First Grow - Triple Automatic: Purple Haze, Apple Fritter, Purple CousKush

Alright, here we go! First ever grow, absolutely no experience, could not manage to keep succulents or cacti alive in the past so let's see how this works. I did read alot and watched youtube videos, hope it helps. I'm growing in my cellar where it is a stable 16-17° with 56% humidity. I will find out if the LED inside the growbox is enough to keep the temperature above 20°C, else I will turn on an additional electrical heating. I threw the seeds for 24h in a waterglass, then in jiffys with a heating mat under them, set to 23°C (73,4°F). I have also attached my rough plan / cheat sheet.
