Here we are! More about germination method below.
Planted at night from Saturday to Sunday, after 48 hours the girls showed themselves on Tuesday morning. Monday I already tried to make it a little easier for them by sprinkling some water on them and moving the substrate a little bit to the sides. They were too shy to show themselves though and I turned the lights and the exhaust fan off, letting them enjoy the darkness, silence and humidity. Tuesday morning the two more confident ladies showed themselves. I knew their sisters can't be so far away! Again I sprinkled some water on them and voila! Here they were, looking excited, almost happy I helped them reach the nurishing rays of my self built Led chandelier! I hope you'll have a wonderful, short but productive life.
About the germination method. After filling the pots tightly with substrate, I flush them completely so everything settles and I'll get an even surface. There I gently lay the seed on the top, just press it on a little bit, don't push it in. Then I'll get some more wet substrate and put one complete 1 cm layer on top. The seed is now locked in place and you have complete control over how deep you want it to be. I learned this technique from German YouTuber "guerilla growing". Hasn't failed me a single time so far!
I'm new with perlite though and maybe I put about 10% more than I would've liked to. More drainage I guess. I sprinkled some water on the seeds about 3 times a day to make sure it stays nice and moist.
