DIY DWC propagator. Just a little 2 gallon document storage box. I love the name of it "Really Useful Box" you ain't kiddin ;-) Small single output pump and stone. Small fountain pump split for simple top drip system and circulation. Installed tube for res level. Holds two 3in net pots but could have easily gone up to 4 or even 6. I keep a 1/4 strength solution about a half inch below the pots. Using a rockwool cube with hydroton. This is a photo Indica bag seed I sprouted for fun last week to test the box. Already have a 1.5in root out the bottom and several others about to find the water
