title: "Keep a lab notebook"
tags:
- opinion
---
I have been "[farming](https://twitter.com/croyfamilyfarms)" for a few years
now and as the beginning of the 2017 season in northern California approaches,
I wanted to share some advice to consider, regardless of whether you're a
gardener or not.
**Always keep a lab notebook**
For just about any hobby project I have found a lab notebook can be invaluable.
What I consider a "lab notebook" is just a simple spiral notebook, with dated
log entries, on what I have done, observed, etc.
Currently I have two different hobby lab notebooks floating around, one is my
"Farm Book" wherein I will log:
* What has been planted in which sector
* When I planted seeds, starters, etc
* When seeds germinated.
* Notable conditions. A particularly hot week, wet days, etc.
* When plants begin to fruit, and the quantities.
Over the seasons, I can refer back to my Farm Book and improve how, where, and
when I plant. Perhaps more importantly however, I can refer back to the Farm
Book after I have been "out" for a while, whether traveling or just not paying
attention, to figure out what projects/tasks I left off with.
For my [other hobby
project](https://www.flickr.com/photos/agentdero/29706573822/), my lab notebook
has been even more valuable. Not only acting as a truck-repair-log but also
storing data on diagnostics performed at varying intervals. In the case of my
old truck, without a running log of what experiments and diagnostics I have
performed, repairing it would be a futile effort.
I was first introduced to this practice by [Bluthe
Rocher](https://twitter.com/blithe) in her talk [The Scientific Method of
Troubleshooting](https://www.youtube.com/watch?v=h9YZXuUjyOs) in the context of
software development and troubleshooting. Of course you can, and should, use
something approximating a lab notebook during the course of building software.
> **Sidenote**: Using Git commits and a `NOTES.adoc` in a repository is a great
> way to accomplish this. Many times, on my own projects, I will commit an
> experiment that failed with a commit message explaining what didn't work, and
> then revert that commit.
While it's easy to understand the value of additional rigor in software
development, I urge you to consider keeping a lab notebook for any other hobby
or side-project of any importance to you.
Inevitably, you'll find yourself staring at your project on a Saturday morning
wondering "what the hell was I doing here?"
Keep a lab notebook, and give yourself the answer.

Somewhere along the line, safety became a crucial part of my decision-making
process. I always wear my bike helmet. I put on my protective safety glasses
when wielding an axe or doing something which might splinter or launch debris.
In my tool closet I have a big bag of ear plugs which I put in whenever working
with a power tool bigger than my cordless drill. When riding a motorcycle I
always wear my full-face helmet, armored jacket, and sturdy gloves. And of
course, when I am driving a car, I **always** check my blind spots.
Somewhere along the line, I came to appreciate that: **Nobody is looking out
for your safety but you.**
I will often see people driving with some kind of distraction distraction,
something which is taking their attention away from the operation of the heavy
projectile they are steering, which could easily kill them or those around
them.
Distractions like, talking on their cell phone, or even worse, looking at the
screen of their cell phone. Distractions like, allowing their 10lb dog to stand
on their lap and look out the driver-side window. Distractions like, gawking at
the pretty houses off to the left or right of the road. If the distractions
alone weren't enough, all too often I will also see people driving less than a
few seconds behind the vehicle in front of them.
I think people drive with the best-case scenario in mind: "everything is going
to work out, and I will arrive safely at my destination." Whereas I tend think
about the worst-case.
----
When learning how to ride a motorcycle the instructor told us to ride "as if we
were prey." A useful mindset to adopt: assuming that nobody out there notices
you, and if push comes to shove in an accident, you will always be on the
losing end.
My phrasing of the advice, influenced by learning to fly an airplane, where the
responsibility of "Pilot in Command" is drilled into the bright-eyed student
pilot, and by being "prey" on a motorcycle on California highways is simply:
**Nobody is looking out for your safety but you.**
----
Unfortunately on the public roads, with pedestrians, cyclists, motorcyclists,
tiny cars, big trucks, and everything in between, it's much more complex. You can
be the most prepared, well-lit, cyclist, but you're still going to lose in a
toe-to-toe with a distracted driver.
When somebody drives unsafely, and things go wrong, the *best-case*
scenario is that they only injure themselves. The worst-case, and unfortunately more
likely, scenario is that they hurt and [kill
others](https://en.wikipedia.org/wiki/List_of_motor_vehicle_deaths_in_U.S._by_year).
As a frequent walker, rider, and driver on public roads, please take your
responsibility more seriously, and drive like lives depend on it.

