There are some inclusions here with which other data I have does not agree. Broccoli, Brussels sprouts, Cabbage and Kale are commonly held to require more sun to produce larger yields. Probably the difference between what you can get away with to produce a result versus what is optimal.
Greenhouse Chicken Coop
When a coop shares a wall with a greenhouse, four exchanges happen without any equipment. The chickens exhale CO2 that the plants use for photosynthesis. The plants release oxygen that circulates back to the coop. The chickens radiate enough body heat to smooth temperature swings on cold nights. And the manure composts into the fertilizer the greenhouse beds need.
No electricity. No pumps. Just a shared wall with adjustable vents.
The heat contribution is modest — it won’t replace insulation in a harsh winter, but it smooths the overnight temperature swing that kills tender seedlings. The CO2 is modest too — not commercial greenhouse levels, but enough to replenish what the plants consume in a sealed winter greenhouse.
What makes it work:
– Adjustable vents in the shared wall — open during the day for gas exchange, closed at night to trap warmth
– Wire mesh barriers so chickens can’t access growing beds. They’ll scratch up seedlings and dust-bathe in your soil if given the chance
– Deep litter on the coop floor — eight to twelve inches of straw or wood shavings that absorbs moisture, reduces ammonia, and composts in place
– Enough ventilation to prevent ammonia buildup. Chicken manure in an enclosed space harms both plants and birds without airflow
Four exchanges running continuously. The animals feed the plants. The plants clean the air for the animals.
The smartest design is letting biology work together
Growing Containers
The same tomato plant in four different containers produces completely different yields. The container is not a secondary detail.
The fabric grow bag performs best for a specific reason: when roots reach the permeable wall, the air at the surface desiccates the root tip and the plant responds by producing dense lateral branching further back — a process called air pruning. In a solid plastic pot the root circles continuously until it becomes pot-bound, compressing its own vascular system. In a fabric bag the root system fans outward in branched layers, maximising the volume of compost it can access.
Fabric bags also run significantly cooler than dark plastic containers. A black plastic pot in full summer sun can reach soil temperatures that slow root activity and reduce fruit set. A fabric bag in the same position will typically stay 6 to 10°C cooler.
What happens in each container:
Dark plastic pot — traps heat. Root temperatures above 28°C in summer conditions are possible. Roots circle and become constrained. Inexpensive to buy, costly in yield.
Fabric grow bag — roots branch rather than circle. Better oxygen at the root zone, better water distribution, better production. The best choice for tomatoes on a balcony or terrace.
Terracotta pot — transpires moisture through the walls, which cools the root zone naturally and prevents waterlogging. Excellent for herbs and drought-tolerant crops. For tomatoes it increases watering frequency, and in hot dry summers it can stress the plant. Works well with consistent attention.
20-litre bucket — conducts temperature change rapidly. Roots experience cold nights and warm days as sharp fluctuations rather than buffered changes. Works for tomatoes if the bucket is partially buried or insulated.
Soil Temperature Peas vs Tomatoes
Your peas are climbing two feet in a week. Your tomato transplant hasn’t moved since you planted it ten days ago. Same bed. Same soil. Same water.
The tomato isn’t sick. It’s cold.
Push a soil thermometer four inches deep. If it reads below sixty degrees, that number explains everything.
Pea roots activate in the low forties. At fifty-two degrees they’re running at full capacity — which is why the pea is sprinting while the tomato sits still. Tomato roots don’t come online until the soil hits sixty. Below that, they’re alive but functionally parked. Root tips aren’t extending. Nutrients aren’t moving. The plant can’t take up phosphorus or transport calcium properly in cold soil.
That purple tint on early-season tomato leaves isn’t a deficiency you need to fix with fertilizer. It’s cold soil locking phosphorus into forms the roots can’t absorb yet. The fix is warmth, not a bag.
