, how much space does each plant need? It depends on the size and type of cannabis you want to grow. We’ll give some general recommendations below, but remember that these are just guidelines – you may need to adjust based on your specific situation.
Indoors, most growers use between 1-2 square feet per plant. So, if you have a 10×10 growspace, you could comfortably fit between 16-25 plants. Of course, if you’re growing smaller plants (like autoflowers), you could probably fit even more. And, if you’re growing larger plants (like sativas), you may need even less space.
Outdoors, each plant can easily take up 10 square feet or more. But, again, it depends on the type of cannabis you’re growing and the size of the final plant. So, if you have a 10×10 grow area, you could probably only comfortably fit 1-4 plants.
Keep in mind that these are just general recommendations – your specific grow situation will dictate how many plants you can actually fit in your given space. But, hopefully this gives you a good starting point to work from!
Conclusion
In general, you can expect to yield around 0.5 to 1 gram of bud per watt of light. So, a 1000-watt grow light will yield between 500 and 1000 grams (or 1 and 2 pounds) per square foot of grow space. But keep in mind that there are many other factors that affect yield, such as plant strain, growing medium, nutrients, and more.
