It should fall off on its own. Give it lots of moisture, maybe put it under a humidity dome. If you really want to, gently give it a droplet of water right on the helmet. I heard saliva works well too.
Helmet head is typicially a sign of planting the seed to shallow. So keep that in mind for future grows.
Good luck mate!
@@RiseFromTheFlames, I have been keeping it under a dome and it has had moisture in the dome.. I will try those ways and let you know!! Thanks for easing my mind.. I will pay more attention not because last time we went to deep 🤦♀️ But hopefully grow #2 goes smooth and this one will be bigger and better!! 😄
