Thermoformed double tray system for cultivation of plants including a top tray which is stacked with a bottom tray. The top tray has cells for receiving a substrate. The bottom tray provides rigidity to the double tray system. The bottom tray has a baseplate which is provided with support elements to support the top tray. The baseplate has an outer edge which defines the outer contour of the bottom tray. A groove shaped deepening in the baseplate is extending in parallel with the outer edge. The deepening increases a bending stiffness of the bottom tray and provides rigidity to the double tray system. The deepening is provided with a reinforcing ribs which cross the deepening.

1. A double tray system for cultivation of plants comprising: a top tray including a plurality of cells for receiving a substrate, wherein each cell includes a cell space which is defined by a circumferential cell wall and a cell bottom; anda bottom tray for supporting the top tray, the bottom tray including a baseplate, wherein the baseplate comprises: a bottomside;a topside;a plurality of supporting elements for supporting the top tray, said supporting elements project at the topside away from the baseplate, wherein the baseplate has an outer contour which is delimited by an outer edge; anda groove shaped deepening which is open at the bottomside of the baseplate, said groove shaped deepening protrudes at the topside away from the baseplate, said groove shaped deepening is elongated and extends in a longitudinal direction in parallel with the outer edge of the baseplate,wherein the groove shaped deepening includes a plurality of ribs formed on the bottomside of the baseplate, the ribs and the supporting elements separating the groove shaped deepening into a plurality of groove shaped pockets and each rib extends in a direction transverse the longitudinal direction of the respective groove shaped pocket,wherein the ribs are positioned external from the supporting elements,wherein each groove shaped pocket is positioned adjacent to at least one of the plurality of supporting elements,wherein each rib is positioned between a pair of neighboring supporting elements of said plurality of supporting elements, andwherein the outer edge surrounds and is spaced from the groove shaped deepening. 2. The double tray system according to claim 1, wherein each groove shaped pocket has a rounded bottom surface. 3. The double tray system according to claim 1, wherein each groove shaped pocket has a closed bottom surface. 4. The double tray system according to claim 1, wherein at least one rib of said ribs is formed by an expanding step of a thermoforming process by expanding the pockets, while leaving at the same time a portion of the baseplate unexpanded. 5. The double tray system according to claim 1, wherein the baseplate of the bottom tray comprises an outer flange which is curved with respect to a horizontal plane defined by the baseplate. 6. The double tray system according to claim 5, wherein the bottom tray comprises a support rim for supporting the bottom tray to a supporting surface, and wherein the support rim extends in parallel with the outer edge and is positioned in-between the groove shaped deepening and the outer flange. 7. The double tray system according to claim 1, wherein the groove shaped pockets with support elements of said plurality of support elements located at an outer region of the bottom tray. 8. The double tray system according to claim 7, wherein the support elements which are positioned at the outer region of the bottom tray comprise an extension in a sideward direction for supporting a cell wall of a cell of a top tray. 9. The double tray system according to claim 1, wherein the top tray comprises a flange at an outer circumference, wherein the flange extends away from a horizontal plane defined by the topside of the top tray. 10. The double tray system according to claim 1, wherein the double tray system is a thermoformed double tray system. 11. A bottom tray for a double tray comprising: a baseplate including: a bottomside;a topside;a plurality of supporting elements for supporting a top tray, said supporting elements project at the topside away from the baseplate, wherein the baseplate has an outer contour which is delimited by an outer edge; anda groove shaped deepening which is open at the bottomside of the baseplate, said groove shaped deepening protrudes at the topside away from the baseplate, said groove shaped deepening is elongated and extends in a longitudinal direction in parallel with the outer edge of the baseplate,wherein the groove shaped deepening includes a plurality of ribs formed on the bottomside of the baseplate, the ribs and the supporting elements separating the groove shaped deepening into a plurality of groove shaped pockets and each rib extends in a direction transverse the longitudinal direction of the respective groove shaped pocket,wherein the ribs are positioned external from the supporting elements,wherein each groove shaped pocket is positioned adjacent to at least one of the plurality of supporting elements,wherein each rib is positioned between a pair of neighboring supporting elements of said plurality of supporting elements, andwherein the outer edge surrounds and is spaced from the groove shaped deepening. 12. The double tray system according to claim 1, wherein each support element of the plurality of support elements has a base surface having a substantially square pyramid shape and a top surface having a truncated shaped. 13. The bottom tray according to claim 11, wherein each support element of the plurality of support elements has a base surface having a substantially square pyramid shape and a top surface having a truncated shaped. 14. The double tray system according to claim 12, wherein support elements of said plurality of support elements located at the corners of the bottom tray include two extensions, one of the extensions extending towards different side surface of the outer edge of the bottom tray than the other of said the extensions. 15. The bottom tray according to claim 13, wherein support elements of said plurality of support elements located at the corners of the bottom tray include two extensions, one of the extensions extending towards different side surface of the outer edge of the bottom tray than the other of said the extensions.
