These items are used but are in like new condition. I started a hydroponic project in my basement & got bored with it so I took it all down & am selling these items. If you have any questions let me know. The items include 5 air pumps that connect to air stones, PH meter to test the PH in the water, a TDS meter to test the nutrients in the water, two times (one of the timers has two outlets & the other has one), three air stones & a digital thermometer so you can test the temp of the water. Each pump has two outlets. All these items are great for a deep water culture system or 5 gallon bucket system. I just didnt have the patience for it. All of these items cost over $80 when I got them. Thanks
