Royal Dwarf RQS - custom growbox - 1st grow

This is my first real grow. I tried once a few years ago, but with almost no equipment, so i consider that one as it never happened 😅 Now that I've updated my setup (and am still doing), what would be better then testing it in a fresh run. The box is made of thin pressed wooden panels and has a size of about 50 x 50 x 100 cm. It just took the seed about 3 days between two wet paper towels to germinate. After that it got directly planted to the final pot. She saw the sunlight for the first time on June 5 and the light was set to 20/4 at about 40% power.
