Changed water in the res at the beginning of the week. I have a 50w aquarium heater in each tank which keep the water temps at a consistent 20c. Roots are looking nice and healthy and no sign of any burn. Not done this strain before and not a lot online about her so just taking it easy with the feed. They seem to be coming on really well. There’s one at the back which I think could turn into a bit of a monster. Looking forward to start seeing some flowers on her.
