2nd edition fodder system update

Just launched a kickstarter campaign to raise money to fund scientific research around the nutritional break down of fodder at various stages of growth for our book on Fodder. Please check it out!

2nd edition fodder system update

I recently posted about the new fodder system I built for my buddy.  But as that system was literally just built I had no fodder pictures to show you.  It has now been a full week since that new system has been in use.  And we now have some updates to share.  On the first yield we got 6 pounds of feed from 1 pound of seed.  AWESOME!


This hydroponic fodder system was installed in my buddies spare bathroom in the bath tub.  It is strange to think but that is where a lot of people put their fodder systems.  It sort of makes sense as you would never need to worry about leaks or over flows or occasional splashes.  Here is the system with four days of seed in the trays.  You can see the root mat taking over on the third shelf from the top.


My buddy loves his new fodder maker!


Here is a close up of day 4 growth.  Lots of happy roots.  The seeds were put down a little thick the first time around (1/2” of seeds is all that is needed).


I went back today to see how his system was progressing.  I was happy to see that his day 7 trays were looking amazing.  No slime and no mold.  I did see a couple mold spots in some of his other trays (and noticed his fan was no longer deployed!).  More on that in another post.  Check out this impressive mat.


And for all those that say that light doesn’t have anything to do with fodder I am always amazed to see how when fodder is deprived of light it is often found stretching as hard as it can to get to a light source.  Look at how the back of the tray is exposed but the front is totally hidden.  Granted this could be not as much water, etc.  But water doesn’t dictate the direction the blades of “grass” grow in.


The best part of this entire system though…when I got to their house their young girl says “Mr. Andrew Siemer…would you like to go see our fodder system?”  She speaks amazing well for her age!


I was impressed to see how many seeds had sprouted given that the seeds were layered in so thick!


Here is the system with 7 days worth of seed in it.


While there I added two additional 1/2” branch lines with 1/4” hoses to each tray.  This will get the water to the trays faster to shorten the water cycle.  Little tweaks as we go!




In this video you can see how the combination drain/overflow drain works great.  I am really impressed with this and as it was a fraction of the cost of a commercially available unit I think I might stick with this design.  We do need to get a float valve hooked up to his bath tub faucet though so that the system always gets fresh water.  Then we will drain the tray water directly to the bath tub drain.  Using stale starchy water is one of many things that leads to mold in your fodder.

The verdict?  I am always amazed at how well this stuff grows.  On the first 7 day growth in this system we got some amazing results.

The base weight of a tray is 1.11 pounds.


A tray with the fodder in it is 19 pounds.  That is 18 pounds of fodder.  Or 36 pounds per day!  Awesome.


And as for the conversion rate?  The container we used to measure the dry seed weight with was 2 pounds.


With 4 cups of seed in the container we tip the scales at 3.11 pounds.  About 1 pound for 4 cups of seed.  12 cups of seed in a tray is about 3 pounds of seed.


This works out to roughly a 1:6 ratio.  Or one pound of seed to six pounds of feed.  Not too bad at all.
