Fish Poo and LED Lights. Is this the future of food?! | Living Off Grid with Maddie Moate

I have a mission to become more
sustainable across all areas of my life I’m going to look at the changing
production of meat whether I can power my own commutes and what can I do inside
my own home to lower my carbon footprint maybe the future lies in magically lips
summer fruit and fish poo salad whose thoughts it’s January
so it’s winter here in Northern Europe and it’s absolutely freezing which is
the perfect time to talk about strawberries thing is a strawberry
production it requires a warm environment this definitely didn’t grow
out here so where did it grow the benefit of LED lighting is that
researchers like the Sun it can control the light spectrum and develop their own
like recipes to determine which colors the plant’s best respond to red light is
the most efficient photosynthesis and blue light is necessary for good plant
development in the absence of natural light and it’s this recipe of blue and
red which gives us the pink glow here they’ve also added a bit of white light
into the mix but that’s not for the plants it’s to make the working
environment more comfortable for humans it is bright pink in here why why is
everything growing under the lights you can make every combination of light
colors we want the plant is most efficient with red light and also red
light is most efficient to make from electricity so in that case we can go to
a more sustainable growing system and there’s also a little bit of blue light
inside this light spectrum and that also has to do with the clones physiology
because without daylight the plant need a bit of blue light why is this
better than other types of grow lamps because we can focus and we can make
the best spectrum because we can choose with light we want to go have in we can
let the plant grow most efficient so you can choose what the crop needs the main
advantage if we look to sustainability is that LED light needs less energy for
making the same amount of light from which the plant can grow because we have
not a heat production we can we have light and climate more independent of
each other when you grow the plants and the lights like this
do they look or taste any different yeah at this moment we see not we see that
crop reacts sometimes a bit different we see nothing direct influence on the
taste we sometimes see effects on the leafs and the leaf color and we also can
sometimes take an advance on that what do you think of the future of LED lights
yeah from from my opinion LED light will be the future for greener future culture
and also of course for vertical farming LED light will be the main source for
grow lights in greenish water culture we are focusing on measuring more and more
and more because there is really a lot of data in the future yeah we look to
also grow more on data instead of based on growing on the human eye sorry is
this the future of farming or rather other methods out there yet to be
explored here’s a place that’s doing things a
little differently welcome to the world of aquaponics in Brighton UK inside
there are lots of fish and lots of fish poo that apparently are making for some
pretty tasty salad options so this is an aquaponics system yeah quite simply what
does that mean so we can grow any kind of freshwater fish or shellfish so it’s
our culture and hydroponics combined so most plants would also grow but
basically we feed the fish and then the fish waste feeds the plants and the
plants clean the water for the fish so you get that constant cycle of water and
nutrients so the fish who is feeding us balances yeah basically they give off
ammonia and our main waste products and then that gets converted by bacteria
into nitrates which is the nitrogen cycle and then plants take that out the
water that water is going through a filter system yeah it goes through a
biological filter and then goes to the plants and that is turning the ammonia
into nitrate and then that’s feeding the plants at the top of the system yes so
it just keeps going round and round around yeah we know becomes a water all
of the plants that are being used in the system they are completely soilless yeah
there’s no soil in here so the roots the roots are all just hanging directly into
the water some of them hang directly into water
others some are in beds where the water goes up and then soaks the root and then
they drain away again some of them get sprayed with water others did water
literally just runs underneath the roots can you see this working on a much
larger scale it already does commercially on around the world this is
used by large there’s this huge farms acres and acres of ponds with and most
rice in fact is grown in the similar way paddy fields have fish in them all
around the edges and then that wall bloodied through our the only benefits
to growing the plants soilless Lee it several probably one of the most
relevant is the speed of growth because the nutrients are being delivered direct
to the root zone of the plants the plants don’t need to expend so much
energy printing out root growth so it goes into throw new growth for flowering
so yeah the energy is basically going straight into the growth of the plant
rather than so much into the root this is more efficient yeah more efficient
yeah things grow about twice as fast as growing in the ground the plants they’re
getting their food from the nitrates go from the fish but what are you feeding
the fish so different things we painted slap here you can feed them on leftovers
outs of harvesting so you could feed them on the green growth or you can feed
them algae so you picture plants you’re taking what you need any leftover salad
leaves pop it in there it’s just throw it straight in the water things like
trout which require more protein we give them a commercial palace at the moment
but we’re going to research to make fish food more unsustainable because at the
moment that’s the one element that we think is a little bit backing it up
because that’s one thing you’re having to purchase it
yeah we’re purchasing in but it’s also include sea fish and stuff in there we
try to get the most sustainable ones we can okay but we’re going to develop more
feeds which are going to be also will derive nutrients for the plants in a
more commercial way as well mm-hm at the moment the system’s got fish and plants
could we throw anything else in the mix shellfish
what would be the benefit of shellfish they’re filter feeders so they clean the
water and they make a clear crystal there and we haven’t tried it yet B
might go for three powers that’s my freshwater pearl’s I mean you
know they’ve been done before Yeah right in the home from pink strawberries and
fish waste salad to the Center for alternative technology in Wales I’m off
to find out how they’re implementing simple solutions that not only help them
with food growth but also manage their waste chilli and it’s wet but inside we
try it and if apparently these warm and wizardess well they will be this is a
hot bed so it’s a sort of low-tech solution we’ve got a cafe here
on site so the kitchen obviously produces quite a bit of food waste
although they try to keep that minimal but we compost all the waste from the
cafe and this is something that we do in about January mm-hmm and then we put
them away in June and basically we do that to grow all our food plants okay
no annual bedding plants a byproduct of that decomposition is heat that’s and
why is that a good thing the heat just happens naturally anyway as the
composting occurs and so we’re using these cages to try and capture the heat
when we sew our vegetables and our annual flowers they go right on top of
the straw and the heat just naturally percolates through and that means that
you need heat to germinate seeds and you need heat to keep the frost off plants
we’re just using a natural process to create our heat whereas with so we’re
not we’re not using electricity or creating no you’re completely cutting
out the new year this is off grid very low-tech upgrade solution this genuinely
produces enough heat to start that germination basically even in the
coldest winter months yes yes you have to feed it regularly so you have to you
know that the lasagna will grow taller as the months go by I’ve only explored a handful of options
but it seems that when it comes to the future of food production our
sustainable solutions don’t just lie in high-tech research facilities that are
maximizing growth but also in championing simple systems that not only
help us to produce food but also manage and make the most of our waste and to

