| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Growing Environments: A fully automated greenhouse and a quonset equipped with heater and limited cooling capacity. Containers: Seed sown into ITML brand 128 cell plug trays. Plugs transplanted into T.&O. Plastics brand SVD 2 1/2 inch containers. Media: Seed sown into Fafard Super Fine Germinating Mix. Plugs transplanted into Sunshine SB300 Universal bark mix. |
||
| Establishment Phase: | Sow date was late July. Seeds were hand sown 5 to 7 seeds per cell to produce a clump. Seed was not covered because light aids in germination. Flats were grown for 12 weeks in a shaded greenhouse under an automated mist system set at 3 seconds of mist every 30 minutes. Air temperature was set at 65 F and bottom heat was run at 60 F. Flats were moved to a shaded quonset for 16 weeks. Temperatures were kept as close to 38 F as possible but not allowed to go below freezing. Flats were then moved back to initial greenhouse until germination. After germination, flats were moved to a fully automated greenhouse. Temperatures were set at 68 F days and 64 F nights. Day length was extended to 12 hours using HID lights. Seedlings were hand watered when dry and fertilized weekly with 20-2-20 fertilizer at 200 ppm. | ||
| Length of Establishment Phase: | 33 weeks | ||
| Active Growth Phase: | Plugs were transplanted when firmly rooted in mid March. Plants were grown in a fully automated greenhouse where temperatures were set at 65 F days and 61 F nights. Day length was extended to 12 hours using HID lights. Plants were hand watered when dry and fertilized weekly with 20-10-20 fertilizer at 237 ppm. | ||
| Length of Active Growth Phase: | 8 weeks | ||
| Hardening Phase: | Plants were moved outdoors to a cold frame in late May. | ||
| Length of Hardening Phase: | 2 weeks | ||
