Backyard Aquaponics & Hydroponic Veggie Garden

We take our grandson to The Imaginarium in Fort Myers Florida on a weekly basis.  He comes away enriched mentally and good and tired physically.

Modular Aquaponics at the Imaginarium - Urban Sustainability for Small Spaces
On display outside the main building is a modular aquaponics unit.

Modular Aquaponics, Growing fish, herbs, vegetables and flowers on a DIY scale
I really like this set up for producing food.

The fish (tilapia) are raised in a good size aerated and elevated swimming tank.
Modular aquaponics - the fish have plenty of clean water thanks to the plants!

The water from the fish tank is then pumped into the hydroponic vegetable growing tray.

Urban sustainability, basil, greens, marjoram, lemon grass and more grown hydroponically
Overflow water from the vegetable tray is drained into a surge tank (with many of the nutrients removed by the plants).

Modular aquaponics, the surge basin captures overflow from the hydroponic growing area
The cleaned (by the plants/herbs/veggies) overflow water is then pumped back into the fish tank and the cycle continues.

This unit is a great example of intense food production made from available materials in a limited space.

Urban Permaculture & Rooftop Gardens


We can defeat hunger in the Urban Core - on the roofs, on balconies, in small yards and across patios! Food is so easy to grow in the harshest of places, with little of no soil and even when water supply is limited.  All it takes is a basic understanding of the important factors impacting growth, such as wind, light and available water vapor.

Though permaculture has always addressed simple food growing principles, most of the time this focus has been about ground level growing.

Growing food on walls, roofs, buildings, and shacks up off the ground is important in the crowded urban core, high rises and slums.  Ground level food production is many times impractical in cities because of the lack of open land.  But there are plenty of walls and roofs to grow food on!

We believe educating the young about how to grow 'rooftop gardens is a way to capture their interest, create economic opportunity for them, create habitat, restore ecology and bring peace to the world.

Harvesting Green Roof Seeds, Educating the children
It is really exciting to see students become interested in urban agriculture.

Young children's minds are so fresh and thinking so quickly!  They see opportunities to improve and enhance our green roofs, living walls and rooftop systems.

Offering the next generation hope through empowerment is what we need to be doing every day.  Placing control of their food and water supply into our children's hands is so important.

Making educational videos about rooftop permaculture to teach the children.
It is a path to world peace and freedom from those who may want to try and control other's lives through food and water.

And growing food and recycling water does not have to be expensive or difficult.  This is why education is so important.

But we have a fight ahead of us.  Large corporations see opportunity through control of food, water, seeds and the knowledge of how to grow food and collect water.

The 'I don't have a green thumb and can not grow food' storyline is often repeated and many of the world have come to believe they can't grow sufficient supplies of food in the urban core.

We must show our children the path to breaking reliance from those who would control our lives and souls in exchange for food and water.

A small living wall or rooftop garden can provide enough seeds in a growing season to grow five more gardens the same size the following year.  Seeds are free.

Systems can be designed to cheaply capture and store water and to grow food on even shacks made from rusty tin.

The students harvested a giant luffa sponge from the roof this week.  Organic luffa sponges cost five dollars or more in the store.  The enterprising young person growing luffa gourds across the roof of their inner-city barrio could earn hundreds of dollars each season.

Plants not only provide food but they provide security, shelter and medicine.

I love Lydia Cabrera's quote I use over and over, paraphrased "there are more spirits in the plants than in the sky".

Aloe growing out of walls and on roofs becomes the local doctor's office in many instances.

Low cost Barrio-type house with living walls, food roofs & water recycling
Structure walls made from wire with grapes abundantly growing provides fruit, sugar, vine and community opportunities.

Rooftop beans and peas can feed the masses, not only providing daily food but offering up the following years crop of seeds.
Reusing water and controlling flooding

Native wildflowers planted across window openings and on the roofs and walls bring in the pollinators, crucial for food production.  One must have native wildflowers growing side by side with food plants.

Collectively we have found a way to travel to the moon, harvest the atom and talk across the globe.

But this awesome generation has forgotten how to feed themselves.

Now is the time to relearn.  Now is the time to show our children how to break leashes and create freedom.

