First grow diy automated 4x4 closet

Starting veg, the first 2 seedlings streched alot, but we are planning on only potting 9 out of 12 to the bigger pots so if they dont make it it wont be the worst. We are keeping temps between 20 and 25 °C with humidity between 55 and 65 RH% we have put some mycorrhiza at the roots and gave them some bacto with the first watering. Lamps are currently at about 50% so about 280watts Any tips are always welcome
