I don't have any personal experience with it but my brother and his friend do. They say it has a great yield, superb high and is great for a cash crop.
Yo bro, one of my growers is doing that one now, the Auto version tho, here it is at 52 days old, in a 25L Square Pot, growing under 3 Eshine LEDs' (640 W total) with two other slightly older Automatic plants.
Personally, I wasn’t too impressed with the potency, but it yielded quite well and was not a difficult grow at all. Not bad at all, but also not very close to on par with most of my better quality strains.
