Its good right out of the bag for about 4 weeks. just water and cal mag at recommended specs. then you'll need to feed with your nutrient lineup after about a month. I re-amend with organic ferts and reuse, but it has compaction issues after a couple times and needs more coco/peat and perlite to fluff it up again. I've never really used any other soils because re-potting into roots saved my whole grow once, I was sold after that, but my buddy really likes happy frog and has very lush growth.
good luck, happy growin
