Ok so you have your tent set up? then you should think about raising the ballast of the floor when you do.
At very least you need extractor fan that can do a full air cycle of your tent at least every 3 minutes, temperature/humidity gauge, nutrient wand, nutrients, mixing bucket, A proper timer for the ballast/light(THIS IS ESSENTIAL), Pots, Soil, Seeds, PH testing kit. GET A BOOK I bought the cannabis grow bible and imo its a life saver!!
Not Required but you might want them.
Intake fan, carbon filter for exhaust fan(will only work if you can create negative air pressure with your ventilation system),
DO NOTS for the 1st GROW:
Do Not, get excited and destroy your plants.