title: "Collecting rain, an on-going experiment"
tags:
- croyfamilyfarms
- rain
---
My neighbors must surely think that I am some kind of lunatic. Last spring I
dug up half of the dying sod in the front yard and installed three 8x4 foot
raised garden beds. Then, last fall, I started banging around with a few, bright blue,
55 gallon food-grade steel drums, in the car port, which I picked up to catch
rainfall for my [garden](https://twitter.com/croyfamilyfarms). In this post, I
will detail my initial results using a home-brew system using these metal
barrels.
While Sonoma county is not in drought, and hasn't really been off target
rainfall in recent years, the concept of catching and storing excess rainwater
is one which appeals to my "sustainable gardener" ethos. Second to that, I
strive to be **cheap.** Therefore, if I wanted to store water for use in the
garden, I needed to find a way to put together a rain collection system for not
a whole lot of money. I was able to acquire five of these blue barrels
for _zero_ dollars, quite the steal! Some researching online leads me to believe
that these barrels may only hold up for two to five years depending on how
rapidly they rust as the seasons come and go. This motivates another two
criteria for my rain-collection system: simple and easily replaceable.

</center>
### Hardware and Design
The priciest component of the setup is one which I expect to last effectively
forever, the downspout adapters. These adapters are a thick plastic which
should survive the elements, and are designed to reduce sending sediment,
leaves, and other garbage down into my rain barrels, helping keep the barrels
themselves simple. The cost of the adapters also factored into the design of
the system. Since they were the most expensive component, I aimed to use as few
downspouts as possible, and join barrels together into barrel systems which
could be fed by a single downspout.
At the top of each barrel is a large threaded hole, roughly 2" in diameter,
and a narrow 3/4" threaded hole. The 3/4" hole set the standard for sizing
piping I used to connect everything together.
Initially I looked at purchasing and fitting a hand-pump to the larger 2"
threaded hole. There are many hand-pump assemblies which can be purchased but
the cost was prohibitive, from $30-50 for lower quality plastic pumps, up to
$200 for durable metal hand-pumps.
I ended up drilling holes in the sidewall towards the bottom of each barrel
large enough to insert a 3/4" threaded bushing, which a friend welded into
place. Be careful when buying drill bits and always wear your safety glasses.
I sheared the guide bit of one of the circular drill bits when creating the
holes in the barrels and sent it flying across the workshop. The downside to
working with steel drums is, as you might expect, steel is _hard_. I drilled
the holes about 4-5" above the base of the barrel, to allow sediment to settle
to the bottom without clogging the output valve.
When my friend finished with the barrels, I set about connecting the different
barrel systems using the following hardware:
* A few 10' lengths of Sched 40 3/4" PVC pipe
* 10 3/4" threaded-to-unthreaded PVC couplers
* 5 threaded 3/4" plastic ball valves
* 5 threaded 3/4" metal nipples
* 2 unthreaded 3/4" plastic ball valves
* 4 unthreaded 3/4" PVC plugs
* 6 unthreaded 3/4" PVC T-fittings
* 2 unthreaded 3/4" PVC 90&deg; elbows
* 2 large band clamps
* PVC cement
I won't dwell too much on the actual pipe fitting, since anybody with a
measuring tape, hacksaw, and PVC pipe can measure out and connect pipes
successfully. In my installation there are two "barrel systems," connected to
two separate downspouts. Each barrel system is connected together through the
welded bushings (bottom piping, egress), and through the top 3/4" threaded
hole (top pipeline, inlet).
The top piping allows water and air to be exchanged as the barrels fill. The
bottom piping, which is itself independently valved for each barrel, allows
equal filling of the barrel system and provides the spout for pouring water
into a watering can.
The top piping is sealed with PVC cement, except for the inlet pipe which I may
wish to change the length of later. The bottom piping is also sealed with PVC
cement, except for the egress pipe which I may wish to change the length of
later as well.
The water pressure for the system depends on the "height" of the water stored,
so each barrel system is also raised on stacked cinder blocks. If you intend on
raising water barrels, use cinder blocks, or cross-braced 4x4 pieces of wood
because **water is heavy**. When considering water pressure with such a system,
it is important to consider the _top_ height of the water, not the height of
your spigot. When the barrels are full, the water height is about 5', but as
the water level lowers, the pressure will drop accordingly. Since we're only
filling watering cans, instead of attaching hoses, this isn't a concern for us.
But if we were to attach a hose, it would be important that the hose-height
during use remain below the top-height of the water in the barrels.
---
**NOTE**: My first design used brass valves, which look like a normal hose
spigot, do **not** bother with these. They restrict the water flow, only use
ball valves which, when turned, allow full use of the pipe diameter.
---
Cumulatively, once I experimented with the design, each system took no more
than 30-45 minutes to assemble, not including curing time for the PVC cement.

</center>
### Mistakes Made
Of course, I made some mistakes in this experiment, many of which can be
corrected as soon as the barrels are emptied for the season.
