ULTRaponics Elbow - $4.95 each
Two ULTRAponics Elbows are required for both of the outside/end DIY GroTubes in a multi-DIY GroTube hydroponic system when using both the Flood and DRip Methods. In addition, any inside DIY GroTubes in a multi-DIY GroTube System will require two Tees. When using only the Drip Method, only one is needed for each DIY GroTube,
Tees and Elbows interconnect DIY GroTubes together in a multi- DIY GroTube hydroponic system and, then, either connect to the pump in the reservoir on the shorter Drain side or, in the Flood Method, connect to the taller Fill side to drain back into the reservoir.
