[DESIGN] - High-Pressure Aeroponics #25
Comments
(Potentially) useful resources: |
Potential pump options: Option 1: Onsen 1L tank + External Pump Keeno pump is from Amazon. Is rated for 116 psi - 5L/min. Other similar pumps available. Similar pump from SailFlo. Option 2: All in one bladder tank + pump. - EDIT: these are just tanks |
Good resource/overview on HPA: https://www.aeroponicgrowers.com/high-pressure |
Frame/housing problem: how do we a) mount the nozzle hardware under the grow tray, and b) contain the spray? Potential solutions in existing NASA space aeroponics work? |
Potential solution: A square bag could be made to fit underneath the frame and it can be held in place by securing it to the sides of the aluminum extrusion. This would encapsulate the nozzle/mist and have the added benefit of also being flexible (in reference to the accordion idea). |
Top Options: Nozzle: |
Just realized this issue should cover testing as well. |
Bought fittings today. Will open a new PR to a) update BoM and b) test. |
@nchareunsouk is gathering a list of nozzle alternatives. |
Ordered new nozzles, fittings from McMaster Carr |
@nchareunsouk Can you find the source where it mentioned the .6mm nozzle opening? Preferrably the NASA document |
Re-opened for remaining tasks |
Completion is tracked in the linked issue.
Design Scope
Design a high-pressure aeroponics system for delivering pH- and temperature-controlled nutrient-rich water mist to the root zone.
Purpose
The purpose of the aeroponic system is to deliver water to the root zone as a fine mist for plant uptake, while controlling the water temperature, pH, and concentrations of various nutrients.
