1 M2=appx 10ft2, or just larger than a 3'x3'area horizontally not vertically. 1 GPW( Gram Per Watt) is what most people shoot for, and most never get there, you'll get closer to .25GPW on your first run until you get used to it..soo about 100G or 4 oz off that 400 your first run.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
Breeders list their yields/potency from the best plant they grew out of possibly hundreds, grown under optimal conditions. That 400G in a M2 is probably under a 1000W light.
Your vertical height will be determined by your height under your lights, plants will stretch 2-3X their size when they flower, so if you have 40" of flowering height total you'd want to start your flowering when your plants are appx 10-12" tall, but in your situation that wouldn't be good because the 400W light won't penetrate 20+'"into the plants.
Does time matter or are you willing to veg them out for a little longer? If you SCROG 2 plants in a 3'x3' area under the 400, keep your canopy depth to around 12" to get full penetration from that 400, learn your strain by growing it for a couple cycles and keep your environment decent you might consistently get 10 oz+ out of it.
