Green Lab’s vertical farm aquaponic growing system

We now have a fully functioning vertical farm in the Lab employing a tower growing system using aquaponics.

With the delivery of the mint and fish our vertical farm is now fully up and running and we can share with you how and why you should have one too.

We are growing mint in our vertical farm and using an aquaponic system that works with fish, however the basics are fully adaptable to suit your own needs, with the ability to grow a host of various herbs.

Ed who built the system for us explains the basics of how it works –

‘The idea of the vertical wall was that it will fit in a small space and it’s a modular system that can be easily increased in size by adding more wall structures. The design behind it has been left open – I did this partly as an educational piece, it explains itself to the viewer, and can be easily replicated. The system could fit in a school or an office space and would allow you to grow fresh herbs and vegetables.

The system is aquaponic – it’s a circular system – you feed the fish which in turn poo, the bacteria then converts the ammonia in the fish poo into nitrates which are absorbed by the plants and used as nutrients, whilst cleaning the water before returning this to the fish tank.

The fact it’s a modular system means that it can be easily adapted – you can even run the system without fish, turning it into a hydroponic system instead, by adding nutrients to the water instead of using the fish poo.’

HOUSE YOUR OWN VERTICAL FARM

Composting with UCL at Green Lab

We don’t like waste. In fact we are actively trying to eliminate or recycle everything that we grow, farm or produce at Green Lab – whether its eating the food we grow, recycling the cardboard we receive or composting left over food from the lab.

Over the past few weeks Green Lab has been working along side a UCL researcher to develop a programme of research focused predominately on composting and bio-digestion systems.

In late August we participated in an event hosted by UCL at Hackney Wick, Grow: a kitchen & creative space, with a community of London narrow boat users. Exploring the practicalities of composting toilets and the human factors involved in using, emptying and composting.

From late September 2017, we’ll be working alongside a small team of Msc and PhD researchers from University College London – Environmental Engineering, on a project exploring the transformation of ‘humanure’ – yes, that’s the organic matter we produce that is typically mixed with clean drinking water and flushed through a complex piping system to large sewage processing systems – to safe and sustainable products.

Working with the narrow boat community and an on-site system at Green Lab the research project will explore the human factors in designing these systems, and the end use of fertiliser for leafy greens and hydroponic plant growth.

We’ll be using a Kildwick system (generously donated by Colin Ives) at Green Lab and inviting all our early stage startups to participate.

The agricultural composting project will transform mixed organic matter including food, leaves, dead organic mater and human organic media. We’ll be open sourcing all of our findings and naturally sharing the outcome of the project over the coming months.

The project is being lead by Eve MacKinnon, one of the Green Lab team and PhD Researcher in Safe Sanitation Management.

What is composting?

Compost is a key ingredient in organic farming. At the simplest level, the process of composting requires making a heap of wet organic matter known as green waste (leaves, food waste) and waiting for the materials to break down into humus after a period of weeks or months.

To be really inspired read Humanure Handbook by Joseph Jenkins.

Grow at Green Lab

Aquaponics, algae, edible plants, hydroponics, microgreens, insects or mushrooms… take your pick, there is space at Green Lab to grow all of these.

From September 18th we’ll be offering six urban farming residency spaces in the lab for individuals to grow their own food projects. Each resident will have access to a grow bay in Green Lab to farm their own food related project, whether you want install a small scale aquaponics pilot, create an edible plants display or just grow that basil for your pesto.

Green Lab growing bays provide just enough space for small scale projects for individuals, schools or early stage urban agriculture startups. You’ll be able to experiment with growing habitats, lighting and different growing media – they are a blank slate.

Live projects in our growing bays.

Algae

Spirulina growing in 15 litre upcycled water cooler bottles

We only ask you don’t bring any pests or diseased plants into the lab – we’ll help you get started, get growing and learn about urban agriculture. Use of the lab will be free for the first 3 months, after which it will be £30 p/month for the bay.

You’ll need some basics like a grow tray, maybe a light, growing medium or maybe a fish tank – it’s up to you what grow or farm, but we’ll help you get started. You can either bring your own kit or rent from the lab. We offer subsidised rates for students and educational bodies.

If you’d like to become a Green Lab grow resident tell us more about yourself here.

Deadline for applications 12th September with an 18th September start in the Lab.

Green Lab to develop a ‘Green Lung’ #LFA2017 Winner

Green Lab will be playing a key role in a collaborative bid that YOU &ME architecture recently won at the London Festival of Architecture competition. The competition will give the Green Lab team a chance to design a bioremediation ‘Green Lung’ concept beneath the Silvertown flyover, in the Royal Docks area of Newham, east London.

The ‘Green Lung’ will lie at the centre of a ‘Greenline Flyover Testbed’ proposal, exploring how natural sustainable methods can reduce air and water pollution generated from high trafficked flyovers.

Flyover sketch

YOU &ME with 3Space, Green Lab and Mott Macdonald, the practice overcame the competition of 52 other applicants with their proposal “Greenline Flyover Testbed”.
