7 new guides, and the arithmetic most of them turn on
Logan Pierce
August 20, 2026
Good morning.
7 new guides went live since Monday, and the thread running through most of them is arithmetic nobody thinks to do. How many watt-hours. How many degrees, for how many days. How many hours before it has to be in the ground.
None of it is complicated. It is just the part that usually gets skipped, and it is usually the part the whole thing turns on.
3 quick things this week
The big number on the front of the box is the wrong number. Watts tells you what a power station can run. Watt-hours tells you how long. Shop the first and you can buy a unit that starts your fridge and then dies before lunch.
Letting manure age does not work. The outer 6 inches of a pile stay cool no matter how many months you give it. The federal standard asks for 131 to 170 degrees F, held 3 days static or 15 days in a windrow with at least 5 turnings.
After a disaster, the calendar does more for a child than the conversation. CDC puts a return to ordinary schedules, meals and school and bedtime, ahead of talking it through.
This week
Late August is the last comfortable window to start a manure or bedding pile and still get a real hot phase out of it before the nights turn. If you keep animals, this is the weekend for it.
Worth doing the calendar math backwards too. The federal waiting periods are 120 days before harvest if the edible part touches the soil and 90 days if it does not, so anything you spread raw now is aimed at next season, not this one. Two habits cover most of it: put a thermometer in the pile, and write the start date on the bin.
Portable Power Stations for Emergencies
The number printed largest on the box is usually watts, and watts is the wrong number to shop by.
Watts is a rate. Watt-hours is an amount. Watts is how fast the car is going, watt-hours is how much fuel is in the tank. Buy on the first number and you can end up with a unit that starts your refrigerator without complaint and then empties before lunch on day one.
There is also a trick with the refrigerator that almost nobody uses, and it can cut the size of the unit you think you need by roughly two thirds. The number you need is already printed on a label stuck to the appliance.
Inside: the 4-step sizing method, the 15 percent that never reaches your devices, what surge watts do to a plan that looked fine on paper, why one solar panel refills about a quarter of what you spend in a day, and the short list of things a power station will never run no matter what you buy.
Helping Children After a Disaster
The instinct is to sit them down and talk it through. That is a reasonable instinct with an adult friend. With a child it is mostly not where the work happens.
CDC guidance puts something far less dramatic first: getting back to the ordinary schedule. Meals at the usual time, school attendance, bedtime in the usual order. You cannot argue with 14 straight normal breakfasts.
The other thing worth knowing before the next storm is what a 4 year old sees when the same clip of a collapsing building replays on a phone. It may not read as one event shown 12 times. It may read as 12 separate disasters.
Inside: the age-by-age map from under 2 through 18, the 3 routines to lock down first, why the reassurance that settles a preschooler makes a 14 year old shut down, the conversation format teenagers will actually use (it is not face to face), and the CDC threshold for when to stop waiting and get help.
Fermented Foods for Preservation
A crock of sauerkraut gets sold two ways, as kitchen magic or as a science experiment that will poison you. It is neither. It runs on salt and time, and you can check the result with a $15 pack of pH strips.
The number that decides everything is 4.6. Below that pH, the organism everyone worries about cannot make toxin. Which means the salt is not the preservative and the bacteria are not the preservative either. They are just the machine that makes the thing that is. Once that lands, every rule in fermenting stops being folklore and starts being a lever you can pull.
And here is the line most guides leave out entirely. A finished ferment is not shelf stable. Not on a pantry shelf, not in a cellar, not with the lid screwed down tight.
Inside: the salt ratio by weight and why scooping instead of weighing wrecks a batch, the temperature-to-time table, the quick test that separates harmless kahm yeast from the mold that ends a batch, the 3 real options once fermentation stops, and the honest answer about where fermenting belongs in a prepper pantry.
Greywater Systems at Home
A household of 4 sends roughly 1,000 gallons a week down the drain that could be watering the yard instead. That figure comes from University of Arizona Cooperative Extension, and it is the easy part of this.
The hard part is that the rule that matters most has nothing to do with filters or tanks. It is a clock. Untreated greywater has to be in the ground within 24 hours, which rules out the very first thing most people reach for, which is a barrel. It arrives warm and carrying exactly what bacteria want, so a barrel is not storage. It is an incubator.
There is a category surprise here too. Kitchen sink water is not greywater, and the reason has nothing to do with grease.
