Damn that’s a lot of pens wood, i use verm and perlite not coco, how do you feel about those blue lab pens you got there.. my local hydro guy runs with something like that but when I went to the shop for a new pen since mine was off he brought his out and it turned out both were off a bit. Even though I blame the blue lab solution that we used, maybe the wife left it out in the sun or something..
