i guess it depends on the widow .. lot of so called widow circulates around..infact im runnin 4WW myself..and i gotta say im not impressed with these clones..not 2say the og ww isnt the shit..but my ww isnt packing on wieght like the rest of my strains..so it can depend on so many factors its not funny..a yield guestimate would be much easier with pics.. and youll obviously get more if u can get them in large pots 7gal+ and veg for another entire month..id say 12'' clone potted from club /caregiver immediatly thrown in2 flower can give 1-2 oz and be 3ft+ tall on chop..thats all rough estimates. edit: i dont know shit bout coir..so dont know bout ur contanier size for yieldign a qp
