This is Why the VeggieWall is Important and Will Have a Lasting Impact on the World: October 21, 2016 10:31

Today, I responed to a message on facebook and I want to share it with you. This is why we are so passionate about the VeggieWall:

LOVE all your questions! Fabulous. Thank you! The plastic we use is the same plastic used in current household plumbing. Yes, some plastics leach, we are super concerned about health and environment so we spent 3 years doing our research. Growing food is so close to our heart. My dad and uncle both passed away from cancer. I believe in people having the choice to eat the healthiest food and knowing what is in it. 

Standard Seeds - Heirloom & Organic

The seeds are gmo free, organic and heirloom varieties... BUT because we want to empower people to grow their own food, we steered away from expensive "seed cartridges" and made it so customers can use ours or buy their own.

We Made The VeggieWall with Recycled & Waste Products

The black VeggieWall is made with 70% recycled plastic. The seeds sprout in coconut pucks, a waste product, instead of rockwool-yuck! Or peat moss. My understanding is we are depleting the bogs of peat, an essential material for that environment, so we steered clear from it. The plant pots are filled with recycled glass, rather than the standard clay, because why take more, when something already exists? Right?

Organic Nutrients So We Don't Lose Out On Taste Or Nutrition

RE hydroponics not tasting as good, it is possible, but that depends on the nutrients you use. We use the ONLY ORGANIC nutrients, not chemically synthesized fertilizers! And the taste is as good as when I had an outdoor organic garden. Much of our produce here in BC is grown hydroponically (you know, those cherry tomatoes in the plastic containers?) Our prototype owners are all about environmentally friendly lifestyles and health: vegetarians, nurses, biologists, vegans, physiotherapists, parents, gardeners, and very athletic outdoor, down to earth people. They helped us get it right and have been testing our prototypes since March of 2014.

Empowering People To Grow Their Own Food is our Mission

The goal of Green Thumb Technology is to empower people to grow food. It is for people that either do not have the time, know-how, or space. I live in a 500 sq foot apartment with no patio or outdoor space, Matt lives in a basement suite. We also live in dark, cold Canada (haha, this message was to a woman in sunny California) with a short growing season. It is also great for areas with water restrictions, as the recirculating water, uses 2/3rds less water than an outdoor garden. I could go on, as I am SO passionate about this and putting food back in the hands of the people... Feel free to contact me: Again, thank you so much for your comments and interest. Sincerely, Jen Jen McGuinnessand Matthew Mei"

We need your help to make our dream come true and launch the VeggieWall. Please support our cause on Kickstarter:


Have You Felt The Squeeze at the Grocery Store? October 06, 2016 07:36

We have! Food prices continue to climb due to the impacts of climate change. For example, a case of lemons has gone up $20 US this year to $50 from $30 last year (AgPro Journal). The US Drought Mitigation Center said 2015 was the driest winter in the Sierras. What's that quote about insanity, doing the same thing over and over again, and expecting different results? It is time for change.

The Old Ways of Growing Food Are Not Working Anymore - We Have a Solution


California Drought - Irrigation Taps Turned Off

According to the BC Food Systems Network 67% of Canada's food is imported from the US and over half of it comes from California. Many states, Alabama, Georgia, Washington, Oregon, Idaho are also experiencing drought and crop failures. 

Spraying Crops with Pesticides - If It's Safe to Eat, Why do These Workers Have Hazmat Suits On?

"Worldwide, more than 5 billion pounds of pesticides are sprayed onto crops each year, and more than 75 percent of the US population has detectable levels of organophosphates (OPs), which are among the most commonly used insecticides on American farms" (Mercola). Brain damage, coma, rashes, cancer, headaches, Parkinson's disease, the list goes on. Huh? What?! Organophosphate pesticides, first developed as a nerve gas in World War II, are the most widely used insecticides in the world. Remember that comment about insanity?

Control Over What I Eat - Urban Food Solution


The more food we grow, the greater our ability to reduce the impacts of industrial agriculture on the planet.


Rachel Carson linked pesticides to cancer in 1962 and as a biologist, studied the effects of pesticides on the surrounding environment: birds, water ways, insects, fish, etc. And yet, here we are in 2016. This angers me, but we all know the problems with our food systems, so let's talk solutions!


