sure it's correct.
you need to go to their website & see if they note how those #s are reached... so big a pot, so much veg, flipped at such a height, so much wattage, etc.
plus, "pato" from kannabia is accessible.
he'll email you, little slow but he gets back.
i dont run his genetics but oddly have had several current email exchanges with him about his gear i got free in a seed purchase.
pato worked at sensi seeds under shantibaba... so he & his genetic stock are old school & very legit.
& cool people ...speaks & wirtes real good english.
id say 350g indoor & 500g outdoor... & that would most likely be a yield based on a square meter.
im growing super skunk now... different breeder.
