Wanna see Northern Lights [Hydro/Soil-hybrid]

Topped on D27. Moved into a DIY spaceblanket/cardboard growbox for better climate and light. Got an easy +1.5°C and +5%rh on average through this simple build. No fans, box always open on one side. The box also sits on top of a 40cm subwoofer that runs the bassiest stoner rock 👽 and and even fuzzier doom metal 😈 for an average of 4hours a day to please my ears 😑 and vibrate those roots 😵 Also did a lot of testing with an Apera pH60 this week and put a lot of the nutrients+tapwater+citric acid solution into the reservoir and a bit on the soil. Also I now know how much citric acid I need to bring the pH of my tapwater to 6.5, more than I previously used as my tapwater starts out at 7.5