  1. We could do a lot of stuff at home – if you have the space for that – since you need proper humidity levels which needs proper isolated area to stop mold damage at home.

  2. This is just fascinating. "Green science" as they call it, although sometimes looked down upon, is definitely amazing. And so is Maddie, of course!

  3. Love this new series! Iceland also has a hydroponic tomato farm called Friðheimar and looked very similar to that one in the Netherlands (and served an amazing bloody mary!). Great that these are popping up in different places. Great video! Looking forward to the next!

  4. those farms should not be put all in the same pot. What we feed the plants in the end comes into our bodies. So if chemicals go into the water for the plants, those chemicals end up into our body, liver and all. The same issue comes up when the fish need extra food than the plant leftovers. What is in those pellets that they feed the fish with?

  5. is there research on this "best spectrum of light for plants growth" thing or it just based on observation and experience aka. pseudo-science ?

  6. and i thought using the huge amounts of freely available farmland was more sustainable than producing, powering, maintaining millions of leds. well what do i know

  7. Why do people think that there is only one way to grow sustainable food? Why aren't both the LED farming and aquatic food not seen as good alternative.

  8. Congrats you have discovered a green house with central heating an air… for your next discovery you will tell me about wood burning stoves and mini houses… carry on

  9. was there an error when uploading the video and choosing the title? it really doesn't fit the content at all, since it's more about farming, not really about food storage at home.

  10. You say, “I am in a mission to become more sustainable across all areas of my life.”

    What is the meaning of the word sustainable?

    1. able to be maintained at a certain rate or level."sustainable fusion reactions"
    2. able to be upheld or defended."sustainable definitions of good educational practice"

    I would argue that to be sustainable one has to be able to maintain a certain level of repeatability (daily chores) for everyday things like energy, food, clothing, etc.

    For me sustainable living starts at home. It means generating, growing, and maintaining the sources of energy, food, clothing, etc.

    For instance, generating energy could be done with solar panels or a small tree forest.

    Maintaining energy from solar panels would require keeping the solar panels, inverters, and other electrical devices working on a daily basis. Maintaining a small tree forest would require looking after the trees, and if possible using only fallen trees for heat.

