This thread sure grew quickly. It took me quite a while to catch up. It's good to see so much interest. I agree with most of the basic ideas. It seems one of the main difficulties is managing complexities.
I've traveled down a similar path in terms of creating documentation. I have been writing about my growing methods for about two years. I have a complete outline that's nevertheless still a work in progress. I have also been collecting research and done a lot of writing. That includes taking things I've written on forums and saving them for future use. I've found that correcting my own errors and misunderstandings can be difficult and time consuming.
At this point, I imagine I could easily spend as much time as I've already spent and probably much, much more. Whoever wrote about thinking at the start that growing would be easy described my circumstances perfectly. Even if I confine my documentation to my own style of growing, it may never be completed.
I do like the idea of a forum for either tutorials or maybe start-to-finish methods that are known to be successful. That's the key concept, I believe. Basically, simplify the process of how to grow good weed, each written for a specific growing style. Having followed a plan that's known to work, the new grower can then proceed to future growing with the confidence that comes from a positive experience. Thus, the task at hand is to provide a solid foundation from which anyone could apply and increase their own talents.