Organic, local farms, and growing your own. People across North America are getting creative and replacing concrete and grass with veggies: backyard, balcony, sidewalk, community plot, schools, rooftops -  I Love it! I used to live in a very shady town home and now I am in an apartment without a balcony, but I still wanted to grow my own food, so we created the VeggieWall. Who is the VeggieWall for?

  • It's great for people that don't have space or time for a garden
  • It's great for people who do have a garden but want to keep growing throughout the winter
  • It's great for people that do not know how to garden
  • It's great for areas experiencing drought because it recirculates the water, using 2/3rd less water than outdoor gardening
  • It's great for anyone that isn't already growing their own food or lives in northern climates where we have a short growing season

The VeggieWall - the Urban Food Solution

The VeggieWall will only be made possible with your help. Please check out our Kickstarter Campaign and help us grow our business and make our dream of providing people with an alternative that is healthy for them and the planet! 

Thank you for reading our blog. This is part two or a three part series on why it's beneficial to grow our own food. Check out part one: your health. 

How do we stack up against the competition? October 01, 2016 09:13

Thank you for reading our blog. We are 4 days away from launching on Kickstarter, October 4th, 2016 8 a.m. PST. After three years of research, development, and testing  it was surreal submitting our campaign to Kickstarter a few days ago. 

When we began researching and sketching ideas there were four indoor gardens on the mainstream market, and new concepts coming out regularly. Throughout the process of creating the VeggieWall, Matt and I have watched many more indoor gardens get developed. Each time I searched the internet for new indoor gardens, I took a sigh of relief that each new product was another counter-top garden or another large cabinet-sized garden, using pre-existing hydroponic systems. Clearly there is a demand for indoor gardens, but who has the counter or floor space? It was important to us to have a indoor garden that added to the ambiance of your home, so we invented a new hydroponic system. 

The VeggieWall

We invented the Vertical Nutrient Cascade Technology

  • Vertical. 24 plants in 2.5 square feet.
  • Easy to use and gives you success with growing food even if you do not have the know-how. Our technology is your green thumb.
  • Fits seamlessly in your living space. Stylish, slim, and artistic.
  • Modular
  • Automated LED lights for growing plants year-round.
  • Automated self-watering pump
  • Wifi micro-controller connects to your smart device for growing tips. 





Launching on Kickstarter Oct 4th 2016. Please support us and help us realize our dream of providing healthy affordable food for people.

Thank you for reading.

The Story Behind How We Invented the VeggieWall September 26, 2016 10:05

Year 1 - July 2013

It began 3 years ago while I was researching how to make my balcony garden more vertical. I came across vertical living walls. Living walls are vertical gardens, most often using hydroponics - a nutrient water instead of soil. The living walls grow typical house plants. This got me thinking, can it be done with veggies?

More research led to discovering greenhouses grow food hydroponically and so does NASA. I called up my friend Matt and told him my idea.We started with sketches and bounced ideas back and forth.

Here's what happened next:

  • Simon Fraser University Business Accelerator
  • Meeting with an engineering firm
  • Discussing with the National Research Council of Canada what was new & innovative about our idea. And what IS New & Innovative about the VeggieWall? All other indoor gardens use pre-exsiting hydroponic water delivery systems. Vertical is rarely used because it involves drippers or sprayers, which clog & plants die quickly without water. All other indoor gardens are big, clunky counter-top, tub & tower, or cabinet-style systems. Who has room in their home for that?! They also grow very little for how large they are.
  • We set out to invent a new vertical system that would not clog. The VeggieWall grows the most food in the smallest Sq ft and it it's modular. That's what's new and innovative! 

  • Over the past 3 years, there has been a big influx in indoor hydroponic gardens. They are all counter-top units or bigger. For the same price, and often cheaper, the VeggieWall is still the only vertical garden! 

Fast forward to March 2014

We made the 1st prototypes in Matt's backyard and sold them to some willing tester candidates. We grew food indoors! Of course there were a lot of problems, it was a prototype after all! 


