going to the right dispensary i find the bud is going to be stronger. i assume they are growing under stronger lights than most home growers are going to care to use, so i think that and the fertalizing mostly contribute to when the buds get really strong and over 30%thc.
i did a pretty good job fertalizing from what i read at the time and was using a 400watt hps light. i tried seeds from a few different places. a lot of them had good reviews, but none of the indoor weed that i grew really got me baked like i like.. i grew some outdoors where i could smoke a few bowls and it would do the trick, but i never got good indoors.
with that being said, i got some bud from the dispensary that was discount or shake a few times recently and it doesn't do the trick to get me baked. i hear more and more stuff about how thc percentages aren't even real on the internet recently, and i'm starting to wonder. a person on reddit was saying there are cannabinoids that are unknown so far... i have no idea... i find if i get a good brand, i stick to it. like i got some stuff that was 15% thc recently for pretty cheap and it's really good. another dispensary was selling the brand for real expensive, but another store had it for discount, so i figured i'd give it a go.... i've heard people on here say to go with the smell you like over the thc percentage. i have no idea at this point. mostly just stick to the brands that are good.
