man... all I had for information back in the day was an illicit book on illegal drugs, circa 1970s, it was so old it referred to the "new" type of marijuana.... sinsemilla...
I didn't have a "good" grow for the first 5-6 runs, over the course of 4-5- yrs, I was around 17 when I had my first good run, grown with a non-remote, magnetic 400w mh ballast, the damn lamp literally weighed 50 lbs, hung that sumbitch from my closet rafter, hole-sawed a hole in the ceiling (carefully keeping the part that was cut out... I was renting) for the "bathroom" fan to pull the air .. that thing put out some HEAT..
FINALLY grew some worthwhile herb though.. northern lights #5, skunk #1, and some good bagseed.
-note- I doubt either of those were the REAL nl#5 or skunk #1... but it was GREAT shit compared to the brick, and 60 dollar, 3 gram "eighths"
Point is, you are WAY ahead of where I was, so don't beat yourself up man, you are doing great, I've seen your pics
