I totally agree! I've read the MMJ Growers Handbook numerous times and it contains enough information for anyone to grow. It's just laziness, anything in the that book can be found online for free.

Nothing like first hand experience though and learning through trial and error, doesn't matter how many times you read a book there is the potential for problems to persist that can't seem to be solved. If you're indoors and/or doing hydroponics then thats another whole different set of guidelines.

These sites are great for the variables you can't get from a book.
