I am so happy with this grow. Everything is just fabulous. The plant is growing beautifully. I buckled down and started a little LST after all. There's not much room for it due to the small pot, and I'm just bending the lower branches a bit to the side so it doesn't all grow upwards. A growmie here has given me lots of lovely air pots - next time I'll go one size bigger. Thanks again, Mia!
I removed two big fan leaves in the upper area that were hogging all the light for themselves.
This week, as always, tap water and a little Bactrex.
In the meantime, I've finally installed a decent humidity and temperature meter. Partly because I had no exhaust air, partly because it hurts a bit more when three plants go moldy than when just one does. It's fun to monitor that. At the moment it fluctuates quite a bit because I occasionally have the box open for longer, but that will normalize. My exhaust air set is the one from the old grow box and is a bit too small and, above all, too loud. But it's good enough for now.
