1st grow 500 watt hps 3ft by 2ft closet. 2 dwc plants 50 days old autos just starting to bud. There about 4 feet tall. 2 plants was 2 much for the closet so i had to leave the door open n build like a tent out of boxes and blankets. To make more room. The plant thats directly under the light is about a foot taller... I should probably switch them right. The tall plants also blocking a little light from the other one
