Personally, I like having something in my hand to reference when I'm encountering a problem and my rooms location makes it pretty much dead to any cell/wifi signal. Also, I have a LITTLE more faith in someone who managed to get a book published on a specific subject than a bunch of random people from the interweb..I've been on this forum long enough to know that better than half the people on here don't know the first thing about growing plants in general, never mind the specifics of MJ. The forums are great places to find information, but if someone wants to be spoon fed rather than take the time to read as much as possible regarding the issue and extrapolate what is true and what is bunk it's not going to help much...too much biased opinions instead of fact..
To the OP..the only way to become advanced at anything is through experience..
