I know i might be over thinking this but what exactly does it mean when it says x strain will yield : about 450 gr/m2 ? what does the /m2 stand for ?
Hi. M2 stands for Meters squared. So, a meter is approx 3 feet (a little bit less). So the calculation will be 3' x 3' = 9 sq ft. Freak
It means they really want you to buy their seeds. Coincidentally, I am sure, 450 grams works out to exactly one pound. It's the theoretical yield of a Sea of Green (SOG) style grow under ideal growing conditions: perfect lights, nutes, temps, humidity, CO2 level. Go look up some of Rumpleforeskin's grow journals to see what a grow like that looks like, but don't go by his recent LED experiments. Here are some highlights.
