Howdy gang! Been experimenting with Grodan cubes a bit and liking the results so far. I usually grow in coco. Found a good video from Jungle Boys about their grow SOPs, and Ivan was very adamant about 5.7 being the magic pH for rockwool. Found some basic info on grodan101.com as well. If you are a rockwool fan, do you have any tips to offer? Things to never do, things to always do, etc. So far so good, big big fan leaves, some big chunky buds too, but my knowledge is very shallow so far. I feel like maybe I have been getting lucky.
