A grow tent, a light, pots, soil or coco, an intake fan, an exhaust fan, and an oscillating fan for airflow movement in the tent. Just be careful ordering the smallest tent because when I tried to order a veg tent I ordered the wrong size and the tent was supposed to be 6 feet tall, but it was only 3 feet tall lol....
I set it up and it looked like a little mini fridge! I couldn't fit the plants in it because the light hung down so far hahaha
