5 weeks of flower. 1 400 hps. 2 gallon smart pots. ~50/50 coco/perlite with DynaGro Bloom and Pro-Tekt nutrients only.
4 plants (2 white widow, 2 pineapple express - both from G13 Labs). They are 36-42" tall each.
You did something wrong man.
P.S. Everyone fucks up as a newbie. I tried growing using shoplights and stolen HIDs from parks long ago using shwag seeds and never got anything more than a lanky hermie. This is my second grow in this setup and if you look at my first "real" harvest done "right"; well, the difference is night and day.
And the guy who says there is no "free" weed is right. Hell, labor alone can be a nightmare. I was up until dawn on my first harvest just trimming and hanging 2 plants. 8 hours straight! Not to mention the several hours a week or more that you have to dedicate (sometimes daily) to keeping them healthy and happy and your conditions optimal. It's a job, really.
