I want to build a flowering box for 8 3ft(at harvest) plants that is 3ft wide 2ft deep and 6ft tall Is this enough space??

I will use the bottom foot for my ebbnflow reservoir, the middle 3 feet for plant growth and the top 2 feet for lighting.

makeing it 36 cubic feet of space all together (30 feet if you don't count the reservoir area) and 18 cubic feet for the plant under the light

I want to ventilate using a squirrel cage fan that is pulling air from a hole in the light reflector,put an intake hole near the plant base, and of course use mylar over all the walls.

If i can keep the outer room the box is stored in at below 70 degrees fahrenheit do you think it will be a good plant environment.

I'm not sure about humidity levels in the room yet but will get a humidifier or dehumidifier based on what i find...also I hear that ideal is between 50-80% what do you think is best and at what temp??
