Hey 👋
You can definitely heal some wounds with tape, if you had a branch break for instance you can help seal it to heal and hold in place. Other wounds you'll want them to just heal with air, but support them if they risk falling over in any way.
I know you can sometimes use aloe vera plant to help aid healing. And you may want to consider using a silica product in your grows since they help to build resilient, strong plants.
Happy growing. ✌️
