Hi, I am not an accomplished outdoor grower, so take it with a grain, but applied science would tell me that using some kind of nute like Carboblast, or Bud chunk would help. Holland secret has one called Bud Start, which you apply one time when buds are about thumbnail size. It really chunks indoors ones up, and Holland secret has another good one called Ton o Bud, which goes on after the buds are established, almost until harvest. I am not sure how to compute the indoors application to outdoors, but it's the same plant. It should respond indoors or out. Any other opinions about that out there? does indoor technique apply to outdoors?
