How to Estimate Cannabis Yield in Canada

The Seennabis Yield Calculator estimates your harvest based on grow space dimensions, lighting type and wattage, growing medium, seed type (feminized or autoflower), and experience level. Indoor growers using LED lighting can expect roughly 0.5 to 1 gram per watt with proper training, while HPS setups average 0.5 to 0.75 grams per watt. Canadian outdoor growers in optimal climates can harvest 1 to 3 pounds per plant with large photoperiod strains in southern Canadian regions, while northern growers often prefer fast autoflowers that finish before September frost.

Factors that influence yield include training techniques like LST, SCROG, and topping, nutrient quality and feeding schedule, pot size and root space, light penetration and spectrum, and genetics. High-yield strains in our marketplace are tagged with yield data from verified Canadian growers so you can compare expected harvests before buying seeds, with all listings priced in CAD.
