The Medical Cannabis Guidebook
The 220 pages of this book are so densely packed with information and I know I'll want to keep it handy as a valued reference book.
Amongst many other things they show you how to make various extracts and how to grow enough cannabis in a 4 x 4 grow tent to medicate for any condition.