Give me one month and the seeds I can carry in my pocket, a few wiling youth from the urban core and  the plants of medicine, food, fiber and economy will be growing across the landscape.  It can be done in a desert or a wetland, hurricane or earthquake prone areas.
We've answered the critics who say it can't be done, designed systems withstanding cyclones, created highly productive food systems in 30mm of sand, implemented bee hives on roofs, built water storage systems for practically no cost and are working now on a rooftop chicken system.



Control of your food is the path to freedom and peace.  Reliance on the corporations for food is the path to bondage.

Irrigation Efficiency, Rainwater Reuse

Water is such an important resource.

Urban Sustainability.  Recycling and attenuating rainfall is one of the many proactive measures we can take in helping conserve water use.
All too often I take for granted the necessity of clean water for all the earth and inhabitants thereof.

Clean water forms the basis for all life continuance and survival.  Many times we've mentioned here how Green Roofs and Living Walls, along with other measures of Urban Green can clean and filter contaminants from our rainfall runoff.

Add caption
Though I always recommend allowing rainfall to resupply the ground water, rain barrels can slow (attenuate) the rainfall runoff from roofs.  This allows the homeowner to reuse the rainfall for irrigation where then the water makes its way back into the ground.

Here is a pic from our Jacksonville Urban Farm where we captured rooftop runoff for reuse in our Urban Gardens.

Every bit of water recycle and reuse helps preserve our world's water quality.

Xeriscaping Importance and Water Conservation, Coastal Landscape Design

Xeriscaping is the practice of landscape design focused on the form of water conservation function using native or water conserving plants.


Florida Hurricane Landscape - Coastal Xeriscape plan.  One year post planting. No irrigation required.

Native plants are particularly useful in successful xeriscape design.

Irrigation is used primarily to assist during the initial period of the landscape plants establishing their roots and adapting to their new environment.

A successful mature xeriscape design should have either no added irrigation or at the most, very limited irrigation - such as micro-drip, for long term survival.

Regardless, xeriscaping design can be a challenge.

Coastal xeriscaping can present even greater challenges because of the added salt spray variable.

Here is an example of a successful coastal xeriscape project completed on Live Oak Island, Florida.

The first photo below is of the site after a tropical storm, debris littered across the water-front yard.
Hurricane damage, Site was cleaned and replanted with a xeriscape design

The second photo below is a snapshot of the new xeriscape landscape installed and mulched.
Xeriscaping, Initial planting installed only with temporary irrigation

Finally the very first photo above is of the landscape one year subsequent to the initial xeriscape plantings.

The plants include; Yucca filaamentosa (Adam's needle), Coral Honeysuckle (Lonicera sempervirens), Cabbage/Sabal palms and including Florida Friendly plants such as; agave, rosemary and more.

Intense Small Scale Urban Permaculture, Urban Sustainability

Truly amazing how much food can be grown in a tiny space.
Urban Permaculture Genius. Maximize food and flower production in tiny city spaces.
Tried and proven permaculture methods can ensure fertilization, efficiency, pollination, irrigation and wind protection for maximized food production.

Though the above may sound industrial or way too mechanical, with plants the ends result is beauty.

Beauty and food.  Sense of place and habitat for pollinators.  Soil stabilization and enrichment. Urban heat island cooling remedy.  Carbon and nutrient sink.  And much better than turf grass lawns.

Kudos to Judy Songer on one of her urban permaculture garden designs!

DIY Green Roofs for Rabbit Hutches

Here are a couple of green roofs for our rabbit hutches.
DIY Green Roof & Urban Permaculture - Stacking Example of Green Roof over Rabbit Hutch over Worm Bin
The roofs are made with available materials, most recycled and repurposed items.

The rabbit hutches are an example of the 'stacking premise' found in permaculture methods.

The top layer is the green roof which provides food, shade, shelter, cooling (and warming through thermal adsorption), and much more for the rabbits below.

The rabbits eat the forage from the green roof and drop rabbit pellets through the rabbit cages into the worm bins below the rabbits.  The worms then digest the pellets and produce mulch for the green roof.

Urban Green with recycled materials can be completed with minimal cost and surprising effectiveness!

Plants Can Clean Wastewater - Corkscrew Swamp's Living Machine

Audubons' Corkscrew Sanctuary treats its wastewater onsite with plants in a system know as a Living Machine.

Urban Sustainability.  Plants Cleaning Water!
The system has been in place for years now and has proven its functionality and reliability over time.

