This is the ultimate of our systems in my opinion. Its a take on the 2 foot and 3 foot boxes we've always sold, but better. This is 4 feet tall, in the middle of the box is now a removable shelf for amazing vegetative growth unseen in other small personal grow cabinets such as the cash crop. This allows users to bring their system up close to lights until ready for flowering stage. At that time, simply remove shelf and start your flowering stage at the bottom of the cabinet. Change out to flowering bulbs(included) and change to flowering nutrients(also included). This is a 6 plant hydro system with net cups, medium, grow and flower nutrients, intake and exhaust fan with carbon filtration, lockable snap lock doors for ultimate tightness. Allows more yield, bigger plants, at a fraction of the cost of other peoples large units. You get snap locking doors, carbon filtration, 6 plant grow system, grow and flower bulbs, net pots, seed starters. Will grow better than the aerogarden deluxe guaranteed or your money back. This unit compares to the cash crop 2.0 and other grow boxes on the web for less. This one is a foot taller also. You wont find a better made, quality, turn key system at this price anywhere, period. Everything is included to grow amazing plants except seeds.