* The downspout near the "south crop" receives the water from almost the entire
backside of the roof and can fill in less than a couple hours during a steady
rain storm. I want to add more capacity to that side of the house, which would
likely require re-orienting the barrel system.
* The barrels shouldn't be sitting level but should slope slightly to allow air
to push up through the exposed 3/4" threaded hole in the top where water
enters. Currently, two of the barrels are leveled incorrectly and air gets
trapped as the barrels fill with water. Unfortunately this air must be manually
allowed out, by unscrewing the plug in the larger hole, in order for those
barrels to fill entirely.
* The downspout chosen for the "north crop" receives an adequate amount of output
and also rapidly fills during a steady rain. But the water requirements for the
north crop, which receives 12+ hours of sun during the summer, will far outpace
supply. Although I am experimenting with better water conservation techniques
for the north crop this summer such as: rice straw covering. oolas, and
better timing for sporadic deep waterings, I will definitely serve the north
crop the entire summer with water from the rain barrels.
* The lip of the barrels should be shielded from the rain with a roof of some
form, as water can collect in the tops of the barrels and sit stagnate for
mosquitoes or rust.
After the 2017 season has depleted the rain barrels, I expect to spent a
weekend inspecting, reconfiguring, and improving the system, but that will have
to wait until all that heavy water is gone.
### Conclusion
The most significant conclusion that I can draw from this experiment, and the
data I have collected, is that my wife is **incredibly** tolerant to my
nonsense. Bright blue 55-gallon steel drums aren't the most inconspicuous
addition to our yard, but it seems that my idiotic excitement at barrels full
of water wins her over.
A more practical conclusion is that this project has been worth it, for no other
reason than making me really consider my **water budget** for the season. I
know for a fact that I will not reach September without depleting all 275
gallons of stored water. That's okay, the water is there to be used, but I'm
considering how much water different plants, soil types, and plot locations
need.
Another conclusion to take away from the first year of this experiment is that
**cost is king.** When I first scoped out rain barrels, some vendors in the
area, including our local recycler, were charging $25-35 **just for one
barrel.** I'm not aging fine wine in these barrels, I'm storing dirty water
which rolled down off my roof. While I didn't keep detailed receipts on this
system, I estimate that I spent less than **$100** total. Considering the cost
of water, with this cheap of a system, I am still unlikely to break even unless
the system is usable for 5+ years, which I doubt will happen. In spite of any
financial incentive, the rain water is unfiltered, and also not chlorinated,
which I expect to be better for the overall plant and soil health. Only time
will tell however.
Although the system is small, it's preventing 275 gallons of drinking water
from being used for agriculture, and at the end of the day (for $100) that
makes me feel good.

title: "Starting an ambitious 2017 growing season"
tags:
- croyfamilyfarms

---
Spring has officially erupted in Sonoma county, with the immense amount of
biological activity we have come to expect from one of the more productive
regions of the country. On our meager parcel we have more plants, with more
variety, than ever before going into the ground. With two seasons under our
belts in the "south crop" and one season with the "north crop," I absolutely
couldn't wait for the cold nights to pass, and am pleased beyond belief that
Spring is finally upon us.
### Plants
There is enough variety this season that we need to break things up by plant
type, how exciting! Generally speaking, our varieties of plants break down into
fruits and fruiting vegetables, root plants, and herbs.
Another experiment I'm starting this season is planting of microgreen
rotations. Microgreens can be effectively grown in trays on a rotation, and
require a few weeks to germinate the seeds but once the greens reach 4-5" tall,
they're immediately cut with scissors for salads. I am omitting microgreens
from the rest of the post because the seeds are still in the bags and I am
still at the design stage for the trays and rotation.
Some of plants listed aren't yet directly seeded or transplanted, but will be
before the end of April, those have been marked with an asterisk.
#### Fruit/Vegetables
* Tomato: New Girl (Early Girl variety)
* Tomato: Julia Childs (A slicer variety from Harmony Farms in Sebastopol)
* Tomato: Roma (sauce)
* Tomato: Principe Borghese (sauce)
* Sugar snap peas
* Bush beans (\*)
* Leeks
* Scallions
* Corn (\*)
* Zucchini (\*)
* Blueberries
* Lemons
Tomatoes are always a big hit in the garden, as are my sugar snap peas.
Currently both are in the ground and established. As I did last year, I started
snap peas from seed but purchased tomato starts. Unlike last year however, I
have two full bed-length rows of snap peas planted (8' rows), instead of one
4' row. The tomatoes are laid out differently than last year too, with the
shorter plants (sauce tomatoes) planted in the southern end of the bed so it's
not shaded by taller plants during the morning transit of the sun.
New this year are leeks, also started from seed which, currently, look like
nothing more than little green wisps poking out of the earth. I'm still unsure
what to expect from them.
