I have a 60x60 grow ready to start. My question is? What ventilation should I use? Is it good to have something certain from the beginning? The light is the Smith 150w LED.
I'm watering every two days with 2 liters of water, is that too much? The soil seems dry when I go to water and the pots feel light. But I'm always in doubt.
I do one watering with nutrients and one just with water.