    A different example has to do with food. Preserving food requires techniques and devices not usually seen often in modern life.

    These devices could be used for milling, salting, canning, dehydrating, freeze drying, etc. The techniques used require knowledge and the preparation of food for its consumption at a future day. They preserve food long term, and this implies not using a freezer.

    Moreover, a room is required for shelving the preserved food within a narrow temperature range all year.

    Going off grid is a level of complexity one magnitude above sustainability. It is related to sustainability, but it is much more than this. It implies reliance of oneself for daily necessities.

    Industrialized production of food as you show in this video is a different path disconnected from both of these. It is geared more towards modern life which uses industrial mass production of food.

    The only difference is that as shown in your video it attempts to have a smaller impact on byproducts which are detrimental to the environment.

    But it is more of an I feel good how about how my food was produced rather than I know how to grow this food at home, and I grow this food at home everyday, and I am involved in growing and tending to the food I consume.

    We could have learned more if you slowed down with Petra, and you spent more time explaining the steps of her “Lasagna” rather than fast forwarding the video when she tries to show what she does. It is this attention to detailing the tediousness of sustainable living that means a program with a valuable educational continent or simply a news cast program.

  11. LED lighting Visual Eye Protection Glasses-Mars Hydro runs you about 20 to 30 dollars I love them when working with my plants, i use a 600 Watt led and its a red and blue

  12. Fish poo isn't what feeds an aquaponics system. Fish release ammonia through their gills, and that is what initially starts the process.

  13. Probably so, but it stinks like sour water poured over fresh cut wet grass, so I wouldn't recommend doing this in your house, I know, I tried it, made salads for a week off of just $25 in materials, so I had to move it all outside because the odor overpowered my kitchen.

  14. Fish Poo and LED Lights. Is this the future of food?! | Living Off Grid with Maddie Moate (WARNING: LED LIGHTS CAN BLIND YOU OR CAUSE PERMANENT RETINAL DAMAGE TO YOUR EYES).
    Don't you people use a passive multi-level horizontal oyster shells or fresh water diatomaceous earth granule filled-grid system to allow the ammonia consuming denitrifying bacteria to inhabit them and multiply in countless numbers and convert the ammonia into nitrates that in turn simultaneously feeds the algae that feeds the fishes and feeds the crop plants and medicinal plants all at the same time. By using bioremediation plants you can keep the water also pathogen-free, well oxygenated, non-anaerobic, and clean. WITHOUT USING ANY ELECTRICITY WHATSOEVER! What's wrong with people today anyway? Why can't they keep things as simple and passive as possible or completely in that level so that it is self-correcting and self-regulating and self-protecting and self-regenerating? As for the fishes, use phytoplanktonic fishes and edible herbivorous freshwater fish such as Tawalis sardines, silver carp, grass carp, but tilapia has to be separated for they eat zooplankton also like the small fish frys that are as small as free floating algae but can survive also on phytoplankton alone.

  15. it is not just fish poo that feeds the plants, the fish produce as much nitrogen from their gills as a byproduct of breathing

  16. i heard terpenes and the antioxidants produced is less than from the sun. Also i was wondering how can we replicate altitude? which plays a bigger role, since most of the agriculture tree's and plants Antioxidant density from Coffee, Olives, Grapes and Cocaine =P

  17. biggest misconception about this technique is the fish poo comment… the amonia used to feed the plants overwhelmingly comes from the Fish's gills, not from the poo.

  18. LOL, that is hardly sustainable, but it is a good sales point to "customers" who don't know better. Lmao, "best spectrum," hahahaha.

  19. Sulfur plasma lamps are going to replace LED lamps when enough folks understand them. It took like 20 years to get folks to move from filament incandescent bulbs to LED technology, so it may take another 20 years to get folks to understand microwaves enough to use them with sulfur to make light that is nearly perfectly the same as the sun, and has been shown to be the most salubrious artificial light source for plants.

  20. I made a video of my aquaponics system if you're interested. I'll say one thing. Growing under glass, and with pumps can be expensive…unless….

  21. Sorry to say this system has a very high carbon footprint. All the plastic in tubing plastic sheeting led lights your clothes your wearing the makeup your wearing. Fossil fuels to make glass. The fertilizers shall we go on. I'm sure the greenhouses require no heating.

  22. insects are gonna be future food cause they can easily be bread into large numbers and they dont require a large space to do so. plus their pretty tasty
