Max. Size=Max. Yield. The GIGANTEUM 1 was design for the grower  who demands an ample rootball necessary to achieve monstrous trees or plants. Personally, I have grown over 5 foot high plants, from seed in a matter of  a few months. This Aeroponic system includes everthing you see here, 2 pumps, top feed harness, internal spinners, grow rocks & rockwool.
