I am assuming english is not his first language give him a break. here i will translate in to grower speak.
"I germinated the seed on 8/13/14, she is not about 1 meter in height, I think the plants yield will be enormous and I have fallen in love with the strain. Has anyone had experience in growing this strain if so how long did you let it go before chopping?"
No I have not grown the strain, if it is a super auto then it is not unheard of for them to go 90 days. See what the seed bank website says, and check the trichromes 1 week prior to that date. In my opinion harvest time varies for growers dependant on how they like their smoke. No one can answer that question for you IMO.
