The document discusses an upcoming workshop on urban agriculture. The workshop will cover topics like permaculture design principles, edible landscaping, LED grow lights, solar greenhouses, living walls and rooftop gardens, and social enterprise. It provides details on the schedule, location, and contact information. The workshop aims to teach participants how to turn an urban homestead into an integrated and sustainable social enterprise through urban agriculture techniques.

2. Workshop Agenda
• Permaculture Design Principals
• Edible Landscaping
• LED Grow Lights
• Solar Greenhouses
• Living Walls and Rooftop Gardens
• Social Enterprise
• Urban Homestead Design
3. Permaculture = "permanent" & “culture."
Its roots evolve from
• the design of sustainable
agricultural systems,
• techniques and principles
of ecologically designed
communities,
• urban restoration and
self-reliant regions.
in such a way that all life benefits
(i.e. human and non-human).
4. Permaculture Ethics
and Guiding Principles
Permaculture Ethics
• Care of land;
• Care of people;
• Reduce
consumption and
share surplus.
5. Principle 1:
Ethics, care of land and people
Caring for the land,
people and all life
would be a
step forward for all.
6. Principle 2:
Relative location
The strategic selection
and placement of
plants, animals,
structures, etc., so that
the yields of one
element become
the requirements for
What does the chicken produce that can be used by
other elements in the design?
another element
7. Principle 3:
Multiple functions, single element
Every element should
provide at least three
functions.
• A "living" fence can act as a
barrier, act as a windbreak, and
provide food and medicine for
the family.
• When designed into a system,
bees can provide; food, income,
and pollination.
8. Principle 4:
Multiple elements, single function
Multiple elements for a single
function adds diversity and makes
the local ecosystem more
resilient to environmental
fluctuations.
For instance, for heating a structure,
the elements would include:
• body heat from animals,
• south facing windows, and
• the use of thermal mass to store
the collected heat.
9. Principle 5:
Efficient energy planning
The goal is to help reduce
the amount of effort
(primarily human labour)
The property is divided into
zones related to how
frequently each zone is visited.
The more intensive the activity
the closer to human habitation
it should be.
10. Zones and Sectors
Sectors take into
• Zone Zero - Home consideration the
• natural elements and
Zone One – Home Garden
wildlife.
• Zone Two – Home Orchard
• Zone Three – Farm
• Zone Four – Managed Forest
• Zone Five - Wilderness
11. Principle 6:
Biological resources
• Move away from
monocultures.
• Mimic the diversity and
resistant qualities of
natural systems.
• Focus on utilizing energy flows (water, wind, etc.)
that pass through a region.
12. Principle 7:
Energy recycling
Energy flowing through the
system is used in many ways.
• Water systems might create
keyline swales and dams as
it passes through the
landscape.
• Energy recycling would
also include recovering
biogas from waste and
orientating structures to
obtain maximum solar gain.
13. Principle 8:
Maximize diversity
• Build stability by maximizing
diversity, in terms of plants
animals and in terms of
livelihood.
• Maximize the number of
beneficial interactions
• Create as many microsites,
and habitats as possible by
increasing edges, patterns,
and plant guilds.
14. Principle 9:
Stacking
Stack elements in vertical
and horizontal space as
well as in time to grow as
much as possible in a
vertical plane so larger
areas of land can be
put back into a more
natural state in the hope
of healing the planet.
15. Principle 10:
Appropriate technology
Use implements that are
E.F Schumacher,
locally made, can be ‘Small is Beautiful’
repaired locally, and used
with the skills of local
people.
Also, have less reliance on
fossil fuels.
16. Principle 11:
Scale
Return to smaller scale
technology and a balance
with technical diversity.

17. Mollison's 7 Permaculture Laws
• (1) Everything is
connected to
everything else.
• (2) Everything gardens.
18. Mollison's 7 Permaculture Laws
(3) Yield of a system is
theoretically unlimited.
Limited only by the
imagination and
experience of the
designer.
(4) "Protracted and
thoughtful observation,
rather than protracted
and thoughtless
labour."
19. Mollison's 7 Permaculture Laws
5) The problem is in the
solution, or everything
works both ways.
Problems turned into
assets and wastes into
resources.
(6) Stay out of the bush; it
is already in good order.

There is a capacity for mature 400 plants, using the same systems,
in this room and still have room for a four trier germination rack
72. Solar Greenhouse Rules of Thumb
Design:
•If the greenhouse is longer than 16ft., the East and West walls should be
solid.
•For maximum solar heat gain, the glazed, south side should be tilted to the
same degree latitude you are located at, plus 15 degrees.
•For maximum solar benefit on plant growth the glazed, south side should be
tilted to latitude plus 5 degrees
•Snow can reflect 50 more total radiation through a vertical wall than a tilted
wall can transmit.
•The angle of the north roof should approximate 30 degrees to reflect light
down on the inside.
•There should be a double doorway/vestibule on the main entrance if the
greenhouse is not attached to another building.
•Insulate with R-20 in the walls and R-40 the roof.
73. Solar Greenhouse Rules of Thumb
Foundation:
•For a greenhouse less than 300sq. ft. should be attached, a pit or dug into
the side of a hill.
•The floor in a five foot deep pit (no wider than 12ft.) will average 40-50
degrees Fahrenheit, year round; providing warmth in the winter and cooling
in the summer.
Glazing:
•Glazing should equal at least 1/4 of the total floor area.
•R-12 insulation over the glazing for 14 hours will reduce the buildings heat
loss by one half.
•The south wall should be double glazed.
•The east and west walls should be a triple glazed.
•The north wall should be insulated and painted white.
74. Solar Greenhouse Rules of Thumb
Heat Storage:
•Choose building materials that absorb heat quickly.
•Use as much storage as possible.
•Use at least 1/2 cubic foot of stone or 4 gallons of water/sq.ft. of glazing
•Insulate the perimeters of the foundation.
•If it gets above 90 degrees in December, January, or February more
storage is needed.
•Provide heat storage directly below plants.
•Rocks 3/4 of an inch to 1 1/2 inches in diameter are most suitable for
storage bins.
•The surface area of the storage should be at least equal to the floor area.
Location:
•The greenhouse should face within 30 degrees of true south.
•No obstruction as tall as the greenhouse should be within 4 1/2 times the
height of the house.
•Provide a wind break on the north side with trees, buildings, or hills.
•If the floor area is less than 200sq. ft., the greenhouse should be attached
to another building.
75. Solar Greenhouse Rules of Thumb
Plant Care:
•If the greenhouse faces 15 degrees east of south, it will benefit plant
response to light intensity.
•Red and blue light from painted walls will promote healthy growth and
earlier flowering.
•Plants prefer fluctuating temperatures from day to night.
•Water once/ day during summer and once/ week during winter.
Solar Heat Benefit:
•During the day a greenhouse can put excess heat into an attached
building heating an area over twice its own size.
•A greenhouse will raise the humidity of an attached structure about 5
percent.
•An attached greenhouse is usually cooler than a freestanding structure
since 10-15 percent of the sun's radiation is blocked by the adjoining
structure.
76. Solar Greenhouse Rules of Thumb
Ventilation:
•Vents should equal 1/6 of the floor area with uppers of 1/3 larger than the
lowers.
•Fans regulating air flow should circulate four(4) cubic feet per square foot of
glazing per minute.
•Low vent windows should swing open at the top to aid thermo-circulation and
deter low flying insects from entering the house.
•Upper vents should be located along the upper ridge or on opposite side wall
that a lower vent/door is located.

sun, wind, biology, and architecture on behalf of humanity.
