Greenhouse and forced greenhouse climate control system and method

A method for controlling the temperature within a greenhouse growing section, comprising:

• flowing air through one or more vents into a climate control system from outside said greenhouse, from inside said growing section, or a combination thereof depending on the temperature needs of said growing section;
• conditioning the air by controlling its temperature and/or pressure and/or the level of certain gases contained within the air, as it flows through said climate control system;
• flowing conditioned air through a plurality of tubes into said growing section to regulate the temperature in said growing section;
• and
• re-circulating air within said growing section when the temperature therein is at the desired level by flowing the air back into said climate control system, then flowing the air through said plurality of tubes into said growing section.
