mine just blew up right away....at first, it popped up, took a day of sitting, looking about the same, then, boom! it was doubling in size daily....and hasn't showed signs of letting up. dude, mine is 3 weeks old now, and its got pistils on it already! such an amazing plant. I think my next one will be a photo period tho, cause I don't like the idea of losing potency.....I have heard a lot of mixed feelings on these autos....for sure they are fun, and I have yet to judge the taste and potency. I am kinda basing my opinion of autos on this one grow./...... looking to place another order today, but I can t decide what to pick. there are just to many choice! waya way to many~! im thinking maybe critical kush, or if I stick with autos, maybe short rider. I have heard a lot of mixed reviews on this one....I think the bad reviews could had been inexperienced growers, that didn't do it right. idk, like I said, WAY to many damn choices!
