taula amiga (friend’s table) diagram

this is the diagram of all the main components of taula amiga farm table.


after the wood structure there are 8 layers:

layer 1 – 1000x4000mm – fabric, any soft material, old cotton sheets or old blankets are perfect materials. this layer is for protecting the thin film of PP plastic (layer2) from touching the non pollished wooden floor.

layer 2 – 1240x4240mm – PP plastic fim 0.2 > 1mm. this should be a food grade plastic. this layer is the main drainage membrane. if punched or not well sealed on the draining holes (10 per table) the water will damage the wood structure of the table.

layer 3 – 150L – drainage material can be small rocks, sand, expanded clay or any inert material. this layer can also be used has a water reservoir for capillarity systems.

layer 4 – 1000x4000mm – TNT fabric, used to prevent the roots from entering the layer 3

layer 5 – 1000x4000mm – wood net. this layer is for prevent any damage on the sub layers like working on the soil with big tools so when someone reaches this layer knows that’s the end of the soil :) the wood has also a secondary function. it will rot slowly producing heat and a home for micro life.

layer 6 – 10000L of coco fiber. coco fiber is an excellent soil structure, it retains moisture and nutrients, the roots have no problem on diving in it and is very light.

layer 7 – 4000L of humus. this is a lot of humus and this is just for one table. we already started the composting systems but we need to go fast or find local sources of good humus.

layer 8 – 1000x4000mm – wood net. this layer is to divide the table by family of vegetables, reinforce the side structure and hold the watering system in position.

local materials: posidonia oceanica


every year in the spring we have algae arriving to the coast. this year we got posidonia fruits to use in taula amiga farm. the fruits are balls of fibrous material that can be added to the compost, has a water reservoir in the draining system or added to soil has structure material.


we also collect tons of plastics.. ;(


III picnic organic


uau!! what a day :) today we had a visit from students of Texas A&M University. we build together   our new model B, a structure to store the tools and give shadow to the composters (has other functionalities like bar :), there was also a workshop for kids about farm fauna and build “houses” for them and like always an amazing paella. please, if you are in barcelona don’t miss this picnics ever ;)

see you next month :p

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 ;)





friendly table design and raw materials

here is the first final design of the farm tables.


this is a farm table designed to be build together with the families that are involved in the social cantine of taula amiga foundation. we think is important that people are involved with the design and building process. you know.. you make it and then it becomes part of you :)

we calculate 60 woods of 2000x100x20 per table. but before we came to this number we went to visit a sawmill. sawmills are not common this days.. like josep fontova said ” familiar sawmills are disappearing all bought by big corporations” so in practice you can not get wood from local resources and when you go to a big store you pay 6x more for the same type of wood and you don’t know where it came from. plus when you go to a sawmill you can ask wood with no treatment, that fits better to our goal of building a healthy container for our food to grow.

since we where here we took some woods to start making the prototype ;)

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 ;)



Scraps-grown fruits n’ vegetables

I’ve recently came across again a habit i neglected for a while. Given its role as a good alternative to composting, besides relatively quick reap, growing food scraps can be fairly inexpensive, ludic and also prevents landfill saturation. There are lots of ordinary edibles we frequently buy that would easily grow on a sunny window sill, mostly, in water, pebbles or soil, as stated here. In order to accomplish that, you might want to know that starting food scraps out in water is often a helpful way to jumpstart a plant, until it establish itself and may be able to be transferred to some other substrate.

Here you go, nearly 1-2 days after i’ve cut this leek section, i would spot it growing again. :)


And voilà:


You would not need more than this that you see on the pic. Juste make sure you keep roots in contact with the water, and nature will do the rest. Five days later i already had a small sprout popping out; you can also see at the background a sprout of avocado (i’ve cut a section so you could see it from a better angle) i had previously caught in a Rio forest . As i stated, there are severall ones you could play along with, as ginger, green onions, lemon grass, potatoes, garlic, and so on.

You must want to notice that in order to grow organic, non-GMO vegetables at home, you will need to start with organic produces.

Good luck reducing your grocery bill ;)
