Growtronix - Best Grow Room Controller

Growtronix can control every aspect of your grow room or rooms, and it can be used to monitor and graph out all environmental variables in real time, with built-in web server so you can monitor and view your plants, and control your grow room or rooms from the Internet.
My system is in like new condition, everything is in prefect working order and in great shape.
For the Growtronix system the purchase price was about $1,400. I would sell everything for $575, which is the price of the base system alone at its current sale price.
