What does yield in g/m² mean?
Yield in g/m² (grams per square meter) is the approximate amount of dried buds a strain can produce per square meter of indoor growing space. It's the figure seed banks use to show whether a strain is more or less productive.
Imagine the floor of your grow tent divided into squares one meter on each side. The g/m² figure tells you how much you could harvest from each square, whether it holds one big plant or several small ones.
It's always measured in dried bud. A freshly cut plant weighs much more, because the buds are full of water and lose a good part of their weight as they dry.
What about yield in g/plant?
Outdoors, plants aren't grown under a lamp of a fixed size, but in the sun and often with plenty of space. That's why the yield is usually given per plant: how many dried grams a single plant can produce.
That figure depends enormously on how big the plant gets. A plant sown in the ground in spring with lots of sun can produce much more than the same strain in a small pot on a balcony.
What this figure means on a product page
On our product pages you'll see something like "Indoor yield: 400–500 g/m²" or "Outdoor yield: 500 g/plant". These figures come from the seed bank that created the variety, so take them with these caveats:
- It's the seed bank's guide, not a promise. It usually reflects good growing conditions and experienced growers.
- It depends on your grow. The strength of the light, the size of the pot, the climate, the growth time and how you care for the plants all have a big influence.
- It's mainly useful for comparing. If one strain states a higher yield than another, it will normally be more generous under the same conditions.
If it's your first grow, it's normal to harvest less than the product page says. With experience, you'll get closer to those figures.
