Most plants will benefit a lot if the amount of carbon dioxide in the air around them is increased by 3 to 5 times. For example, up to 30-40% increases in yields of fruits and vegetables in greenhouses have been obtained by increasing the CO2 concentration.This book aims to save you time and money by looking at how to introduce CO2 into your growing room, how to avoid wasting it (for example by having a leaky room or inadequate ventilation), and how to add it at the right times to get the best plant growth.Paperback. 198 pages.
