Off-Grid Hydroponics Experiment – The Kratky Method & Floating Raft Hydroponics

Chris Kirkpatrick says:

My wife and I have limited ground space for gardening. the Kratky method
you demonstrated looks to be a great choice for us to expand. Thanks for
sharing. Wish I had watched your video back in 2012, but better late than
never right? Thanks again.

Hello I found your videos about 2 days ago and I found this one VERY
interesting, particularly because of the anaerobic water solution, and an
interest I have in providing a home made chelated iron in hydroponics to
prevent chlorosis. I have a suggestion if I may (please forgive my I am new
to hydroponics)….Here is my idea: an aerobic (oxygenated environment )
will oxidize any ferrous iron (useable to plants) making it ferric iron
(unusable to plants) which is why tossing rusty iron bits (nails etc.) into
the garden never really helps much to thwart chlorosis. This was a problem
for me since I like to provide all my plants needs myself without having to
rely too much on commercial purchases. So after seeing this video I had a
revelation (I hope LOL ). The environment you had these plants in was an
anaerobic water solution which would allow the conversion of iron into a
usable form of iron a non-ferric or rather ferrous iron, since oxygen is
low in the static solution and the oxygen needs of plants are still met. If
you put a fine ready to dissolve iron substance into a water solution and
let it sit for a while to completely dissolve, ( I would suggest a rusty
fine steel wool since its so fine and will dissolve well and maybe even
perhaps pre-boil the water to remove extra oxygen) then you would have a
ferrous iron solution to add to your plants. NOW…. I have read about
things like coffee, green tea, and blueberries etc. being bad for anemic
(low iron) people….why…? because they are iron chelating foods….so
into this ferrous anaerobic water solution you could perhaps add coffee,
filtered (maybe pasteurized) blueberry juice…etc. to chelate this
solution and protect it from any oxidization once introduced to your
non-aerated hydroponics? What are your thoughts?

You have a real knack for this. It is a gift to explain this Kratky Method
in your down to earth way. I feel like you are talking directly to me.
Thanks for all you videos. I have watched most of them, the best ones
twice.

And why did you use regular fertilizer? Can you grow vegetables in this way
using fish water from an aquaponics system? Like a non-electric aquaponics
system?

Mickel Evangelista says:

Where can I get the static nutrient solution. I am new to this and trying
to even learn PH and PPM levels gives me a headache. Is there a simple
solution for the water after I get PH and PPM on point? Unless the alchemy
must be done? Thank you so much any help would really be appreciated.

Hello, I am doing my own experiment with the same method, i planted lettuce
a month ago everything is great except the leaves are soft they look good
but when you touch them they are soft and not crispy hard, the EC level is
around 1.5 PH level is around 7, could somebody please help
Thanks

That box looks to be about 4′ X 4′?

B-rad says:

Hey cool video. I was just wondering if you had to change the water at all
in the static system or did you use the same water for the entire cycle?
Also what else is required? Did you have to add nutrients, or adjust PH at
anytime? Also whats the average ambient temperature of the air in the green
house? Thanks

Would a tomato plant grow like this in 1 gal containers?

Obdulio Cerceno says:

Thanks a lot from Panama. You are doing a lot more for the learners than
many so called Ag.Colleges. We want to learn from a real teacher. My
respect to you!
