I knew going in that this handbook was for commercial growers so though I hesitated at the price I thought it would be worth it because it would be so complete. Boy, was I mistaken. I can't believe this is what professional growers use. The information is so hit and miss.I guess the biggest problem is the inconsistency about which vegetables and crops are covered. In some places they list every vegetable you can think of and in others they list fewer than 15. Need to know what temperature to ship vegetables or how much a crate of yucca weighs? There are pages and pages devoted to it. Need to know germination temperature for seeds? There is less than a page and exactly 12 vegetables listed.I think most growers [even commercial ones] would be better off searching out the information they need for the specific crops they plan to grow. In fact, much of this book is dedicated to listing websites and government agencies rather than including the information.