If you are ever in southwest Florida consider visiting the Sanctuary and viewing the Living Machine.

Plants are amazing.

Plants are key to world-wide sustainability.

Urban Landscape and Stormwater Integration

I always recommend integrating landscape and stormwater.  
Small SWMF feature incorporated into a landscape buffer.

Never could I understand why a developer or engineer would design a site with separate landscape and stormwater facilities, especially with the dire lack of urban vacant land.  

Such a waste.  

However some designers have their thinking caps on correctly and come up with some really awesome stormwater-landscape designs!  

Here is a photo of a small attenuation and treatment stormwater facility designed into the landscape buffer! 

The concept is quite simple and straightforward:
  • select a wetland tree or shrubs
  • build a berm around a small perimeter to receive rooftop of parking lot runoff
  • incorporate into the landscape design
  • achieve stormwater credit and landscape credit in the same amount of space.
Love to see more of this type design.

True Urban Sustainability Must Be Foot Traffic Based

Motorized vehicles have put us on a non-sustainable path towards societal failure.

True sustainability incorporates complete integrated pedestrian design - not just sidewalks
We no longer walk like our ancestors.  Instead the obesity epidemic exponentially blossoms and life expectancy may be declining.

Peak oil has come and gone.  Price instability associated with petroleum products is here to stay and impact pocketbooks.

One significant incident of oil or gas supply disruption would rock the markets and ultimately our existence.  We are walking a fine line and possibly unprepared for what could happen.

The answer is simple.  Relearn the foot-centric community design of our grandparents generation.

We should be planing future development around the brilliant pedestrian concept of parks, shops, food and communities interconnected by sidewalks and bikeways instead of blueprinting our cities around roads.

Unfortunately our modern day automobile centered towns are ripe for catastrophic collapse because even in the best of pedestrian focused communities the infrastructure for functional bike and foot transportation is woefully inadequate.

For walking to catch on, the facilities to encourage safe, beautiful and efficient pedestrian movement must be built.

Design and build communities correctly around foot and bicycle traffic with efficient mass transit and the future will be amazingly prosperous.

Yet giving lip service through poor design gets us all nowhere quick.  That is where most of our cities are today.

For instance, Palm Coast has built many miles of bikeways and sidewalks.  You would think the area here is a pedestrian dream city.

We have all fooled ourselves into thinking our cities are eco-friendly because we build sidewalks.  Truth is though that most of these sidewalks are constructed as an after thought to roadways.

We will never approach credible sustainability with the thinking - design for automobiles first - and then design for foot traffic and bicycles as an afterthought.

Each day I walk to Public for our daily food.  The entire walk is about three miles give or take.  Every day I chuckle or curse, depending upon my mood, the weather and how heavy the groceries are when I come to this really nice crosswalk across Belle Terre Blvd.

The wide, nice sidewalk ends two meters away from the crosswalk button.

Yes, I am grateful for the button and crosswalk light.  But for a disabled person - or that matter any pedestrian - stepping across huge mounds of fire ants and sliding down a steep hill above a stormwater ditch to reach the cross walk button is more than a little absurd - and certainly sends the wrong message to would-be-pedestrians.

And this one example is just the tip of the huge, unseen by most, sustainability iceberg.

Few but the dedicated pedestrian really understand.

The planning or civil designer and plans reviewer drives a car home.  They have only limited understanding of anything foot traffic centric.  Many think sidewalks are the solution to community sustainability when sidewalks are only a piece to the overall sustainability puzzle.

Walking has opened my eyes to so much.  Give me a city or municipality that really wants to become eco-sustainable from an environmental, economic and social perspective and with pedestrian perspective and the right opportunity, and amazing prosperity could be created.

But few are willing to give up the automobile approach.

And so the cars will burn oil and our cities will sprawl outwards.

Until a petroleum supply event.

And then we will wonder why we didn't take pedestrian design seriously, sooner, while we are sliding into the stormwater ditch after attempting to press the crosswalk button.

Time to Focus on Sustainability

I have learned a lot being on death's doorstep with my dissected aorta.  My transportation is solely by walking now.  In becoming a pedestrian for the past three years I have had my eyes opened to urban green design issues.

I want to share those.

They may come slow as I am truly physically limited.  But I will share as I can.

Sustainability from a disabled person's perspective is wild!

