All my plants are about 19-22 inches tall. They have been veg from seed. They have been vegging for about 2 months. 36 plants total some are sativa and some Indica. I am running 2 1000w hps lights on a light mover and the room is about 12x15. There on 3 gal grow bags. My air flow is pretty good, my temperature is aournd 70-85 and humidity is around 50-70%. Im using Frogs soil and Envy nutrients. How tall should my plants get when there finish. Thanks in advance...
