[[Image:hangthyme.jpg|thumb|right|Figure 2: Front view of the Hang Thyme design]]
Our final design, as seen in Figure 2, is titled the Hang Thyme.  The Hang Thyme is a hydroponic green wall that is used to grow herbs in minimal amounts of space; utilizing energy readily available in the natural world.  Such energies include gravity (drip irrigation system), sunlight, and heat from the sun.  The green wall can either be left free standing or can be hung.
[[Image:HangthymeFrame1.gif|thumb|left|Figure 3: Side view of the frame with hinges.]]
[[Image:HangthymeFrame2.gif|thumb|left|Figure 4: Front view of the frame.]]
===The Frame===
The frame that supports the nutrient reservoirs and growth medium are essentially two bookshelves constructed with 1x4in pieces of wood.  The dimensions of the box frames are 4ft in height and 2ft in length.  As shown in Figure 3, the frames are connected by hinges that allow the unit to fold into itself, providing an easier means of transporting or shipping the model.  All wood used in construction is first finished with shellac and later lined with plastic to prevent wood rot from constant exposure to moisture; also displayed in Figure 4.
===The Growth Medium===
The Hang Thyme utilizes Rockwool (also known as mineral wool) as its growth medium.  Rockwool is constructed with fibers made from natural or synthetic minerals.  However, due to its high alkaline content, the Rockwool tends to turn the nutrient solution basic and can alter the pH.  For this reason it is essential that the Rockwool is allowed to soak at least 24 hours in water with a low pH to neutralize its basic qualities.  Rockwool also has the capacity to retain both air and water for hours up to days, allowing healthy root growth.  Spacing between the fibers will enable the roots to spread and grow, increasing plant stability.  Another quality of Rockwool is that it will not absorb the nutrients in the solution and therefore allows the nutrient solution to be recycled through the living wall.
[[Image:Reservoirs.jpg|thumb|right|Figure 5: Water reservoirs demonstrating their drip irrigation system.]]
[[Image:Externalsupport.jpg|thumb|right|Figure 6: External support in use.]]
===Nutrient Reservoirs===
Two buckets are attached to the frame with fitted structures to hold them in place.  The top reservoir has 1/16” holes drilled on the bottom center to allow drip irrigation.  The holes are spaced 4” apart, regulating water flow, which in turn, keeps the growth medium constantly moist (please refer to Figure 5).  The top reservoir is attached to the frame by two wooden tabs, one of which is hinged, allowing easy setting and removal.  The bottom reservoir collects excess nutrient solution runoff that can be recycled back into the top reservoir.
===External Support===
As previously mentioned, the Waterpod Hang Thyme can either be left free standing or hanging.  If one would prefer to leave the device free standing, we have included a support constructed from a 4”x4” beam that attaches to the back.  As shown in Figure 6 the Waterpod Hang Thyme can be opened to a 90 degree angle with the support in back creating an x like shape.  This shape provides sufficient support to both the front and back ends of the device.

The unique simple hydroponic design consisted of great ideas from each member as well as other countries that do not have the perfect weather, soil and resources for agricultural development. The though and motivation of the design implemented innovation and simple thinking. The aspect of creating and building the simple hydroponic design consisted of resources from books, world wide web, and from the help of the Water pod clients.
Our Goal of the design is to design a system that would use no electricity, use less water, and easy maintenance by using simple tools. In order to achieve our goal we communicated by collaborating with local hydroponic stores and system analysis through research. The design also focuses on changing the systems growth medium, and nutrient solutions based on the type of plants that will be used in the system.

Abstract

Greenapple1.jpg

The Waterpod was created to demonstrate alternative living models for future living through water based communities. These communities would be self-sustaining and nomadic; allowing for growing populations to thrive in an innovative and more sustainable manner. As a way of inspiring innovation through sustainability, the Waterpod contacted our team, Green Apple, to design and build a simple hydroponics system that would be utilized on the pod for the six month period of their demonstration of self-sustainability. What resulted was the Hang Thyme hydroponics system; a hydroponic living wall that doesn’t require electrical energy. The living wall design is easy to build, implement, and maintain sustainable agriculture.

