Shot glasses with Luke warm water and keep them around 85 degrees. Once planted I keep them around 75-80 degrees with 60-80% humidity and spray them twice a day. Also keep fresh water in them every 24 hours that’s if they aren’t cracked open by then but my method works and you usually get 100% success rate out of it.
