Garden overview 

Wanted to provide a little overview of the outdoor experiments that are taking place. 

The raised bed below is a hugel culture experiment.  I laid some rotting wood, then layered in some hay, some leaves,  some compost, some soil, then topped with hay.  

In this raised bed I have planted 3 types of tomatoes, 3 types of radish, and some romaine lettuce. 

The second bed is an in ground bed that I had to get ready in a rush.  I loosened the soil with a pitch fork, but did not turn it.  I then threw on a tarp for 2 weeks to kill the weeds with light deprivation.  I then added some compost and some potting soil. Layered on some hay and started planting. 

In this bed we have radishes, and some lettuces. 

Above, are the potato experiments.  3 containers with a bunch of potato seed spuds.  We just added a new layer of soil, but seems like we’ll have to add more shortly.  Interested to see how high we can go. 

Lastly, we have the chickens.  We tried to build the coop on the cheap, leveraging a second hand bed, some shutters, and a couple of palettes.  In total it cost us about 60 euros for the wire, and some of the longer wood, bolts, and hinges etc.. 

Overall fairly happy with the set up. 


Amateur mistake

In a rush to get my first wave of plants in to the garden before I fly for 3 weeks of work, I forgot/didn’t think to harden my plants.  They’ve been sitting in the greenhouse for most of spring and I put them straight out under the harsh sun. 

As you can tell from the photos, they took a bit of a hammering and I now have several burnt leaves.  Fortunately, I’ve been monitoring them, and the fresh leaves are coming through.  So should be OK.  

Need to remember to harden. 

Chicken coup

It’s the school holidays, so as a family project we have decided to get chickens.  We’ve been researching it for a few weeks, but today we decided to launch our upcycling project to build the house part of the project. 

More photos to come.  But at this stage we’ve got the core framework stood up.  It’s made out of a twin bed frame that I found ditched, 1 pallete, and 3 shutters we got donated by friends. 

Good fun family project. 

Rigged filter

In response the the fact that the roots of my plants were getting a bit mucky as I discussed in this post, I decided I had to change food and rig a temporary filter system. 

To fit the immediate need i simply added plastic pvc pipe stuffed with a fine grain netting material that I found around the house. 

Not a permanent solution but it worked. Immediately, I found the clarity of the water was improved.. 

I even feel like the roots were clearing up after just 1 day… But that’s probably psychosomatic. 

I remember seeing a Murray Hallam video about filters where he compared media filters with gravity filters… His point being that neither is better it’s more the implementation.  Need to check that out before I make my final filter fix. 

Side Experiments

After just pontificating on the importance of focus and production in this post…. I do still want to run some side experiments with the limited goal of increasing my base subject matter expertise, and giving me the ability to go broader with my goals next season.  Off the top of my head those will include:

  • Testing potatoes
  • testing different types of radish, tomatoe, and salad
  • breeding tilapia for sustainability
  • microgreens to supplement salads

In addition to this, My wife and son will be experimenting with a variety of other things.

Learning about Learning

I’ve spent a lot of my recent career solving problems, and thinking about how to go about solving problems – methodology for solving problems.  I have developed a leaning towards lean / agile problem solving which encourages fast experimentation, intellectual honesty (understanding that you don’t know the answer and that you’ll probably get it wrong the first time around) and reflection.  The faster you can perform this loop the faster you learn.

Improving the methodology is all about figuring out how to run experiments, get results, learn : and doing all of that as fast as possible and at scale.

And so I found myself applying this way of thinking to bonsaiponics and i’ve figured that i’m going about this all wrong, or at least I have now reached the point where I need to change the way i’m experimenting.

Up until this point all my learning has been about picking up initial subject matter expertise; does this grow, does this work, what will fish eat, what temperature water, how to hook up system, how to sow plants, how to filter water, nitrogen cycle.

All of this is good solid initial subject matter expertise.  However, if I want to get beyond small experiments I need to start figuring out how to do all of this at scale.  The challenge with nature is that experimentation takes time, plants take time to grow, systems take time to balance, learning in nature in an asynchronous fashion will take a long time. Plus there’s the seasons.  So, i’ve got a window to get a lot of learning done. How can  achieve this as effectively as possible.

