Indoor Yield Estimates

Indoor yields are often expressed in grams per watt (g/W) of light used. A well-managed indoor grow can achieve yields of 0.5 to 1 gram per watt, or even higher with advanced techniques. For example, a 600-watt grow light could potentially yield 300 to 600 grams of dried flower per plant.

Another common metric is yield per square foot. In a well-optimized indoor setup, you might expect to harvest 1 to 2 ounces (28 to 56 grams) of dried flower per square foot of grow space. This estimate depends on factors such as plant density and the specific strain. Remember, these are just estimates, and actual yields can vary significantly.

Outdoor Yield Estimates

Outdoor yields are more variable due to the influence of weather and environmental conditions. A healthy outdoor plant can produce a significant amount of dried flower, potentially yielding several ounces or even pounds. Yields can range from a few ounces to several pounds per plant, depending on the size of the plant, the strain, and the growing season. Factors like sunlight exposure, soil quality, and the length of the growing season will significantly impact the final yield.

It’s important to note that these are estimates, and actual yields can vary. Experienced growers can often achieve higher yields than beginners. Proper planning, meticulous attention to detail, and a commitment to learning and adapting are crucial for maximizing your harvest.

Yield Calculation Tools

Several online yield calculators can help you estimate your potential harvest. These tools typically ask you to input information about your grow setup, such as the size of your grow space, the type of lighting you use, and the number of plants you intend to grow. They then provide an estimated yield range based on this information. While these tools can be helpful, remember that they are based on averages and estimations, and actual results may vary.

These calculators can be a good starting point for planning your grow. However, always take the results with a grain of salt. The best way to improve your yield estimates is to track your results over time and learn from your experiences. Record the strain, the growing conditions, and the final yield of each harvest.
