Grow tents let you grow plants hydroponically. A typical grow tent kit includes lights, a watering system, trays, and everything else you need to grow plants without soil, indoors under greenhouse conditions.
Lights for energy, a fan for air circulation, pumps to circulate nutrient-rich water, all of this is part of a grow tent. The hydroponic farmer supplies the seeds and the care and attention. With everything going to the plants scientifically controlled, you are sure to get a good result.
