A horticulture tray (402, 502, 602) comprising: a growing cell (406, 506, 606) including: a first end (412, 512, 612) defining a first aperture (420, 520, 620); a second end opposite to the first end; and a sidewall (424, 624) defining a plurality of arcuate shaped chambers that extend longitudinally between the first and second ends, each arcuate shaped chamber defining a plant supporting portion (456, 656) proximate to and spaced apart from the second end, each arcuate shaped chamber continuously tapering from the first end to the plant supporting portion, the plant supporting portion configured to support a perimeter of a stabilized growth plug received in the growing cell; wherein the second end comprises a supporting peak, the supporting peak configured to support the stabilized growth plug spaced apart from the second end; and wherein the sidewall (424, 624) continuously tapers over a first length from the first end to the plant supporting portion (456, 656) at a first rate and continuously tapers over a second length from the plant supporting portion to the second end at a second rate that is greater than the first rate, wherein the arcuate chambers cooperate to define the plant supporting portion (456, 656) at the junction of the first and second lengths (444, 448), characterized in that the plant supporting portion is spaced apart from the second end by a first distance and the supporting peak is spaced apart from the second end a second distance that is greater than the first distance. a growing cell (406, 506, 606) including: a first end (412, 512, 612) defining a first aperture (420, 520, 620); a second end opposite to the first end; and a sidewall (424, 624) defining a plurality of arcuate shaped chambers that extend longitudinally between the first and second ends, each arcuate shaped chamber defining a plant supporting portion (456, 656) proximate to and spaced apart from the second end, each arcuate shaped chamber continuously tapering from the first end to the plant supporting portion, the plant supporting portion configured to support a perimeter of a stabilized growth plug received in the growing cell; a first end (412, 512, 612) defining a first aperture (420, 520, 620); a second end opposite to the first end; and a sidewall (424, 624) defining a plurality of arcuate shaped chambers that extend longitudinally between the first and second ends, each arcuate shaped chamber defining a plant supporting portion (456, 656) proximate to and spaced apart from the second end, each arcuate shaped chamber continuously tapering from the first end to the plant supporting portion, the plant supporting portion configured to support a perimeter of a stabilized growth plug received in the growing cell; wherein the second end comprises a supporting peak, the supporting peak configured to support the stabilized growth plug spaced apart from the second end; and wherein the sidewall (424, 624) continuously tapers over a first length from the first end to the plant supporting portion (456, 656) at a first rate and continuously tapers over a second length from the plant supporting portion to the second end at a second rate that is greater than the first rate, wherein the arcuate chambers cooperate to define the plant supporting portion (456, 656) at the junction of the first and second lengths (444, 448), characterized in that the plant supporting portion is spaced apart from the second end by a first distance and the supporting peak is spaced apart from the second end a second distance that is greater than the first distance.
