Guesstimate

Just wondering if any of the old hands on here could guesstimate how much this girl will yield by looking at it;would two zips be out the question?!

Probably close

One zip.......

From what I can see my guess is dry and cured in the 1 to maybe 1 1/4 weight

maybe 1.5 ounces
Dr. Jekyll

it will be 1/4 pound if you don't dry it

Its getting close to chop time,but Im thinking another 2.5 weeks,will she gain a bit of weight in that time?

You will gain some. Is this a sativa heavy plant as it looks like it? You didnt count the first 7 days of 12/12 as flowering right as day 8 is day 1 of flower counting.Then id guess 9 plus weeks for a sativa heavy plant

it will pull 1 gram. you can never tell unless you have grown that exact pheno multiple times.. Density can change while drying. some buds shrink more than others too..
