auto-blueberry ?

Anyone know this strain does it stay short during the first 3 weeks or is it supposed to strech out some ? I got a free seed from SoS and was wondering if it is even an auto at all n any info on this would help .

If this is the Dutch Passion / Dinafem strain it will stay pretty compact unless the lighting is not strong enough in which case it will stretch like anything else. Its a pretty good strain, not a great yield but a good strong smoke.
