Hey dude I just breezed thru this thread and you did really good work especially for your first grow.
One thing I think you were lacking is in the genetics department, think you had clones for your first run and just noticed the bud looked like boof, didn't have much trichome content..the buds looked like they had no bag appeal> don't take offense to what im saying because I honestly think you got some crappy genetics/clones given to you. I know that's not everything but I take you have to move that bud and I know the first run stuff you had, and even some of the others would sell for way under 1000/lb around me and that's if you could even move it- people around my way wouldn't even take subpar bud these days, there's just so many cheap packs of really good bud around now. The reality is if you're growing you have to be growing the best shit around these days to sell high end work.
Breezing thru this thread though I really don't think its your grow methods...you seem to have your grow pretty dialed in, you have a good understanding of environment and keeping in a proper vpd rang for different phases of flower- again I think you just had some crappy genetics especially the first few runs, stuff just looked super airy, and had no trichs. How were the terps and nose? The last few pages the bud looked a bit improved. Genetics are one of those things you don't want to cheap out, I've seen people get crap clones and were told they were all fire strains only for them to be shit and ruin their grows.
I think if you got some good cuts or killer genetics in seedform in your room, you'd do really well. I'd drop the ethos gear, his stuff is subpar. I have run ethos strains and think they lack potency, onky strain that was decent was the crescendo. If you had that room filled with say Gary payton or Grape Gasoline I'd bet you'd pull some absolute fire. Dm me if you need some recommendations. Please dont take offense to waht i said- you're a good grower most people would've have failed doing a grow your size for their first run but you did great, now I would love to see you run some top teir genetics.
