lots of grow gear

Not growing anymore, looking to get rid of everything. Everything except the tent and hood were used for two runs and the bulbs were only used for one. I`d like to sell all together, but I am willing to separate, I will cut a deal if you buy more than one piece at a time. All prices listed are OBO, I`m really just trying to get rid of all of this, so feel free to send any offers you may have.
