===== (12/17/23 07:06 PM) ===== 1. Seedling is moved onto DWC system running 0.01% H2O2-treated seedling strength nutrient solution @ 340 PPM, PH 5.9. 2. Seedling is supplied with 140 µmol/m2/s of light from the main grow light under 24/0 schedule (DLI: 12.1 mol). 3. Climate is recorded at 22.2 degrees Celsius, 75% RH, 1555 PPM Co2. ===== 28 HOURS LATER (12/18/23 10:51 PM) ===== 4. Nutrient parameter is recorded at 370 PPM, pH 5.8. 5. Climate is recorded at 23.1 degrees Celsius, 66% RH, 1520 PPM CO2. ===== 25 HOURS LATER (12/19/23 11:39 PM) ===== 6. Nutrient parameter is recorded at 370 PPM, pH 5.8. 7. Climate is recorded at 23 degrees Celsius, 68% RH, 1425 PPM CO2. 8. Leaf temp: 21 degrees Celsius, VPD 0.58 kPa. 9. Light intensity is increased to 190 µmol/m2/s (DLI: 16.42 mol). Light height 19.5 inches. 10. Co2 intensity is increased to 550 PPM. ===== 21 HOURS LATER (12/20/23 09:00 PM) ===== 11. Nutrient parameter is recorded at 360 PPM, pH 6.1. 12. Climate is recorded at 24 degrees Celsius, 63% RH, 870 PPM CO2. 13. Leaf temp: 22 degrees Celsius, VPD 0.82 kPa. ===== 39 HOURS LATER (12/22/23 12:45 PM) ===== 14. Nutrient parameter is recorded at 370 PPM, pH 5.6. 15. Climate is recorded at 25 degrees Celsius, 73% RH, 1135 PPM CO2. 16. Leaf temp: 22.5 degrees Celsius, VPD 0.54 kPa. 17. Co2 intensity is increased to 600 PPM. 18. Leaf symptom observed. Probably because humidity too low and the root does not reach water line yet / humidifier ran out of water for around 4 hours during 05:00 - 09:00 AM. ===== 11 HOURS LATER (12/22/23 11:20 PM) ===== 19. Leaf temp: 22 degrees Celsius, VPD 0.48 kPa. 20. Climate is recorded at 25 degrees Celsius, 70% RH, 1055 PPM CO2. 21. Nutrient parameter is recorded at 370 PPM, pH 6.0.