Inside: the laundry to landscape build spec down to tubing size and outlet counts, why the three-way valve is a safety device rather than a convenience, the detergent ingredient that quietly damages soil (biodegradable on the label tells you nothing about it), the crops this must never touch, and how state permit rules manage to contradict each other.
Composting Manure Safely
Letting it age does not work. That is the sentence that reorganized how I think about the pile behind the barn.
Time turns out to be a weaker tool than heat, because the outer 6 inches of any pile stay cool no matter how many months you give it. The federal standard is specific about the alternative: 131 to 170 degrees F, held 3 days in a static pile, or 15 days in a windrow with at least 5 turnings. That is a thermometer job, not a patience job.
There is also a way for perfectly good compost to work against you in its first season. Get the carbon to nitrogen ratio wrong on the high side and the fertilizer you just spread becomes, for a while, a fertilizer thief.
Inside: the carbon to nitrogen math with real bedding numbers, the 90 and 120 day waiting periods and which crops fall on which side of them, the 4 tests that tell you a pile is actually finished, application rates by animal, and the 4 manures that never belong in a garden pile at all.
Preparing Wild Edible Plants
Almost everyone's instinct with a questionable wild plant is a hard, fast boil. For at least one family of plants, that instinct locks the problem in rather than washing it out.
The UN FAO's work on cassava is the clearest illustration I found. The enzyme that breaks the dangerous compounds down is itself destroyed by heat at about 72 degrees C, which means slow and patient beats hot and fast, and the water you pour away is doing more of the work than the fire is.
This piece is also honest about its own limits in a way worth flagging up front. Preparation is step two. There is no preparation method, none, that makes an unidentified plant safe, and there are plants for which nothing you do in a kitchen matters at all.
Inside: cold versus hot leaching for acorns and why one of them quietly destroys your flour, the 3-change boiling method and the 3 rules that make it work, the 4 reasons the old universal edibility test fails, and the one common wild plant we deliberately refuse to publish a procedure for.
Family Health History
Two documents, not one. That is the whole argument here, and it took me a minute to see why it matters as much as it does.
A paramedic standing in your kitchen has about 30 seconds to work out who you are and what will hurt you. Nobody in that situation reads a 3-generation family tree. They read a medication list and an allergy list. Your doctor, in a quiet room a month later, wants close to the opposite document, and wants the one field almost everybody leaves blank.
There is also a place where a detailed family history can genuinely cost you, and it is not where most people assume. The federal law that protects it has two specific holes in it, and both of them are worth knowing before you fill anything in.
Inside: the 7 fields to record per relative, the 8 line emergency sheet a stranger can read at a glance, the 4 places to keep a copy, the free federal tool that keeps your data in your own browser (and the reason to export it the same day you use it), and the family patterns that are worth asking for a referral over.
One picture, one gap
That is one full day for a 2 person household, written out the way you would actually write it on the back of an envelope. It takes about 20 minutes with a pencil, and it is the difference between buying the right box once and the wrong box twice.
The gap the card leaves open is the fridge line. 1,100 watt-hours looks low next to a compressor that draws 150 watts, until you remember the compressor does not run all day. Multiply the running watts by 24 and you will talk yourself into a unit three times bigger and three times dearer than you need. The yearly figure on the energy label already has the cycling built in. Use that.
Worth a watch
This one pairs with the manure composting guide. Our article can hand you the numbers, 131 to 170 degrees F, 3 days or 15 days, roughly 3 parts brown to 1 part green. What writing cannot do is show you the pile: how coarse the bedding looks going in, how much bulk you actually need before anything heats up, and what turning it looks like when somebody who does it routinely does it.
The University of Kentucky's Martin-Gatton College of Agriculture, Food and Environment has a segment called Composting Chicken Manure on its UKAgriculture channel that walks through exactly that. It is an older clip and I am linking it anyway, because the underlying standard has not moved and extension is where this knowledge actually lives. Worth watching before you start a pile this fall, especially if you keep birds or you are about to inherit a neighbor's coop bedding.
Before you go
That is the week. 7 guides, one from each of the areas we cover, so there should be something useful wherever you happen to be in this.
If somebody forwarded this to you and you would like it landing in your own inbox twice a week, subscribe here. It is free, and it stays practical.
And if you are already on the list, pick one thing off the 3 quick things and go handle it today. 20 minutes with the energy label on your fridge will tell you more than an afternoon of reading reviews.
You never know, but you can always be ready.
