IKEA Stealth Grow // The Church, Serious 6, with mobile A/C unit on 1,2 square meters

Ventilation, Temperature & Humidity: I got my monoblock A/C unit more or less figured out. Had to play around with the settings and adjustments. It is not directly made for this job and needs close monitoring. But finally I got the high temperatures in check. Also, it got colder outside, which helped. My RH is still quite low at around 30-40%. Probably will rise with more leaves coming. The plants are starting to smell a little bit. With my new A/C unit, some of the air blowing out is not going through the designated air filter and vents, but through the A/C unit unfiltered. Perhaps I need to power up my vent with the filter up to create negative pressure. However, that might suck out the cool air, since the A/C is located almost next to the filter. Need to play around more, perhaps attach another tube to direct the cool air to the bottom. The Church: Topped The Church during the end of week 2 and beginning of week 3 to get them ready for the ScrOG. This week I am going to start weaving them into a screed grid, which I am using to scrog. Serious 6: Thanks to your help they are recovering. The problem was a dry substrate at the very top. I thought that I had watered it sufficiently further down where I placed them, but the top layer was too dry. As soon as I got it moist, the plants rushed to produce new very green leaves.
