II picnic organic

this is the second, expect one every month from now until the end of the summer :)

the picnic organic gathering organized by m.u.l.a and friends is where everything fits together. a bit like music where all the different instruments contribute to a common track.

in quirhort we have different teams that every 2 days feeds the composters and give a good turn to all. the composters are feed with neighbors organic waste and vegetables that this team gets from local shops. but before this organic waste goes to the composters, we separate what’s suitable to eat/cook/share and just then what’s left goes to hermetia illucens :)
part of this food gets frozen and is with this food that we make this amazing paellas for everyone that comes by this days and eat with us.


today we installed a automatic watering system in one farm container

see you next month ;)

do it together

today we started the building process. we’ll first prepare the composters and then we’ll start the first farm table :)

all workshops need working tables.. we improvised a bit ;)





new composters arrive

today the tarragona city council brought to us 4 trash containers that are broken. they are perfect for us, we cover all the bottom holes, build a wood base that holds the trash and drains the liquids, build a structure that elevates the container so we can put a tube for leaching collection and turn the composter more easily. here a link to our wikiIMG_6798 IMG_6800 IMG_6801

day one: prepare composters

today is our first day of a series of workshops.

we plan building this farm together and with so many things to build and many more to learn we setup the goals for this next months: building a urban composting system, build the first 8 tables for the families and 2 more if there are neighbours interested in growing their vegetables :) in between we’ll learn how to grow food. we’ll meet every friday from now until the end of april. come join us if you are around ;)

from A to B

today is our last day in hort del circ. the city council wants to dig the roman ruins that are under the farm so we must leave. but one finish and another starts :p we are taking all the soil and some farm structures to taula amiga’s farm.

l’hort taula amiga

general view 1

this is a project that we have been cooking for some time now. we manage to involve 3 institutions and give some meaning to this farm. the idea is to engage neighbors and users from taula amiga social cantina to produce their own vegetables. a farm has a tool just like we see it :p

the city council gave the allotment. no water, no electricity, no direct sun. design and biology challenges are all there :)

horticulture school of reus will give us the local approach. local seeds, small workshops of calendars and farm management, organic farm procedures and will keep an “eye” over the new year.

and taula amiga: we first meet fundacio formacio i treball through another workshop in barcelona. we needed washing machines, they didn’t have but in between we made a visit to their headquarters and we meet their social cantina project called taula amiga (friendliest table. in catalan sounds better:) every one in this cantina is involved in some kind of integration/formation work and the farm is meant to them. we will start with 10 families and some neighbors the design and the construction but first and until the spring of 2016 we are having horticulture classes and start a community composting.

espai quiro farm containers II


uau, great day today!! we took apart pallets, cut some of them on strategic places, add screws , prepare some wood wheels and you get yourself a nice farm container :) all made with recovered materials from the surroundings.

next steppes will be building some more (will be dependent of the local-analog-crowfunding-campain that we are setting up:) and then apply our automatic watering system also made with urban trash ;)

will keep you posted :p IMG_6084 IMG_6086 IMG_6088

espai quiro farm containers I

today we meet to start build the farm containers. this is our lunch on saturday :)


we started early preparing the base of the farm container.


and then move along cuting woods, take apart pallets and making weels. here you find a link of the farm container in our wiki.


IMG_6078first prototype finished. see you tomorrow ;)

composting at espai quiro

the idea is to start a group of urban composting, you know, we need to start making food for the vegetables :p

to start we’ll try 2 diferrent systems: a variation of berkley’s hotcomposting method and my friends Hermetia illucens 

for the hermetia illucens we will build composters from some old trash cans the the city council kindly gave to us. we’ll collect the leachate on a 1,5L pet bottle.

here some photos of the firsts gatherings.