The biggest problem was water flow. We tried using a drip and then a spray irrigation system. Both clog. Plants would die overnight or when we were at work, when they were cut off from water.

Summer 2014

So we hit the drawing board. Lots of sketches and over a dozen different prototypes, we tried to find a way to create a high-flow vertical water system. Current hydroponics use horizontal systems that allow for high-water flow to avoid the clogging issues of drippers and sprayers. We had many unsuccessful attempts but we were learning a lot! 

The Breakthrough! Fall 2014

One day Jen asked herself, "how does water flow in nature?" She had her answer right away and set out to test it. It worked! We hired a designer to help us create a 3D print and test it further. 


Success with the design for the 3D prototype was short lived. We discovered that it was going to be difficult to manufacture. We needed to keep the water flow the same but change the way it was made. 





Summer & Fall 2015 - the Next Breakthrough

More prototyping. We were getting closer. Matt's handy skills from years in construction and all forms of art really paid off. 

  The prototype family, Matt & I made by hand in his  backyard. Sophie, Matt's wife is an architect and  helped us draft up AutoCAD files, which we then took  to a manufacturer in Vancouver BC. The VeggieWalls  were made by hand and we sold these to early adopters. 

 Again, there were issues with the design, but we were  getting close. Real close! Our prototype owners in the  Yukon, Whistler and Squamish were growing fresh  food in their homes throughout the winter! 

  Whistler - bursting with lettuce, tomatoes, and cilantro - March 2016!


LED grow lights are very expensive. Using a pre-existing product was going to cost customers an additional $200, making the VeggieWall cost $550. It is really important to us to keep the cost as low as possible while providing a high quality product.

We met with an LED grow light specialist in Vancouver and discussed paying them for a consultation fee to help us source the LED chips and parts needed. The companies quote for their consultation, $100,000. Ya, that was a big "No!"

But we carried on. I researched LED lights. It took me about a month, but I was getting better at navigating the manufacturing world. I figured out what we needed and sourced a manufacturer!

September 2015 - Funding from the National Research Council of Canada (NRCC)

With funding from the NRCC we hired a design team from Emily Carr Art & Design University. Together, meeting every Tuesday morning, we spent the next 5 months finalizing the design and manufacturing process. This was a really rich experience for Matt & I to get to work with this team. 

Lead Up to Kickstarter March-September 2016

The past 6 months has entailed meeting with local manufactures, receiving their quotes for production, choosing one, making our moulds and conducting a test run of the VegiieWall, which you see in our pictures now. We have sourced our LED lights, tested them, as well as all other components. The rest has been photo shoots, filming our kickstarter video, and filing our patent. 

We are ready to bring the VeggieWall to you! We are really excited to see what you will grow in your homes, schools, offices, and cafes.

Help support our campaign Oct 4th and realize our dream of empowering people to grow their own food!


Growing Food: For Better Health, Environment & Society September 15, 2016 14:08

Grow my own food? Why bother?

Personally for me, I have many reasons. I can break them into 3 categories: my health, it's better for the environment, and social contribution. 


Personal Health:

Jen: Contemplation in the Bugaboo Mountains

I have experienced 2 close family members pass away from cancer. My Dad battled cancer for 7 years, in that time he changed his diet and experienced a quality 6 years before succumbing to the disease. I know a lot of you can relate. Eating healthy reduces our risk of diseases. Yes, of course, we are all going to go sometime... BUT, I am not just eating well to prevent disease, it goes well beyond that for me! It's more about the present. I truly believe in, and feel blessed about, being active, being in nature, and living a full life! Nourishing my body with good food allows me to have the mental, emotional and physical outlook to experience the best of life.

The BEST food, is food you GROW YOURSELF. Why? Plants like, leafy greens, loose their nutrients once they have been picked. For example, leafy greens can loose 50-90% of their vitamin C in 24-48 hours. The longer plants have to be shipped (I'm thinking boxed lettuce from California to BC), sit in the grocery store and in your fridge, the less nutritious value you get from them. We think we are doing something good, by eating a salad, but we are only getting a fraction of its benefits. 

Picking fresh greens from the VeggieWall

Growing fresh means I can pick it and use it the same day, maintaining 100% of the foods essential vitamins and minerals! And WOW! Does it ever taste better!