The thought process:

So this is how I figured what  had to do….

I reasoned with myself, and recognised that i’m not going to get it all right, there’s so many levels of complication that I still don’t know about, that although i’ve removed several levels of uncertainty…there are still many layers of the onion left.

If I continue in this way i’ll have a broad (horizontal) but shallow knowledge over several things, but not much practical results to show for it.  However, if I can focus, go deep on a limited scope, more vertical than horizontal, I might get some practical results and eventually success.

This reminded me that I had not yet outlined what the success criteria were – what did success look like for me?  In IT talk that would be the V in MVP (Minimal Viable Product) – What is the minimum thing that could happen that would make me feel like this was a success?

What is Success?

For me it was all about production and creation.  At the end of the day, I wanted to produce some food.  I wanted to produce food at a meaningful scale that it could replace my need to buy certain vegetables.

In the past, i’ve planted and had some success with several different types of vegetables, but I never produced enough to make a meaningful indent in to my actual habits. This was the key.  If I could determine what would make me feel successful at the end of the year, then I could use this goal to reduce the scope of learning needed and focus.

The Target:

So, I decided that I was going to focus on 3 core crops which were stables in our house: Salad, Tomatoes, and Radishes.  I then defined the scope of success to mean that I would want to be producing at least, 1 salad, 6 tomatoes (equivalent mid sized), and 20 radishes every week for as along as I could.

There was still a little uncertainty (subject matter expertise) about how long it would take me to get up and running, and exactly how long the crops would produce for, so I did not define how long I had to maintain this target.  However, as a guide I set a duration of “at least one month”:  meaning that at some stage of the year i’d be producing to my target sustainably for 1 whole month (4 consecutive weeks).

Right with that decision made, I immediately started to do some back of the napkin calculations to figure out how i’d get there.

20 radishes a week:

I’m not going to go over the full plan here, but instead go through some higher level examples to demonstrate the thought process and the insights and implications that arose from changing my approach.

So to reach 20 radishes a week, with an assumption of potentially 6 months of grow period in the year left, I would need approximately (20 x (6 x 4.5)) = 540 radishes.  I’d need to plant 20 radishes a week, possibly 25 a week to compensate for those that don’t germinate, I probably don’t want to be planting every week so perhaps i’ll plant 50 radishes every 2 weeks.

Hang, on, where am I going to plant them.  If each radish needs to be planted 3 to 5 cms from each other, in rows 10 to 20 cm apart, then 50 radishes is going to need an 1/8th of a square meter.    Every 2 weeks i’m going to have to plant 50 radishes on 1/8th a square meter, and I should be harvesting that amount too every week.

Seeing as they take 4 to 6 weeks to mature, and can probably stay in the ground for up to 8 weeks, then i’ll need at least 4/8th of a square meter constantly sowed. I’m going to double that because I figure it gives me more flexibility as I can always harvest more if I need, and adjust my sowing rate up to compensate.

This is doable, but only now that i’ve figured out the details of how to micro scale production for this one crop.  It completely changes the experiments that I need to conduct.  And firstly, I need to get a much more aggressive planting schedule.

The Plan:

When I expand this type of thought experiment to Salads and Tomatoes, it becomes clear that my challenge here is not going to be the subject matter expertise of how to grow a good salad, or how to grow a healthy juicy tomato.  The actual challenge is going to be how do I do produce at scale!!??? (in this case scale doesn’t actually mean scale …it’s relative to what I have done before).  And  learn the subject matter expertise along the way to get healthy juicy results.

This now becomes a logistics challenge.  And I do love a good logistics challenge.

This is the game plan at this stage:

  • Radishes, testing several types in outdoor in ground bed.
  • Salads testing 2 types, aquaponics and in ground bed,
  • Tomoatoes testing several types, in aquaponics (flood & drain grow bed) and in raised bed


Full circle learning:

The great news is that this method will also allow me to learn fast because i’ll have a constant flow of germinating plants to mess up and learn with.  Inevitably, this constant sowing strategy is going to provide me with the focus and velocity to go deep and master some focused areas.  Looking forward to it.

Wish I could do the same at work.