Can't wait to share some of what I've learned walking along the roadside for the past three years.

Living in a world without a car, in a world designed for automobile life, is a trip.  I now do not think a automobile-centric lifestyle is a sustainable approach.

So over the next while - while I am still alive - I want to share some new ideas on how we can create real sustainable, urban green.

Hope you join me.

Living Walls for Sustainable Commercial Design

I was visiting the Town Center in Jacksonville Florida's Southside area this past week when I was impressed with the success of a series of living walls constructed in varying locations throughout the large commercial development.

Living Walls are a great, ecologically friendly architectural addition to any building
The design included several different species of vines and multiple commercially products made specifically to support living wall plants, like the Green Screen free standing system pictured immediately below.
Green Screen trellising system screens a refuse collection area

Unfortunately, the plants used here were not native Florida evergreen vines but rather somewhat aggressive horticultural non-native species.  Substitutions with native species such as coral honeysuckle, Lonicera sempervirens (an evergreen) or Carolina jessamine, Gelsemium sempervirens (another evergreen vine) with beautiful yellow flowers would have added to the biodiversity and provided amazing habitat and beauty.

However I am not knocking the design.  Any vertical green in the urban core has its benefits, from cooling urban heat island effect to cleaning stormwater and air.
Living walls add an interesting architectural twist to design

Living walls create beauty and shade

The important idea is to use and integrate plants in urban settings.  The more vertical green, the more benefits.  Trees also, as we are well aware, can be utilized to create visually interesting architectural points.
Palms as a center piece in the Town Center design

Palms are used to create visual height here along this walkway

On a more limited scale, vertical green systems can be created by the homeowner for a fraction of the cost of more expensive commercial systems and incorporate recycling into the process.

The photo below depicts an example where old chain link fence was used on a vertical wall section below a green roof.  The chain link fencing is quite strong and will provide a trellis system capable of supporting most vines.
Chain link fencing used to create a living wall trellis system

Remember, adding vertical green to the urban core has many ecological benefits.  It is always good to see projects such as Jacksonville's Town Center incorporate vertical use of plants into the architectural and landscape design.

City Greening - A Wonderful Publix Landscape Screen

Most stores on main roadways want maximum exposure.  Driving up and down our city streets we are typically greeted with glaring neon lights, tall concrete structures, multi-colored signs and more of the industrial urban commercialism.

Seldom is the occasion when a major grocery store chain designs a thick screen of native plants between the store and a highway such as A1A her on the east coast of Florida.

A1A Highway & Native & Florida Friendly Landscape Screen, Publix Grocery, Hammock, Florida
A1A is one of the longest, scenic and most historic of highways in Florida and is frequently travelled by many motorists.

Live Oaks, Palms & Cedars, Landscape Screen, Publix Grocery, Hammock, Florida
So it stands to reason Publix would have wanted maximum exposure to automobiles driving past their store in Hammock, Florida.

Instead, even though the store is only a few feet from the edge of A1A's right-of-way, the designers installed a very dense hedge of native shrubs and trees, along with Florida Friendly landscape plants.
Live Oaks, Palms & Cedars, Landscape Screen, Publix Grocery, Hammock, Florida
And you can hardly see the building from the road.

Even though there is a large grocery store and big asphalt parking lot behind the native landscape, the man-made structures are practically invisible to those riding by.

Instead, one is greeted with the beauty of Florida live oaks, palms and cedars.

Unexpectedly, the native plant screen may actually attract more customers by hiding the store.  When I drive by I am aware there is a store there even though I cannot see most of the building.  My curiosity is aroused and I slow to look through native plants at the business.

Maybe Urban Greening actually attracts more customers.

Even so, the native plant hedge provides many benefits to the store and community.  The plants provide habitat for wildlife, sequester carbon, pump oxygen into the air, provide cooling shade, offer beauty and more.

My architect friend, Rob Overly says something to the extent that Urban Greening must start at the doorstep, connecting the roadways with the structures.

Live Oaks, Palms & Cedars, Landscape Screen, Publix Grocery, Hammock, Florida
 Publix has done just that, an excellent job with Urban Greening in the Hammock, Florida location.  To view the landscape and the store take A1A south from Marineland.  The grocery store is a couple miles south of Bings Landing on the east side of A1A.  You'll have to be looking for live oaks, palms and cedars to find the grocery store.
