Greenhouse auto grow

So now it's my third grow. This year I have decided to grow auto plants, because of last years harvest was ruined by mold. Here in scandinavia the flowering season is so late so photoperiod plants start to flower in september and by then the humidity was too high. Anyways i have three different strains. Crystal meth and pineapple express are grown in 25 l pots. The big bang auto is grown in a capilary case, which is a self-watering system. This year im using biotabs starterkit. All my plants are in a greenhouse. I made a stupid mistake by forgetting which pot is crystal meth and which is pineapple express. Hopefully I can tell them aparte by some point.... Any help would be appreciated. Hope you enjoy!
