I agree...
Pyramid Seeds should tell that more obviously.
We were right to be prudent before buying by Pyramid and all of you helped us not to make a mistake, thank you.
The seedbanks/breeders where we buy our seeds (past year and for 2013) give at least the yield weight per plant, and often the indoor expected yield (per plant or m²) AND the outdoor expected yield (per plant) : Philosopher Seeds, Dutch Passion, Royal Queen Seeds, Dinafem, AC Genetics, Paradise Seeds, Sweet Seeds, Short Stuff and Flash Seeds... for most of the varieties they sell.
And some breeders don't lie about the possible yield of their plant, for example we harvested 140g dried well manicured on a Rapid Afghan Auto in greenhouse, when AC Genetics tells we can hope to get 60-100g maximum outdoor in optimum condition...
