Superior Cell Tethered Technology allows the user to move each cell up to 2' in any direction, even while in the middle of a grow cycle. Allows the user to increase wattage and footprint when nessesary. Compatible with 400w (3'x3' tent), 600w (4'x4' tent) and 1000w (5'x5' tent) grow spaces. Adjust plant spacing at anytime. AquaBuckets is a Recirculating Direct Water Culture (RDWC) System that uses a reservoir to provide water for multiple buckets. 120 mesh filter attaches inside the mixing cell. Constant recirculating oxygenates the water and ensures a good mix of nutrients, CF and stabilizes PH throughout the entire system so testing is required only at one point.
