Thai Herer 99 (F) Photoperiod, First Grow

Seeds sowed directly to moist Purple Cow Seed Starter Mix on August 20, 2024, at 2:30 UTC and all four cups labeled and placed in AC Infinity Propagation Kit. Photon flux at between 200-300 umol/m2/s, typically around 300. Temperatures maintained around 29c and humidity around 90%. I aimed to keep VPD low around 0.4-0.5 kPa but not going crazy trying to maintain it perfectly. Around 4 times a day I would remove the humidity dome to refresh all air in the kit, then mist the soil a little and put the dome back on. August 22, 2024, at 5:00 PM UTC: Tent is fully ready and passing VPD control smoke testing, so I moved the propagation tray into the tent, suspended on a wire shelving unit by 4 YoYo cables. The exhaust fan is set on a cycle of 1 minute runtime at 50% power every 45 minutes to cycle fresh air. The photoperiod is 18 hours. The photon dosage is at 285 umol/m2/s as measured with Photone. Floor to light distance is 147cm. Distance from the soil surface to the light is 67cm. The light is powered at 20%. Oscillation fans are at 30%. Humidifier is targeting a VPD set point of 0.6, with the goal of keeping VPD around 0.5-0.6 during germination, as temperature fluctuates with the photoperiod. 8 hours later, there were no signs of germination. 12 hours after moving to the tent, #2 and #3 have successfully emerged from the soil. #2 shows open cotyledons and a visible true leaf. #3 has not yet opened its cotyledons and no true leaves are visible yet. #1 and #4 are yet to show signs of life. I'm hoping they emerge today. I will update the success count and photos as germination progresses. CO2 concentration during these days so far has been between 1000-1300ppm.
