White Widow Auto WoHoo

4th week and 3 of four plants showing pistils. All are in LST. Adding big bloom into the nutes. On the side note I have almost finished the grow room. Added the portable ac and have it so it vents outside now. The portable ac actually serves a few functions. It creates negative pressure as it takes air from room and exhausts it out a 4 inch hose (how convenient). So i added a 12x12 intake vent that holds an air filter. Using one that traps pollen, dander, ect. should give good clean air to the girls.
