the other night i was burning the midnight oil and ciphering on how to get reservoir solution to drip into the tops of the net pots in my bubbleponic units until the roots have grown down into the solution. the issue i was having is that the thought of buying 6 water pumps for 6 units and running the splitters, having power cords coming out of the units and running the cords, blah, blah, blah... yuk then it came to me like the hot kiss at the end of a wet fist... bubble lift the theory that air will lift water so i devised these cool, simple, inexpensive bubble lift drip emitters. they use air to pump the nutrient solution up out of the emitters. they can be used instead of an air stone at transplant time in a bubbleponic unit until the roots have grown into the solution. it is possible that these could replace the air stones in bubbleponic units entirely if the solution is being aerated enough. this would have several advantages including practically eliminating root tangling with air delivery units (stones, diffusers), simplifying design and materials, and ease of maintenance. this is a prototype. use black vinyl tubing, a smaller diameter lift tube (maybe 10mm interior diameter with 4 mm air tubing, more efficient perhaps), and a water tight non-reactive stopper (not wood). if you drill a hole in the bubble lift tube slightly smaller than the air tubing, the compression fit will seal the connection from water leakage to use simply insert the air tube into the bottom of the bubble lift about 3 inches and submerge into the solution which will then flow from the emitters in spurts and gurgles, apparently rather highly aerated. i drilled a hole in the top of a unit and slid the bubble lift down in, up to the emitters. there are 4 emitters because that's what i needed. parts: bubble lift drip emitter unassembled 1.jpg assembled: bubble lift drip emitter assembled 2.jpg working video: bubble lift drip emitters.wmv this unit was receiving 150 gph of air in a 12 gallon res have fun!
