Help with soil coco

it compacts over time from watering. if you don't, use a normal watering can or wand to lessen impact of water compacting substrate - soil or coco. 10-20% perlite helpes too. unless you are transpanting, and likely even then, i would not disturb anything like what you ask. you will most definitely cause more damage than good, if any at all. roots can grow throug cement.. maybe not literally, but they are quite good at borrowing. it's okay. roots will air prune when they get to edges.. the solid nature will aid O2 at least to a larger surface, but the compaction never helps, but is unavoidable to some extent. It doesn't look like you just dump a gallon on your plants all at once, so all is well i bet.
