Growing again after 13y

Luigi_13IE Day -1: 1) Preparing the soil to sterilize, horticultural sand and perlite, DIY compost from veggie scrap (1y old), old soil (got from free in the woods + old compost + some top soil I bought) 2) Hot water to sterilize pot and soil. 3 & 4) My mascot is Stormy, she is inspecting my biochar. I charred some wood in a open fire, then close it to reduce oxygen to get some charcoal. The charcoal was then inoculated with NPK+Mg fertilizer, rice with white mold, and seaweed compost. Biochar do not need sterilization with hot water or it will defeat the porpoise. 5) Once soil was cold, i mix it with the biochar and put in the pot. 6, 7 & 8) Placed the pot in the smart pot4pot (provisory name). Being an electronic engineer helps with gardening too, this pot was build to regulate the temperature and help with the irrigation, unfortunately the soil humidity sensor broke but temperature regulation works fine. Set to maintain the temperature in the 24 to 26 range, use a wire heater bellow the pot and a DS3231 temperature sensor with fancy 20V power supply. 9) Seeds in the chamomile and cinnamon tea. This should reduce the fungi infection of the seeds. Unfortunately, 2 seeds were fat and dark, 2 smaller and light color. I pick one of the fat and one of the small one. Day 1: 10) Placed the seeds on top of the soil after 8h of bath in the tea. Covered with cotton for 12h then covered with soil. Day 4 : 11) Fat seeds sprout overnight. Day 7: 12) The plant is growing well, exposed to a south south-est windows receive 80% of the total day light but it looks like is elongating. No sign of life yet from small seed.
