GB Original XXL : coco/soil mix

recently, when I bought my Advanced Nutrients coco nutrients from Growbarato, a little surprise came with the package: 5 seeds of their Original GB XXL auto. nice 👍 My tents are currently in the early stages of 42FB Gorilla Punch sessions, and I have beefed up my equipment with two quantum board LEDs, 97W and 142W. So I'm left with my "old lamps", which I don't really want to throw away... I also still have my first tent, a 40*40*140, cute... and above all I have a 70*70*100 hole in my cellar, which with a little DIY I could turn into a secret underground garden... it's done 👌 ; I now have 3 small Original GB that are coming out of the ground, in 7L coco/soil pots, that I'm going to LST or top to keep their size under 50cm. It will be Rhizobacter for the grow and Terra Bloom afterwards; objective: 50 to 75g together, we'll see ✋
