Having the same time to grow, seedling, cultivated with the use of AgroLED-II-100W (TOP) lamp, has higher quality comparing to the HPS grown. While electricity consumption decreased by 6 times.
Seedlings for transplanting are the same in both options. All the cubes are nourished with nutrient solution before transplanting. ЕС- 2,2 mS/cm; рН - 5,3-5,5; supplementary lighting is 24 hrs a day, for 3 days; air temperature is +23 °С.
On the 7th day after transplant both samples already have their “true” leaf. Supplementary lighting is 18 hrs a day. The first watering was after 5 days with a nutrient solution ЕС-2,4; рН-5,5 + "Previcur-0,1%", air temperature: day +22 °С, night +19 °С.
On the 10th day after transplant, cucumber seedlings have large first true leaf, as well the formation of a second one. Seedlings were distributed over the area. Supplementary lighting is 18 hrs a day. Watering is carried out as the cubes dry out (weight loss 25%) with a nutrient solution ЕС-2,4; рН-5,5, air temperature: day +22°С, night +19°С.
Seedlings of both samples are actively growing, the next leaf is formed. Seedlings are prepared for planting in a permanent location. Supplementary lighting is 16 hrs a day. Air temperature: day +23°С, night +19°С. Cube measurement before seedling planting: ЕС-3,0-3,2; рН-6,0-6,5
