How Much Cannabis Can I Yield Per Plant?

Cannabis Yield Per Plant   When I get this question, I like to ask a question back . . . How long is a piece of string?

   The answer is that it depends.

   When growing cannabis indoors, every grower wants to get the biggest yield possible from their plants. Growing methods such as in soil or hydroponics, quantity and quality of lighting used, temperature, humidity, and nutrients all play a big role in the final dry weight.

   Another very important factor in cannabis yield per plant is in strain selection – some strains naturally yield more than others.

   When you have all of these external factors dialed-in, here is what you can expect for results.

   From The Weed Blog:

Imperial

  • An average of around 1.5 to 2.0 oz (3.5 oz for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 3.0 to 5.0 oz (9.0 oz for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 4.5 to 9.0 oz (14 oz for advanced growers) with a 400-watt HPS lamp in a grow room that measures 3.5 x 3.5 x 7 ft.
  • An average of around 5.0 to 10 oz (21 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 4 x 4 x 8 ft.
  • An average of around 250 to 500 grams (1000 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 5 x 5 x 8 ft.

Metric

  • An average of around 40 to 60 grams (100 for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 1 x 0.5 x 2 m.
  • An average of around 80 to 150 grams (250 for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 1 x 0.5 x 2 m.
  • An average of around 100 to 250 grams (400 for advanced growers) with a 400-watt HPS lamp in a grow room that measures 1 x 1 x 2.5 m.
  • An average of around 150 to 300 grams (600 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 1.2 x 1.2 x 2.5 m.
  • An average of around 250 to 500 grams (1000 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 1.5 x 1.5 x 2.5 m.

   You will notice that yield expectations above are based on CFL and HPS lighting. While that kind of lighting certainly works and has been tested for decades, we firmly support LED Grow Lights for cannabis. LED has come a long way over the last 5 years in terms of yield and crop quality. Growers report 7-14 day reduction in finishing time and an increase in THC content of 15-25%.
