This system features 6 3" net cups strategically place for ample grow space for starters, clones, smaller plants (your greens etc), while still leaving room for a large access panel to do any maintenance or observation.  It also has a built-in water level indicator, multiple ports for air stones, as well as enough room to get a hand between the rows of your plants. The reservoir has a heavy-duty rubber mat to cover the access panel and four handle clamps to secure a light tight environment and can hold around 4 gallons of water/nutrient solution. The system includes the versa-air pump (63 gallons per hour), 2 air stones, enough clay pebbles to fill each net and six starter rockwool cubes.
