Potential yield

Too many factors to consider, don't worry about it, just enjoy what you get. The buds usually lose around 70% of their weight when drying so you could wet weight it after chop then deduct 70% for a ballpark figure but again its not that accurate, each strain can have different bud density, different feed regimes can make big differences etc. We all want good yield but it can be very frustrating chasing it, opt instead for clean flavourful smoke as a target and I guarantee you will get a better sense of achievement and at some point you will find that genetic that has it all including yield. I dont bother
