Just post in the growing section and wait for one of the guys with some rep to respond. I find that the growing section overall tends to have a lot better advice and a lot less stupidity then the rest of the site.
Besides the same would happen, just like seasoned tokers you would get noobs thinking there awesome and a seasoned grower, therefore you would get tone os bull shit information. And it just wouldn't work.
No, but if you're a grow expert you will tend to get a lot of rep, plus people with a lot of rep tend to give good advice.
