No one is going to be able to tell you by looking at the picture. You need a scale. Someone might be able to guess, but thats all it would be. A guess.
It's gonna shrick 80% weight when it dries. it always feels like and weighs out to alot when it's wet. But it's shocking how much lighter it get's... If that bud is say 40g's wet it'll probly end up being a quarter.
Nice job for your first run man, that's some solid bud. I pulled a bud about the size of the 12" you showed and it weighed out to over an Oz dry. I suggest buying a scale man, they're about $10 on amazon.
Ah it's getting dry. I did harvest her early but she was a sativa dominant and would have died or been infected beyond salvage if I let her go the extra month. She is so damn fluffy I probably got like 2Oz if lucky