Final Solution

Figure 2: Front view of the Hang Thyme design

Our final design, as seen in Figure 2, is titled the Hang Thyme. The Hang Thyme is a hydroponic green wall that is used to grow herbs in minimal amounts of space; utilizing energy readily available in the natural world. Such energies include gravity (drip irrigation system), sunlight, and heat from the sun. The green wall can either be left free standing or can be hung.

Figure 3: Side view of the frame with hinges.
Figure 4: Front view of the frame.

The Frame

The frame that supports the nutrient reservoirs and growth medium are essentially two bookshelves constructed with 1x4in pieces of wood. The dimensions of the box frames are 4ft in height and 2ft in length. As shown in Figure 3, the frames are connected by hinges that allow the unit to fold into itself, providing an easier means of transporting or shipping the model. All wood used in construction is first finished with shellac and later lined with plastic to prevent wood rot from constant exposure to moisture; also displayed in Figure 4.


The Growth Medium

The Hang Thyme utilizes Rockwool (also known as mineral wool) as its growth medium. Rockwool is constructed with fibers made from natural or synthetic minerals. However, due to its high alkaline content, the Rockwool tends to turn the nutrient solution basic and can alter the pH. For this reason it is essential that the Rockwool is allowed to soak at least 24 hours in water with a low pH to neutralize its basic qualities. Rockwool also has the capacity to retain both air and water for hours up to days, allowing healthy root growth. Spacing between the fibers will enable the roots to spread and grow, increasing plant stability. Another quality of Rockwool is that it will not absorb the nutrients in the solution and therefore allows the nutrient solution to be recycled through the living wall.


Figure 5: Water reservoirs demonstrating their drip irrigation system.
Figure 6: External support in use.

Nutrient Reservoirs

Two buckets are attached to the frame with fitted structures to hold them in place. The top reservoir has 1/16” holes drilled on the bottom center to allow drip irrigation. The holes are spaced 4” apart, regulating water flow, which in turn, keeps the growth medium constantly moist (please refer to Figure 5). The top reservoir is attached to the frame by two wooden tabs, one of which is hinged, allowing easy setting and removal. The bottom reservoir collects excess nutrient solution runoff that can be recycled back into the top reservoir.


External Support

As previously mentioned, the Waterpod Hang Thyme can either be left free standing or hanging. If one would prefer to leave the device free standing, we have included a support constructed from a 4”x4” beam that attaches to the back. As shown in Figure 6 the Waterpod Hang Thyme can be opened to a 90 degree angle with the support in back creating an x like shape. This shape provides sufficient support to both the front and back ends of the device.

Operation Instructions

Figure 7: Reinserting Rockwool slabs.
Figure 8: External support in place.
Figure 9: Placement of nutrient reservoirs and catchments.
  1. Remove the Rockwool slabs from the system and allow them to soak in the nutrient solution for 24 hours.
  2. With the unit flat on its back, the black mesh strips are on the ground reinsert the slabs into their original formation shown in Figure 7.
  3. When the slabs are in place, pull the unit up right and open it up until it’s approximately at a 90 degree angle and place the external support in the slot as seen in Figure 8.
  4. Insert the two nutrient reservoirs and the nutrient catchment systems as shown in Figure 9. The two top reservoirs can be inserted by lifting up on the wooden tab and sliding them into place.
  5. To plant seeds holes need to be drilled such that the seeds can be deposited. The depths will vary based on the choice of plant.
  6. Once the plants are in place the growth medium must be kept moist. This can be done by filling the two clear containers at the top with the nutrient solution. Pre-drilled holes will allow for the nutrient solution to trickle down onto the medium where it will be absorbed and transported throughout the medium via gravity.
  7. When the two lower containers become filled they can be removed and the nutrient solution can be recycled into the top containers.
  8. The watering schedule will vary based on climate conditions, however the medium should be kept moist at all times.

Next steps

The Hang Thyme hydroponics system will be touring with The Waterpod in New York for six months starting in the summer of 2009.
