Adding Biology - For Soil and Hydroponic Systems Paperback – January 1, 2008

This book has taken my straight chemical nutrient approach of hydroponics to a new level. The use of worm casting teas has allowed my nutrients to be effective over a wider range of concentration and pH. A huge step at getting 'back to nature' with hydroponics. I would recommend this highly.

I love this book. i conjunction with a few others this is hands down a have to have for your library if your an organic and/or natural gardener/grower.

An AMAZING BOOK...Dr.Ingham is a total ROCK STAR -bringing the knowledge of Soil Food Webto the public!
