So I want to think that all phenos from all strains can be made small or large with just lighting. I mean my plants never get close to my 1000w, its like they try to, but once they get about a foot away, they stop lol. . no matter if its veg, or flower. I crank up my led veg light and lower it to actually stop the strech. Sure it burns the top a bit, but in veg it can all be cut off, but down below shit is growing fast too. I guess im leaning down the area of not enough light to say it grows lengthy. I only say that cause I see leds lol, i dont like them. .yet. .. Im more less gonna try 2, 1000w HPS in a 5x5 because I am trying to keep them low.
