Oh, these look cool, too. Maybe I am going to build one of those.

I would like to, but sadly my current setup does not allow me to use vegetative and flowering light schedules in parallel.Though, there are relatively cheap plant propagation kits with built-in light and heat sources, might get one of those anyway in future.

I repotted it earlier and as far as I can tell, roots have grown to a reasonable size and had a healthy, white color.