Also new this year will be bush beans. Unlike the sugar snap peas which require
something to climb up, bush beans are supposed to support themselves and grow
nice and bushy. We'll be dedicating part of one of our north crop garden beds
to the "bush beans experiment" this season.
#### Root Plants
* Potato: Yukon Gem (Yellow creamer variety)
* Potato: Desir&eacute; (Red creamer variety)
* Radishes
* Garlic
* Hops: Magnum and Sterling cultivars.
* Purple onion
* White onion
The potatoes are fun new experiment this season. In the "south crop" there are
a couple beds which receive decent sunlight but haven't performed well with
tomatoes or peppers in years past. I haven't grown potatoes before so I'm
uncertain what to expect as far as yield is concerned.
I'm also trying radishes again, which I have am planting in the "north crop" as
a bed-liner to capture some additional sun and water from otherwise unused
space. The older seeds which I used for the first two rows had a 90%+
germination rate, so I have high hopes for some small tasty salad radishes
around Memorial Day.
The onions are more out of laziness than anything else, sometimes we don't eat
onions fast enough, and they sit on the counter long enough to sprout. Whenever
something sprouts in my kitchen, I throw it into the ground. My friend, Farmer
Josh, grows a few rows of purple onions so I don't feel particularly motivated
to spent precious bed space on them, when I can trade some snap peas for fresh
onions.
The hops continue to be more fun and decorative than anything. The root systems
are now well established, and I continue to enjoy learning about the hop
growing process, but it's unlikely the hop cones at the end of the season will
find their way into any beers.
#### Herbs
* Thyme
* Genovese Basil
We do truly need more herbs but I just hate dedicating garden space to it.
Depending on how things pan out around the garden, some parsley may find its
way back into the mix.
### Soil
As I read more about organic and sustainable gardening, the more I am coming to
appreciate soil health. To think that our entire civilization depends on
something as simple as soil health and biodiversity is still something which
amazes me.
Because I'm working in enclosed and raised garden beds, I don't worry much
about soil erosion. Additionally, for better or worse, our area of Santa Rosa
is covered with absolutely awful compact clay, so under my beds there isn't
much transfer of moisture or leaching of minerals likely.
For most of the garden beds, soil preparation consisted of aerating and folding
in chicken manure. This is a fairly rudimentary preparation, once fruit
vegetables get nearer, I'm planning on doing proper soil tests for the first
time to make sure all my tomatoes turn out nice and juicy.
For the garden beds which are hosting potatoes, I employed an old gardening
technique which involves trenching the garden bed, laying down rice straw,
placing seed potatoes over it, and then covering with a few inches of loose
soil. The straw helps give the roots some loose space to grow into when the
seed potatoes are just starting out. Unlike the fruit/vegetable plants, root
vegetables need extra care taken for "hilling" during the growing period.
Meaning we'll want to build up soil around the stem of the plant as the season
progresses. For the potatoes, between the trenches I have a tall mount of dirt
which I will be using to hill as the tubers start to appear on the stems.
Unfortunately, due to soil compaction, loss of soil during harvest, and other
factors, the "soil reserve" which we had last season has been spent topping off
beds. Soon we'll need to pick up another cubic yard of garden soil to ensure we
have the necessary surplus on hand for hilling and potting plants.
### Challenges
Gardening wouldn't be much fun if it weren't challenging along the way. Thus
far the largest challenge is the same as last year: managing soil moisture
during the hot days. Our primary garden soil purposefully crusts over on the
top to preserve moisture in the soil below. The downside of this is watering
can be more challenging as a first-pass with water must first be done to soften
this "crust" and then after a few minutes a deeper watering can be achieved.
The awful, but native, clay soil is also a persistent challenge. This year we're
attempting to reclaim some parts of the yard with decorative flowers and some
basil plants. It's too early to tell how well the transplants are rooting but
I'm not very optimistic right now. The clay soil captures moisture quite well,
but once dried it's almost indistinguishable from rock. Depending on how this
smaller, almost entirely native soil, area performs this season, I may amend it
next year with some sand and compost to help loosen it up.
### The path forward
By the end of April, I am expecting to have seeds, transplants, or plants for
everything in the ground. I also expect to be planning the rest of the rotation
through the garden for late May. What I haven't successfully done in the past,
except with corn, is rotate multiple plants through the long California growing
season. Radishes for example, should be harvested in about a month, snap peas
in about two and a half months. Since we started earlier this year, this means
we should be able to get a good full second (at least!) sowing of a number of
our plants before the end of the productive season in October.
With the experience of a couple years in this location, this will be the first
year where I operate more systematically like a farm and less like an
experimental garden, so I'm looking forward to the long days of sunshine ahead!
