The GSC is a 63 to 70 day pheno I love seeing big plants it makes me feel like I am good at this growing stuff. I've made plenty of mistakes in the last 6 years of growin. I used to grow in soil and had a heck of a time with over watering plants never got real big. Since I switched to COCO things changed can't over water and all I feed is Canna A&B nutrients with some silicon and 4 weeks into flower I add some PK 13/14 for a couple weeks and then it's just Canna A&B and silicon the rest of the way.
