Hennesy, what an idiotic suggestion.... keep them in the dark for a week? You ARE killing them in a detrimental way by doing that. I think maybe you want to not water or feed them for the last few weeks too? And put them in a vacuum? You want to deprive them of light? Why not food water and air as well?
IamStoned, value Razz's advice, ignore 90% of what Hennessy1414 advises. If you dont believe me, ask Razz. Have a look through the gallery photos and posts by Hennessy1414, and then Razz, and then me. You have more photos of growing cannabis than he does. Razz and I (and others here) have galleries and posts full of thick lush cannabis, nice hash, ect. If you would rather take advice from someone with no demonstrated experience with growing or hashmaking who comments on everything anyway, then Hennessy1414 is your guy.
MH is good for veg and the first week or 2 of flower only, after that HPS is better for finishing the crop. Whenever you start the flush, be sure to do it for a week minimum, 2 is better for a good flush.
After all this growing, we are going to want to see some hash shots too
