genetics is everything. you can grow in any medium, any mix of lights, fans, tent, and use any nutrients.. it ALL works. but what works for YOU, that is what you have to find out.
biggest and most dynamic change anyone could do is get a solid clone cut direct from a passionate breeder. not some hype strain, and dont pay hype prices. if they want more than a couple hundred, at the very most, I would rather dig threw seeds myself or find someone worth it.
vetting breeders is super hard, most just sell seeds with zero actual work put into their strains. honestly its a lot of these old school European breeders who have the literal worst genetics ever.
not trying to say who has better, but North America has amazing small and passionate breeders. Not the big ones,
check out BeLeaf, amazing work and some of his cuts are like 100. not bad.
its everything, literally. everything is just a detail.
hit me up if you want more info on better breeders, I would absolutely recommend White Clouds Genetics, the breeder Dan is doing great things
