maybe all this time the plant has just been filling up the pot with roots...I bet if you throw 50 dollars worth of fluro lights on it you will see a great improvement in growth. Or you could spend about 150 on ebay get a 400 watt HPS and really turn it into a PLANT. Like I said before plant looks great....but I bet some light would give it a huge growth spurt....root system is probably excellent. It does kinda look like lowrider....but hey light never hurts anything!! Good luck man
