Prompt Title: Cannabis plants per acre?

Based on the provided web search results, the number of cannabis plants that can be grown in an area of 1 acre can vary widely depending on several factors, including the size of the plants, the growing conditions, and the type of cultivation method used.

One source suggests that growers generally plant 2,600 to 5,800 plants per acre in single rows with 18 to 30 inches between plants in the row on 5.0- to 6.5-foot centers [7]. Another source suggests that on a small to medium scale, 1 to 2 plants per square foot can yield around 2 to 3 ounces of cannabis per square foot [8]. In a hydroponic setup, growers can use five-gallon buckets that take up about 2 square feet of space, and they can pack their grow room with these buckets to grow high-quality cannabis [10].

However, the number of plants that may be grown and the amount of dried marijuana that can be stored is limited and based on a formula that takes into account the daily amount authorized by the healthcare practitioner and the average yield of a plant under certain growing conditions, such as indoor or outdoor growing [4]. In Ontario, individuals are allowed to grow up to four cannabis plants per residence (not per person) for personal use if the starting material was purchased from the Ontario Cannabis Store or an authorized retail store, and it is not forbidden by their lease agreement or condo rules [1].

Overall, the number of cannabis plants that can be grown in an acre will depend on several factors, including the cultivation method used, plant size, and the growing conditions. It is important to comply with applicable laws and regulations when growing cannabis.
