So yes there is, like I said, a whole pile of info, some good, some bad. Where would you suggest a person go to learn if they had no clue where to start? As for pulling leaves my experience is don’t unless you fucked up and over filled. I’ve never seen it help any of my grows but perhaps some others have success. That’s why I advocate trying different methods. It’s a plant FFS, have fun with it lol.
If you really wanted to learn you would complete basic college sciences and maths then enrol in either a farming college or hi-tech agriculture and lab study if you want a deeper understanding.
Most who do that won't be needing these type of site and are already proficient enough,. There's bigger and better paid opportunity out there than this, some cannabis companies may even have employed some to do the more complex work a grower could not do without help.
A good grounding in lots of species and ways of growing is another way, been gardening long? You probably can appreciate the simple side and do well with cannabis indoors.
Without this you end up here chucking a $1000 at the latest led because other lights only fry plants, you add strong acids and alkalis to soil which dosent want or need it and creates big imbalance, you grow a plant then strip 70percent of leaves of it in the belief less is more and then stick your damp bud in a jar with drying aids then claim the wrong humidity caused the cure to stop and it all turn to low grade bush weed.
I'm not saying some won't avoid that or eventually learn it's just I don't need to hear their opinions until they hit a certain level of competence.
I don't defoliate because I produce more without, by the time my plants start flowering they are the size and shape I want not overgrown by 70percent and needing stopping back, if I want to add a few weeks to veg and get less yeild and harvest I can defoliate which I know all about. If you have enough light in the field you never cut back, only crop this benefits are ones where less energy into fruiting and flowering makes a superior product at the expense of less yeild.
Some answers seem too simple but here it's an endless debate, I feel sorry for soil growers being tricked into buying the whole pH kit when they didn't ever need it, weed sites are like this other places are not and leave you with a proper education you can transfer to most other types of growing.
