The book is very well presented, the typography is clear and the illustrations good. Unfortunately it is let down by poor editing, with many sentences repeated.
I bought the book hoping to figure out how to grow tomatoes hydroponically in a green house and although I have learned a fair bit about hydroponics, I still don't have the knowledge to do this. If you want to grow "high energy plants" in a stealthy grow room somewhere in your house, this is the book for you. Otherwise, it is rather too limited in aims to be of universal use.
