A basic, low-cost, reliable, indoor garden is a controlled environment typically in the form of a tent inside a room, inside a garage.  You have one or two AC-powered ventilation fans, recirculating and/or one is the intake and the other is the exhaust.  You have two super bright fluorescent lamps connected to a mechanical/digital timer controlled AC outlet providing the plants with their appropriate light-cycle.  Your plants are contained in soil, or a basic deep water culture hydroponics system. A large plastic reservoir with multiple grow baskets containing clay pellets partially submerged in the nutrient solution being aerated by an aquarium-style air-pump that’s connected to an air-stone, creating bubbles, preventing stagnation, keeping the culture healthy.
