hey there FistingNuns, you really do want to soak your cube, probably in a buffering solution or at least water. Usually you'll have your buffering solution also with a bit of nutrients. But the truth is that you really want to start feeding almost immediately , including with rooting agents . I use rockwool right now, but it's too keep a sterile environment, i really dont recommend it if you're not required to by your clients or your growing technique. Root plugs work much much better, and you dont need to feed for weeks not days. Hope this helps ! 🚀
