I think the search function is over rated here, I always end up with pages of crap before anything useful can be found. Almost a waste of time. BUT there are some very good stickies:
From your initial posts it seems like you need basic info, read this
http://forum.grasscity.com/absolute-...row-guide.html
If you want to keep it simple and inexpensive, this is a Great guide for it
http://forum.grasscity.com/general-i...cfl-guide.html
this one has lots of visual info(charts). Thats always helped me understand things better
http://forum.grasscity.com/advanced-...rt-thread.html
Most of the sticky posts (at the top of the page) are full of very useful information, unless it's linked to overgrow which is usually a deadend now.
I'd say go check out the absolute beginners section for starters, then when you have a better idea of what your doing read up Dierwolfs guides.
