You should be fine without green cure. I once tried spraying with green cure to kill spores, let them dry in front of a fan, harvested, immediately rinsed in the shower, and put back in front of a fan for the night.
I don't know if it helped at all, but it didn't get worse, and it didn't ruin my smoke or degrade my quality. Hydrogen peroxide baths are popular but it really beats up the buds Imo, I lost a lot of frost doing that. The humidity and temp of your drying space is the most important thing when trying to keep rot at bay. If you don't have bud rot you'll probably not encounter any issues.
