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

Air conditioning: Plants are looking great. It is still a bit too hot for my taste when the lights are on. The A/C unit should be arriving some time soon. I hope to be able to control the temperature better then. The Ecoflow Wave 2 airconditioning unit has arrived, however I need to find some time next week to install it. It is quite large and heavy and tricky to find a place within the grow box. Installed the Ecoflow Wave 2 A/C. It is a bit cramped now. The Church: Week 2 for The Church is going great, they are looking healthy and grow steadily. They have reached heights of 12-15cm. Planning to top them soon to get them ready for ScrOG. Day 13: Started with topping on the largest of the four "Churches" beyond node 4. Serious 6: Week 1 in Autopots has begun.

The tips of the fresh leaves are also starting to grow yellow. I lined the hole with 5g of Mycotrex before repotting the plants. Seems like the issue was dryness. I should have kept the substrate hydrated from the top instead of relying on the autopots in the early stages of the plants. The fresh leaves
