how big is a m2?

My afghan kush says 400 grams per m2 but i have no clue how tall a m2 is .. like hown many inches vertically is a m2? Cuz i want that 400 grams at least but I don't kno what height to start flowering at if i don't kno how tall a m2 is vertically. . If someone can tell me how tall a m2 Is I'll b able to get that 400 grams probably more because i topped my baby twice and I'm going to lollipop it and i just ordered some nutrients and will probably add more lights

M2 means square meter. About 10 square feet.

He only has the one. He's going to be very disappointed.

I would guess M2 = meters squared. So it will depend on how you train your plant. If it's really wide, it doesn't have to be very tall. I would think M^3 would be a better way to determine yield, but that's just the scientist talking.

It is referring to floor space, not vertical height. As @warble said, it's ~10sq feet.

3-4 zips now I'd b a happy camper with that. .

If you want to achieve 3 to 4 ozs per plant , you are going to need at minimum a 600W HPS light .

""400 grams probably more because" i topped my baby twice" and I'm going to lollipop""
2, 2.5 oz each plant with a 600. More tops more bud bigger the plant more it will yield

maybe 4 oz plant

I use a 600W light , doing 3 plants at a time and I get 4 ozs per plant on average . I have a perpetual grow and pull about 12 oz every 4 weeks. I do three plants every four weeks.

Bahahah . I love when people make threads and then fight the answers.

Op. 400 grams is like 14 ounces. You aren't going to get that off one plant. Seed companies don't say your going to get that off one plant they say you can achieve that if you have a full square meter of canopy. And just because it says that, doesn't mean your going to achieve it. Growing weed isn't easy, requires a lot of time and patients and research. Invest the time and research before you go wishing with hopes and dreams.
