Thanks for the tips. They do not have to be grow books. I think I have a solid grow book now with The Cannabis Grow Bible. What I want to know is how well the other books have been put together. I am not looking for something that looks like it was put together just to fill some High Times back pages advert. I read the version of Marijuana Botany on the internet and was just wondering if anyone had the printed version. I have seen some scans of Hashish and that looks good also.
