I guess, no response, means, NO to any outdoor northern Karma strains!
sorry must have mist your question.
I cant give a solid answer to this, as there is not anouf expierence with growing my indoor strains outdoor in Norther Hem.
I dont wanne give you advice on a Belief, then hard proof.
Most strains have been grown outdoor Tho but in south spain which alows most stuff to be grown outdoor easy.
I do know that when we Grew my OG's in holland we had mold on the Bear OG (Karma OG these days)
My advice would be to check out Esben's stuff Hybrids From Hell his company called, he specialized in Northern hems. outdoor hybrids.