The practical version:
– If soil is below sixty — leave tomatoes, peppers, and eggplant in their pots on the porch. They’re not gaining anything in cold ground
– A tomato planted two weeks later into sixty-degree soil will match and overtake one planted into fifty-two-degree soil within days
– The early plant doesn’t get a head start. It gets a cold start
– The peas, lettuce, spinach, and radish are fine right now — their roots were built for this temperature
The thermometer tells you what the plant already knows.
Peat Moss or Coco Coir? Which is better for your needs?
The key advantage (this is where coco coir shines)
Coco coir has a unique fibre structure that:
Holds moisture evenly
Maintains airflow at the same time
Prevents compaction over time
That means:
No waterlogging
No dry patches
Stronger root systems
Peat moss is harvested from decomposed plant material in peat bogs. It’s been widely used because it:
Retains moisture well
Is lightweight
Has a slightly acidic pH
But there’s a catch…
Coco Coir Vs Peat Moss (Side-By-Side)
Feature Coco Coir Peat Moss
Water retention Excellent High
(balanced) (can become waterlogged)
Aeration High Low over time
Sustainability Renewable Non-renewable
pH level Neutral Acidic
Reusability Reusable Breaks down quickly
Aussie climate
suitability Excellent Less ideal
Water Retention: Why Coco Coir Performs Better
Here’s where most gardeners go wrong.
They think, “More water retention is better.”
But that’s not true. The real goal is balance.
Peat moss:
Holds water tightly
Can suffocate roots if overwatered
Coco coir:
Holds water and air at the same time
Releases moisture evenly
This is why plants grown in coco coir are:
Less prone to root rot
More resilient in heat
Easier to manage
Sustainability: The Big Difference
This is one area where peat moss struggles.
Peat bogs take thousands of years to form.
Once harvested, they don’t recover quickly.
Coco coir, on the other hand:
Is a renewable byproduct
Uses waste material from coconuts
Supports sustainable gardening practices
If you care about growing responsibly, the choice becomes pretty clear.
Why Coco Coir Is Better For Australian Gardens
Australian conditions are tough:
Hot summers
Dry soil
Water restrictions
This is exactly where coco coir shines.
It helps you:
Retain moisture longer (less watering)
Prevent soil drying out
Improve poor or sandy soils
Peat moss simply wasn’t designed for these conditions.
Use Coco Coir If You Want:
Better water control
Healthier root systems
A sustainable option
A medium that works in Aussie climates
Use Peat Moss If:
You specifically need acidic soil
You’re working with certain specialty plants
For most home gardeners, coco coir is the smarter choice.
As with diets, there is no ‘One size fits all’ in gardening.
Just added something to my gardening encyclopedia I thought you might be able to apply:
Key Principle: As with diets, there is no ‘One size fits all’ in gardening.
That is why for a given approach, like watering or fertilising your soil, there are often many alternatives offered in this book. Pick the one that best suits you, your circumstances, budget and environment.
In any scenario, the worst workable technique, carefully applied is better than any better technique not applied at all.

Pick These Veggies Daily
That monster zucchini isn’t a prize. It’s the reason your plant stopped producing.
When a vegetable matures its seeds, the plant gets the signal: mission accomplished, stop flowering. Every day you delay picking, you’re telling the plant to shut down. Pick daily and the plant keeps flowering, fruiting, and producing all season.
The ones that respond most:
– Zucchini — pick at six inches. The baseball bat on the vine is why you haven’t gotten a new one in ten days
– Green beans — snap them off at pencil thickness. Once the seeds harden inside the pod, the plant stops flowering
– Cucumber — check daily. They go from perfect to oversized in forty-eight hours in warm weather. A yellow swollen cucumber is a seed factory and the vine’s signal to quit
– Okra — the tightest window. Three inches is tender. Five inches is woody. Check every day once pods start forming
– Cherry tomato — every ripe one you pick sends a signal through the vine to open new flowers. A cluster of overripe splitting fruit signals the opposite
– Basil — every pinch above a leaf pair turns one stem into two. By midsummer a regularly pinched plant has dozens of stems. An unpinched plant is one tall stalk that flowers and dies
Pick daily. The picking is the trigger
