I agree that learning from experts, ie... botanists and the lot, can't hurt.
You learned more in 3 days than 15+ years of growing? Leaving yourself WIDE open aren't you? Sorry,
Yes I did leave myself wide open with that statement, but it is true. Yes you learn alot from other growers and from books, but still have no real knowledge on why or how it really helps. These courses give you that knowledge.
The KISS method works great for average consistant results. A little knowledge and modern help(actually it is really simple once you understand how it works) will produce crazy good weed with better yields.
Yes the method I described is for a micro/closet grow with a area of 4sq. ft. to easily 100 sq. ft. as temp controls yield and quality more than most know.
