Bell Syphon for growtray

thingiverse

PRINT UNSUPPORTED !!! << i made it so Low height ( 3 inches ) Bell syphon for a grow tray . I made this a while back and have been thoroughly testing the design , so far it's worked straight off the bat.. . I have two of these running trays full of clay balls on a trickle fed overhead cistern setup , the cistern fills slowly from a small pump , then dumps to the trays , which fill and dump back the reservoir and pump .... I'd love to see makes of this .. it works great .. the aperture is designed to take standard hose pipe .. i use a short length down into the water of the reservoir , the air pressure enables the burp prior to full syphon mode... You can use a two pence piece and a sharpie for the cut template ..
