This has been a weird week, I woke up one day with a pot foam party due to a miscalculation of my new system which endangered my plant with a PH value of 2.8, 2.8 !!!
He changed everything and restored the solution. I had trouble with oxygenation so I changed my air pump to a brand new one (also very quiet) and put everything electric out of the growbox, now it looks cleaner!