espai quirò

back in april we made an open call in hangar to give a workshop. it did not go through cause we didn’t had enough people, but among the people who contact us was M.U.L.A. a beautiful collective project of house sitting, a DIT project made with both human and materials from the surroundings where old buildings are recovered by the people and supported by the proprietaries. we and MULA started to talk of making a workshop on the upper town and for us is great to have a project in this part of barcelona. MULA with other local entities are promoting the use of a vacant allotment where a old clinic (quirò) was taken down. they have an agreement with the city council for 2 years. it’s 3000m2 and more or less half will be available for urban farming. since we can not use the soil we’ll built farm structures with wheels for urban mobility :) apart of building the essential structures: shadow, composers, farm structures, watering systems, a kitchen :) we’ll try to go further this time and one of the tools we will try to implement is the local cartography of raw materials to build soil. we need to select composter systems and recipes to start mapping the leftovers of restaurants, citizens and other specific ingredient to then make the schedule of collecting. some tricks we can made like for example make a dropbox only to egg shells or sea shells. you know.. not only the local gastronomy is deeply connected with different vegetables for different seasons, the compost you can make in a city is also connected like this: here people eat “tortillas” and sea food and this are excellent providers of minerals.

we are starting a local-analog-crowdfunding to this project. check here the poster duna made. we have 3 kinds of farm structures, a starting party with food included and other surprises for the supporters :p you can support this project on selected places, like pepi’s bar, where she will explain to you and in person all the great things about this initiative and if you have time you can also know a little bit more about the neighbor and the surrondings supported by honest food cooked by pepi’s husband and the espai quiro blog webmaster, antonio.

the first design-together starts next sunday. we’ll meet in espai quirò around 11h. see you there ;)

planta’t 2015

you know that we have been researching about urban soil for a while and one of the tools we have worked with is chromatography. next 7 june at the botanical garden of barcelona we will give  workshops with 2 variants of this separation technique: photo chromatography for soil samples and paper chromatography for leaves pigments separation. check the program here there are plenty of great activities ;)

fescamp 2015

this year we were invited by ciclica to give 2 workshops in fescamp. today I came with xavi to give our last workshop. have you ever been here? fescamp is a annual gathering that trough collaborative artistic practices promotes a critical reflection about the city of Sant Cugat del Vallès with focus on environment and sustainability.

we had a great workshop. many people interested in watering systems and e-trash recovering.

hope to see you there next year ;)




madrid medialab_prado workshop

yeah! this time you must run!! in 4 days we’ll be traveling to madrid to give a 6 day workshop and build together the medialab prado farms :) this workshop is free for you there are still a couple of available places!! run run to here :)


barcelona workshop open call and back home :)

has been 6 years and we now return to after studying 15 different cities, different food, different tools and different trash. it’s good to be back home with a workshop program that’s the most comprehensive we’ve done so far. we also have other plans for the other days of the week so if you want to build together your next low budget automated food table just join us if you want to collaborate on the space building or on urban composting you are more then welcome ;)



iaac 2015

we’ve good news!! from january to june the SUFj project will development new collaborative works and social happenings for iaac’s rooftop garden. me, wen, mar and sebas will give more news soon but if you wanna join us you are more then welcome. we meet every tuesday from 10h30 > 17h~20h

Collaborators for Mexico!

This week the group of people that are going to be helping us develop our Soil, Food and the City project at the Medialab Prado workshop in Veracruz was chosen.

You can check out who is heading to Mexico for all the different projects here.

We can’t wait to meet this group and start sharing ideas!

We’re also going to start trying out different protocols to have an idea of what works and what doesn’t before we arrive to the lab!

Laboratorio Iberoamericano de Innovación Ciudadana.

Good news this week; Our project “Soil, Food and the City” (“Suelo, Ciudad y Alimento“) was one of ten projects selected from around the world to be developed at the MediaLab Prado Citizen Innovation workshop to be held in Veracruz, Mexico, in November.

The objective of this project is to create a low-cost tool that we can use to evaluate the quality of soil in an urban setting. With this tool we’ll be able to map empty lots in the city which have the potential to be used to grow food, with the end goal of achieving food sovereignty and security.

