Growers kit: Ballast, Tank, Controller

Hello,
I have a few things for sale to grow for yourself. I am willing to sell them separately but would prefer to group it and sell all together with a group discount price. Everything is practically new and babied with the original packaging. Should you have any question please send me an email and I will get back as soon as I can. Please only serious buyers.
Thanks for looking,