Of course there are other health reasons that are important to me, namely when I grow my own food, I know what's in it. This is often the same reason I buy from local farmers. The organic industry does allow for certain pesticides to be used on "organic" vegetables. Did you know there are pesticides that are banned in Europe that are used in the US? 

Lastly, growing your own food opens a whole new world of varieties of produce you can't find anywhere in the grocery stores. The heirloom and organic varieties that are available when you grow from seed are outstanding in flavour, look, and nutritious benefits. 

Next blog, I will talk about the benefits to the environment in growing your own food. Until then, eat something fresh & get outside! Thank you for reading.

Oh the Weather Outside is Frightful, but the Veggies Growing Inside Are Delightful! Let it snow, let it snow, let it snow! December 17, 2015 16:35

Kickstarter Launch Fall, 2016

Happy Holidays from Green Thumb Technology! In this blog you will learn how we deigned the VeggieWall. 

December 17, 2015 - Snowing in Squamish: Lemon Cucumbers Blossoming & Mizuna (mustard green) Flourishing Inside in the VeggieWall

A year ago, last winter, we were growing veggies in our homes with PVC pipe, Martha Stewart wall file-folders, and pretty much anything else we could make: gutters, PVC pond liner, plywood, cardboard, yogurt containers, and buckets. You name it we tried it!

In the spring of 2015 we nailed down our design, hand-made our first VeggieWalls and sold them. Today, with funding from the National Research Council of Canada, we have 5 designers from Emily Carr University working with us to complete our product for commercial manufacturing in 2016! What is the design challenge? Well there are lots, but here are the ones we thought you would find the most interesting:

  • The initial problem was water flow. Go with a pre-existing vertical drip system and endure constant clogging and plants dying. Increase the water flow, and have it spill out. That's why current hydroponic systems are horizontal, and so big and clunky. Neither, of course, was acceptable for us. We worked at it until we figured it out! Now our breakthrough Vertical Nutrient Cascade Technology is the 1st vertical high-flowing system! It's also the 1st modular, wall mounted Vegetable wall, and it has a slim artistic design! 
  • Cost, cost, cost. The more it costs us to make, the more it costs you, our customer. Our goal is to keep the VeggieWall affordable for the average NA household. That is no easy task! Although, we have the design, how we actually manufacture and assemble it can greatly reduce or increase the cost. We have got it figured out!
  • LED Lights - We were quoted $100,000 in consulting fees, which takes us back to cost. With a lot of research and a little patience, we have figured out an affordable LED grow light option too!
  • Sustainable: Our VeggieWall is about 80% Recycled & Waste Products. Ya cool! We make the VeggieWall with recycled plastic, our seeds are in coconut husks (waste product), and the plants grow in recycled glass.

Yesterday we met with an inspiring group of students from Howe Sound Secondary school and shared Green Thumb Technology's vision to change the world for the better! They will be the 2nd school Green Thumb will be donating a VeggieWall to. 

Kickstarter Launch Fall, 2016. Please help us by sharing our story :)

Matt - walking in the snow today. Getting ready to film. Meanwhile, buds on sweet bell peppers are enjoying the VeggieWall and the warmth from the fire.

Why is it so important to supplement our diet with food we grow ourselves? November 02, 2015 20:24

Did you know that Leafy Greens at room temperature lose 50-89% of their Vitamin C within 24-48 hours from harvest? All fruits & vegetables lose their essential nutrients once they have been picked, some more rapidly than others.

The healthiest, most nutrient rich food you can eat is food from your garden to your plate. Vitamin C is an antioxidant. Antioxidants help prevent cancer, heart disease and arthritis. There is no conclusive evidence that taking vitamin C supplements will help or prevent any of these conditions (University of Maryland, Medical Center). Like many of you, I have had family members pass away from cancer & heart disease, so this is important to our health! 

Our food production systems have gone in the wrong direction. Soil degradation, drought, and toxic chemicals (did you know the US is approved for 82 pesticides that are not approved in Europe?), and deforestation, are all effects of trying to feed 7 billion people with mass agriculture. The average North American meal travels 2,400 Km to reach your dinner plate. Not only does that put a lot of Green Houses Gases in the air, the plant based foods have lost a lot of their value before you even buy them! 

