A greenhouse (10; 50), comprising: a growing section (16; 56); a climate control system (12; 52) within said greenhouse (10; 50), the greenhouse comprising a gabled end separated from said growing section (16; 56) by a partition (22; 62), the majority of said climate control system (12; 52) being housed within said gabled end with a portion of the said climate control system (12; 15) continuing into said growing section, said climate control system arranged to control the environment within said growing section by flowing ambient air from outside said greenhouse into said growing section, re-circulating air from said growing section back into said growing section, and a combination thereof, said ambient air, re-circulated air, or combination thereof, flowing through said climate control system (12; 52) and into said growing section (16; 56), wherein said climate control system comprisesa first vent (24; 64) running the length of an outside wall (26; 66) of said greenhouse, a second vent (34; 74) near the top of said partition allowing air from said growing section (16, 56) to pass into said climate control system (12, 52) for re-circulating back to said growing section and said portion of said climate control system continuing into said growing section comprises a plurality of tubes (18; 58), said first vent (24; 64) adapted to draw ambient air into said climate control system, whereby said plurality of tubes (18; 58) are in communication with said first vent (24; 64), said ambient air, recirculating air, or combination thereof flowing through said climate control system (12; 52) flowing into said plurality of tubes (18; 58), wherein each of said plurality of tubes (18; 58) has a means for allowing air to exit along its length, wherein said plurality of tubes (18; 58) are arranged at the bottom of said growing section (16; 56) to uniformly distribute air to a greenhouse crop within said growing section (16; 56) and wherein said partition (22; 62) extends along all of said gabled end with a gap for the second vent (34; 74). a growing section (16; 56); a climate control system (12; 52) within said greenhouse (10; 50), the greenhouse comprising a gabled end separated from said growing section (16; 56) by a partition (22; 62), the majority of said climate control system (12; 52) being housed within said gabled end with a portion of the said climate control system (12; 15) continuing into said growing section, said climate control system arranged to control the environment within said growing section by flowing ambient air from outside said greenhouse into said growing section, re-circulating air from said growing section back into said growing section, and a combination thereof, said ambient air, re-circulated air, or combination thereof, flowing through said climate control system (12; 52) and into said growing section (16; 56), wherein said climate control system comprisesa first vent (24; 64) running the length of an outside wall (26; 66) of said greenhouse, a second vent (34; 74) near the top of said partition allowing air from said growing section (16, 56) to pass into said climate control system (12, 52) for re-circulating back to said growing section and said portion of said climate control system continuing into said growing section comprises a plurality of tubes (18; 58), said first vent (24; 64) adapted to draw ambient air into said climate control system, whereby said plurality of tubes (18; 58) are in communication with said first vent (24; 64), said ambient air, recirculating air, or combination thereof flowing through said climate control system (12; 52) flowing into said plurality of tubes (18; 58), wherein each of said plurality of tubes (18; 58) has a means for allowing air to exit along its length, wherein said plurality of tubes (18; 58) are arranged at the bottom of said growing section (16; 56) to uniformly distribute air to a greenhouse crop within said growing section (16; 56) and wherein said partition (22; 62) extends along all of said gabled end with a gap for the second vent (34; 74).
