They vegged almost 2 months before flower, but the first 6 weeks they were under a shop flouros and in tiny cups to keep them slow growing. 2 weeks under the 1000 MH before setting to flower (2 per 5 gallon bucket in organic soil mix). The stretched for a good 8 weeks or so and estimate 400-500% stretch during that time. The tallest is still stretching though! They have been fed nothing except what was in the mix as sat doms tend to be lite feeders and burn easy.
Will see on yields, generally I find sativas from seed do not yield as much as from clone and overall sativas produce lots of bud but it rarely weighs out like a commercial cropper. But NH has never really been a commercial cropper unless you luck out and find a fast flowerer. Even then I suspect the most trippy phenos are almost always head stash and rarely make it to commercial settings because the time/effort/yield is too great compared to say ye old chems, etc (which I find to be very strong but pretty one dimensional even if a cash croppers dream).
Like probably many NH growers the interest is in the trippy phenos which are rarer, but I always do very much dig a euphoric/spiritual plant which I find much more commonly in sativa haze doms.
I had some NH in the Dampkring in Amsterdam once. I kept thinking "this is pretty great but I am sure this could be even better".
I later found out that it was from a grower that was also active on online boards and soaked up a lot of stuff there apparently, so I was told several times that the Dampkring NH is "as good as it gets".
But I would wholeheartedly agree with you sysadmin: It is probably "as good as it gets COMMERCIALLY". I bet there are better phenos in NH that just don't yield enough or take too long to finish and thus are discarded for commercial production.
Haven't popped any of my NH yet but am sitting on about 40 of those and will probably come around to it next year. I have my fingers crossed for a pheno that isn't commercially viable but provides "dat trip haze".
But I can say that even the commercially viable NH from the Dampkring, definitely put you in that "hazy state". I like to compare it to the winter, when fresh snow just fell. Everything sounds and feels a bit different, softer, kinder. Like everything is "dampened", moves slower etc.
It was a very kind and very nice effect, it really put you in a "hazey state of mind".
Wish you best of luck in finding something like that too!
