    the seeds i ordered say that the seeds will yield "400-500g m2" what exactly does that mean? Does it mean that ill have 400-500g per square meter of plants? If thats what it means, how many plants is a square meter?

    What they're saying is typical yield for the strain or variety is 400-500 grams per square meter of grow space, under optimal conditions of course.

    Not being up to par with my metric system, I'm unsure of the actual calculation, but there are metric conversion websites out there. I think it's somewhere between a square foot and a square yard :)

    okay, so how many plants do i need in the square meter in order to yield 400-500g?

    Impossible to predict, you should ask the breeder how he came up with his claim of 400-500 g/m2.

    okay, well it says that on basically every seed site. Itll say the seeds will yield X grams/m2.
    so does anyone else have any idea on how many plants they mean by "m2" or a meter squared?

    covered this at Cannabis Forums Message Boards - Marijuana Growing, Medical Marijuana, Cannabis Club, Dispensary, News RSS Feed - Marijuana Growing area - 500 gram m2, confused ??? : General Marijuana Growing


    saying:

    all the shops ive seen, doesn't claim 500grams per plant, its 500grm average per sqm..

    1 plant should have space of 1ft.

    1 m² = 10.7639 ft² OR 10 ft²

    6000 lumens per sqft for optimum growth, (sun gives 10000)

    =10 plants with lumens of 60,000 of lights should yield around 364grams.. depends on the light, nutrients and whether the farmer is tight.

    but if some people here are saying 2ounce per plant, then it will yield around : 560 grams.

    Over and over. Each plant is different how they grow. The Meter Squared is a constant that can be compared from one to the next.

    Those numbers are under perfect, I mean scientific-perfect growth. I have indicas, mixes, and sativas, and each produces about the same at the size I grow them. I will let an indica go longer in veg before flower as they don't have the growth spurt, which indoors can really cause some issues if you don't stay on top of things.

    Not only that, 6 growers growing out from the same mother, will not have the same production volume over the same time period. Variances in potting soil, nutrients, water hardness and included chemicals...

    IN summary,,,,,just a guideline.
