So you are saying you don't need to use CO² it's a waste of time and money? You can just crank the temps and get the same results?

Sorry sticky but that is just simply wrong.

FACT: Carbon Dioxide Is Great for Plants

By Sylvan H. Wittwer - professor emeritus of horticulture at Michigan State University, directed the Michigan Agricultural Experiment Station for 20 years, and chaired the Board on Agriculture of the National Research Council. He is the author of the world's leading textbook on greenhouse vegetables, and is co-author, most recently, of Feeding a Billion: Frontiers in Chinese Agriculture.

??Flowers, trees, and food crops love carbon dioxide, and the more they get of it, the more they love it. Carbon dioxide is the basic raw material that plants use in photosynthesis to convert solar energy into food, fiber, and other forms of biomass. Voluminous scientific evidence shows that if CO2 were to rise above its current ambient level of 360 parts per million, most plants would grow faster and larger because of more efficient photosynthesis and a reduction in water loss. There would also be many other benefits for plants, among them greater resistance to temperature extremes and other forms of stress, better growth at low light intensities, improved root/top ratios, less injury from air pollutants, and more nutrients in the soil as a result of more extensive nitrogen fixation?.

??Most plants includes this great plant too"

There is no way in HELL that I could have ever grown KBS with out CO².

You are correct that it will only really do you good if all the other environment factors are in harmony. CO² is a booster for the plant just like fat flower, madd-farmer, and the other flower boosters. You can grow with out them yes but you yield is not as high and your finish time is longer.


This FACT has been proven over and over again on this forum and just about every single book written on plant botany about the benefits of enhanced CO².


Sorry to strongly disagree with you sticky but that??s my job to keep the facts straight.

That was the original question asked ??does co2 speed up flowering time??