To create this global picture of urban soil quality we’ll conduct various tests. These tests would be conventially divided into three ‘boxes’ or subsets of tests, each with its peculiarities and advantages. The kits consist of affordable and sufficiently qualitative tests for the assessment of soil properties in urban and peri-urban sites. The complementary nature of each test will help citizens and scientists to gain an overall understanding of soil health and processes.

So if you think you’d be interesting in helping us develop this project, or to learn more about the workshops as a whole check out the collaborators page here.

2014 beijing design week

recently the refarm group of barcelona was invited to participate on the beijing design week by the barcelona 2014 BJDW guest city program. we are going to make a showcase of our tools for urban farmers and make several DIY and DIT workshops.

the idea is to implement, on an existing house, the cicles of nutrients, water and energy along with farm structures and electronic tools that allow in-house food production. three of our members (hernani, emilson and guilherme, will fly from 15 september to 5 of octuber.

stay tunned, next week we’ll open a call for colaborators to help us on the building process of this exhibition.

more news soon, but if you are on the area please join us, we need you ;)

mediaLab Prado: Laboratorio Iberoamericano de Innovación Ciudadana

This week we’ve sent off a project that we hope will be included in the MediaLab Prado “citizen innovation” workshops that will be held in late November in Veracruz, Mexico.

Our project relates to soil health in urban and peri-urban areas and how ordinary citizens around the world can learn more about their soil, its processes, what it contains, and even how to improve it using open source tools. Click the pic below to read more about the workshop.

We’ll know if we will be on our way to Mexico in the first week of September, so until then, fingers crossed as we tend to the veggie garden!



Citizen science?

Currently there is a huge divide between the “scientific” world and the general public. The responsibility to protect and preserve our natural environment as well as to maintain our food security has been placed in the hands of too few people. And unfortunately it is way to common for these people to have political pressures to act in one way or another, and not always in the best interest of the general public. These figures too often bow down to big businesses and money. You only have to look at how many corruption cases are being held around the world involving political figures or people meant to be representing “our” best interests.

So what about citizen science? This is something that is meant to bridge the gap between politicians, those guys in white labcoats sitting behind a microscope, and you, a citizen of the world. Through citizen science, we can have millions of individuals, trained to observe and record, collecting data from all over the globe. The information gained through citizens world wide looking at what is happening in their backyard creates “study sites” in many more places than would ever be possible by just scientists alone. And it connects us back into a system in which we NEED to take more responsibility.

Work at IAAC’s rooftop

Currently is being kept an automatic irrigation system on IAAC’s rooftop. It’s a basic version that stores data in the Arduino, how often and how much time it was on. The basic components are: a switch by pressure, an Arduino and a valve to water control.

The next step will be build one that also measure flow, temperature and humidity, and maybe use a memory card adapter, if the data isn’t monitored in real-time.

The code is ready and the system is in construction, just missing a few pieces. It will be ready soon.

This system will be in the garden that is being constructed there too, big part of the structure that will keep the garden is ready. We were (and still are) working hard, cutting and fitting pieces of wood to be the best possible.

FAB10 Experience

This event happened in Barcelona, one of the bigger event that I ever participate, where I could learn and share a lot of information, meet some people, good contacts, specially from other FABLABs, including  one from Belém (Brasil), is where I live there. Also, I participated of some interesting workshops, one about construction of a 3D printer with a lot of materials from eletronic waste and other about Arduino, “SmartCItizen” and “Hands on Wireless Sensor Network”.

The Refarmthecity also has presented a workshop about the automatic irrigation system, the objective was tell people how to make one, learn how to build themselves, what is important about it, equipments, components and the cost (lowcost). Besides some problems with the FAB 10 the objective was accomplished, we presented the idea and made people get interested about it.

– iaac labour sunny days

Looking foward to seeing the whole structure allover together!


After conceiving the wooden structure that will support the roof garden with the archictectural help :P of Nestor and Xavi, we passed to the action.



We already have it in a more advanced state – things are evolving quite well… next step: chosing the species that will be growing in the raised garden beds :)
