not so much, if u throw a pic up idc, its the i have, X amount of plants this tall and this wide, blah blah blah, its pretty much useless info. theres no magic yield equation to punch those numbers in and get a result. i agree with whoever said to go through with the grow, and see for urself how much u get, and thats a good bases to learn what a certain sized plant will yield in future grow. without pics, even with them most of the time, ur gonna have a whole range of guesses. person A said 1 oz per, while person B is saying 4 oz per,major difference between final yield. if u cant guess the yield urself, these folks over the computer screen certainly cant.
