This small book has page long sections covering the basic cultivation parameters for dozens of home growable hallucinogens; from poppies to daturas, kava kava to morning glories, san pedro to syrina rue. The basic sections are Cultivation and Propagation, and Harvesting for each plant. The descriptions are useful, but not detailed enough to suffice as your only souce for growing anything. This is a book for collectors, but not for those interested in the information it contains. There’s better cultivation information available for most of these plants on the web.
