Put the lid on, making sure that the plastic skirt (if required) falls into place. Insert the cups and fill them with a layer or two of your growing medium. Run the pump and make sure that the medium is getting moistened through the holes in the cups.

You can pull out the cups as the pump runs and check for water droplets on their outside too. The medium only needs to get slightly moistened so that until the roots grow down and out of the cups, they can feed. You can adjust the relief valve to increase/decrease spray.

After your system is complete and checked out, you can prepare your seedlings for transplanting into the system. We planted this array of salad greens, tomatoes, basil, oregano, dill and sage about three weeks before transplanting.

You will see that our seedlings sprouted in both rockwool cubes (on left) and in the Cocofiber (on right). Cocofiber needs to be rinsed off the roots before transplanting into the cups. All in all we have determined the Cocofiber to be better for sprouting seeds than rockwool but it is much messier than the rockwool cubes!