According to the UN we will not be able to feed the world population in 2050 using the growing methods we use today.

California Drought Impacts on Farming

So We Are Changing the Way We Grow Food!

The trend of eating local has put the control of food closer to the people. But only growing your own gives you complete control and assurance that you are eating food packed with nutrients... that is if your soil is of the best quality. As a gardener, and green thumb, I know there is so much that goes into growing food! Did you know that plants that receive lower levels of sunlight, have lower levels of Vitamin C? 

Green Thumb Technology is passionate about providing the ability for anyone to grow their own food in the comfort of your home. Our technology is your Green Thumb, so you don't need to have the time, know-how, or space to grow your own food!

We use organic nutrients, all the same essential nutrients & minerals found in the best organic soil. LED grow lights provide the optimal sunlight spectrum for growth all year-round. Cherry Tomatoes in January anyone? YES please!

And when we say anyone, we mean it! We have worked so hard to keep the cost/unit as low as possible, and we have begun our commitment of donating VeggieWalls. Our goal is to make a profit from those who can afford to buy, so we can donate VeggieWalls to individuals, families, and even entire communities that cannot afford it! Imagine a Food Bank Wall covered in fresh, organic food. Rather than taking home processed, canned goods, people can nourish their bodies with the best food!

We are excited about where Green Thumb Technology is going and how we can help people live healthy, happy lives by putting the best food in their bodies!

Jen's Bio & the Values that drive Green Thumb Technology July 28, 2015 17:38

Meet Jen - I have been asked quite a bit if I am an engineer or industrial designer, no I am not. In fact, I have spent the past 14 years guiding trips by ocean kayak, backpack, ski, and as a mountain rescue technician. So how did Green Thumb Technology come to be? 

When Jen is not working, you will find her in the mountains or on the ocean with friends & her avalanche rescue dog, Neve.

I have always wanted to run my own business, and I wanted it to be something that contributed to taking care of our environment and contribute to society. I was studying an Interdisciplinary Masters degree at Royal Roads University, but felt too much time was spent on theories, problems and in general thinking too small. I wanted to talk solutions and do something!

In July 2013 I was researching how to make my patio garden more vertical.... the pots were taking over the deck and there was nowhere to sit! That's when I came across living walls. Plants growing vertically on a wall. They are fed nutrient water instead of growing in soil and are living wall-tapestries. I thought that was really cool, and wondered who is growing food this way? 

Imagine being able to grow organic food inside your home year-round. No more shipping food from around the globe, no pesticides, no greenhouse gases. Totally organic, fresh & local - all the time!

Peppers from Mexico. I pulled these out of the grocery bag and they are already rotten! Peppers are rich in Vitamin C, but if they are not organic they are heavily sprayed with pesticides.

l live under the Squamish Chief, it's a beautiful 1800 foot granite monolith, with the Stawamus river underneath. In the winter the sun doesn’t crest the top of the Chief. Its dark, its cold, its wet, but inside my townhouse it is 15-25 degrees Celsius, the perfect climate for growing food! Last winter I grew bell peppers, tomatoes, herbs, and greens on my dining room wall. Here’s a picture from January of tomatoes, peppers, and oregano growing inside:


I have always made decisions based on my happiness, health & lifestyle...

I have traveled quite a bit. I have seen poverty, suffering, and cultures that place the greatest importance on relationships and community. I grew up in a single-mother home. My brother & I had a great childhood, but there were a few times when our cupboards and fridge were bare. A few family members have had cancer, 2 have passed away from it.

These have all been formative experiences that drive the values and vision of Green Thumb Technology. I believe, everyone deserves access to Organic food. Not the cheap, processed, chemical laden, and GMO foods - But REAL Food. Fresh, local, and organic.

That's why we sell Veggie-Walls to people who can afford them, and donate them to people who cannot!

I believe if we eat well, we feel better. Food is community. And with healthy people and communities we can make significant positive changes for our environment and society. 

Thank you for reading my autobiography. I hope to hear from you and look forward to hearing your stories about what you are growing with your Veggie-Wall!
