Here’s why: Not all plants are created equal:
Plant counts don’t count: It’s size that matters!
This plant produced under 3 grams (about 1/10 ounce) of cannabis bud.
At 9″ diameter; the dry whole plant weighed 9 grams, as shown in the photo.
The plant below produced more than 220 grams (almost 8 ounces) of cannabis bud
(the diameter was about 4.5′ in diameter, its actual canopy covered almost 16 square feet!)
That amounts to 64 times as much usable marijuana from this single plant
as from the plant above shown on the scale!
I have grown canopy plants that have yielded 2 lbs here in southern california. When i grew in northen oregon 4lbs plant yeilds where not uncommon but these where outdoor plants.
