nope, also if your gonna try the 2liter bottle thing i wouldnt advise it, i used 3 liter bottles and they still went root bound, i had to tape different pots to the bottom for the roots to grow (i know its ghetto but it works, lol) didnt wanna risk them going into shock by transplanting while flowering,.. i also vegged mine for 2 weeks and i'd say it was worth it,
