yup turn the pump on and let it run.I actually went ahead and had someone want to buy a built 1 today so I built 6 more total so if anyone is looking for a brand new one unused I can sell them with pump , without pumps for less and with fox farm nutes or not.1 ready to go out the box for $70 plus shipping with the pump or $45 without the pump.I can add the 3 pack of Fox Farm nutes for another $39.99 as thats what I can get them locally for no mark up.So thats a 20 gallon setup with the 6 mister setup, 3 inch net pots 6 rockwool cubes to start you out, Bag of clay pebbles for 6 net pots,new pump all connectors and adapters.All I need then is a zip code and I can check on shipping which Ill send anyway you like ups, fed ex usps cheapest or fastest your choice.Just have to let me know so I can order a pump which will take about 7-10 days to come maybe faster. I can build them in different sizes upon request prices vary slightly for bigger.Can do 4,6,8,10, or 12 site setup..Anyone interested just let me know
