1. Grow the seedlings in the greenhouse - protection against birds

Sowing seedsin a primitive and simple gardening not using mulch the result will be like this: many seeds are not germinating, or they are eaten by birds [web03]. So there are measures: one can cover the planting bed with mulch and the birds will not see the seeds (see the website about mulch and mulching). When the sowing action is in a greenhouse there is much more wamth and seeds germinate much faster. They are germinating in a very reliable way with high temperatures and they are protected from birds [web03].

Greenhouse made of old windows [34] - Old Bus as a greenhouse [37] - Interior [38] - Mini greenhouse on a rear window in a car, drawing [41]
In metal vehicles, the sun is very hot, even hotter than in a greenhouse, and the plants grow very fast ...

Best greenhouses made of old cars, bus vehicles, train coaches
With old cars or old bus vehicles (without motor, no axes, no tires) or also with old railway cars one can install them in the sun so there will be excellent greenhouses with them because the body work and the windows will become really hot in the sun, partly over 50 degrees. Paint it black and it will even become hotter. When the vehicles are half in the earth, in winter the earth will give a certain heating so it's not so cold inside.

Pit greenhouses made of cars, buses, coaches
Being installed half in the earth underground this comes out as a pit greenhouse which can be used also in winter times because the earth walls are equilibrating the cold. Website about pit greenhouses "Walipini" see here - link.

But there are more tricks:

Accelerate germination with covered raised beds: To accelerate germination, you can cover bordered planting beds or raised beds with jute. This causes a higher humidity and a higher temperature. It saves at least one week during the sprouting of seeds. Concretely, e.g. carrot seeds were scattered and for germination, the beds were covered with jute bags. The seedlings do not dry out and are not eaten by birds [web03].

Seedling beds covered with jute [12]

Plexiglass hardly weathers, is UV-resistant [web13]

Plexiglas is more transparent than glass with a transparency coefficient of 0.93, is very stable, is hardly weathering, moisture does not matter and is also resistant to chemicals. Outdoor plexiglass can harden and become brittle due to temperature fluctuations. Plexiglas is easy to cut. Plexiglas needs good care. Over the years, it tends to become yellow. Plexiglas can serve as a roof for undemanding people [web14].

[Yellow is a warm color and is therefore a positive color for growing plants - see the healing forces of the colors - link].

Seedlings in several layers: seedlings can be stacked - but the seedling greenhouse must be made of fabric, glass or plexiglass and must not be a plastic foil, because plastic releases microplastics into the air and causes air poisoning.

Stack seedlings in small greenhouses - it must be cloth, plexiglass or glass
NO plastic and NO plastic air - And it should be storm proof ...

Mobile seedling greenhouse: You can set up a mobile seedling greenhouse with glass on a big cart so that the greenhouse then moves from field to field to transplant the adult seedlings into the flowerbeds [web03].

Mobile mini greenhouse for seedlings 01 [36] - Mobile mini greenhouse for seedlings 02 [42]

The mini-greenhouses may be made of fabric, glass or plexiglass, NOT of plastic foil / film, because there is constantly microplastic in the air.


2. Tricks with seedlings

For seedlings there is no need to use plastic holders, but instead

-- seedlings germinate in toilet rolls [web05]
 


      WC-Rollen unten
                          zuammenfalten und in Eierkartons stecken
Fold toilet rolls and put them in egg cartons [10]



-- seedlings also germinate in egg cartons [web06] or in egg shells [web10]

Keimlinge wachsen in Eierkartons   Keimlinge wachsen in Eierschalen: 
Seedlings grow in egg cartons [3] - seedlings grow in eggshells [4]

3. Cover seedling beds: Cover the seedbed - cover the seedlings

In order to protect the seedlings from birds and at the same time to create higher temperatures for rapid germination, the seedling beds can be covered with transparent cloth - but better is of course glass, plexiglass or cloth or jute:

Aufklappbares Keimlingsbeet muss aus
                  weissem Stoff sein  
Aufklappbares Keimlingsbeet muss aus weissem Stoff sein [14]

because plastic (PVC) release microplastic into the air and poison the air.


Cover seedlings individually with glasses etc.

Or you can also individually cover the seedlings with glasses:

         Anzuchtglocke
                  viktorianisch
Cultivation bell in a Victorian style [16]

Using sawn, half PET bottles for seedlings provokes microplastics polluting the air.

Regrow vegetables and herbs in a glass of water

Lettuce: let stand 5cm and let the root regrow in a glass of water goes with lettuce (after 5-7 days plant it in the raised bed) (10 '')

MINT: use up the side leaves, let intact the leaves at the top, in the glass of water the roots grow back again (17 '')

LEEK: leave 3cm from the root, in a glass of water the roots grow back, transplant after 5-7 days (28 '')

CELERY: Leave 5cm from root, roots grow back in water glass, plant after 5-7 days (37 '')

BASIL: use up the side leaves, let intact the leaves at the top, roots grow back in a water glass, replant it when the roots are 5cm long (46 '')

ONION: Cut around the root and leave about 3cm, put this in the soil and so new onion is growing again (56 '')

GARLIC: Lay a garlic clove in a horizontal way flat in the soil and cover with approx. 2cm soil (1'2 '').

[These experiments are not confirmed yet. Try it out yourself if it works good or not].


4. Automatic watering with water kettle and shoelace irrigation


Automatische Bewässerung mit Wasserkessel und
                    abgeschnittenen Schnürsenkeln
Automatic irrigation with kettle and cut shoelaces [59]

Shoelaces and water kettle: Buy some shoelaces and cut off the ends. One end is installed deep in the root area of the plant and the other end is connected to a water-filled kettle. The plants suck the water coming from the shoelaces.

Different shoelaces: The cut shoelaces let pass the water differently. Round laces let pass the water more easily than flat shoelaces. Accordingly, the positions of the plants must be differently according to the cind of shoelices being applied. In summer always round shoelaces for much water transport.

It was surprising to observe that the plants suck their water above all during the night, and are also growing above all during the night.

Shoelace irrigation: plants absorb more water during the night than during the day - plants grow more at night than during the day (!) - in summer, the water pot must be higher

Surprisingly, the following could be observed:
-- that the plants suck water above all during the night, and are growing above all during the night
-- that in summertime in glaring sunshine this shoelace method DOES NOT WORK because the sun dries out the laces, in half shadow or in the shadow it's working, respectively
-- in summer with bright sunshine and water pot must be above the plants, in spring and autumn with less sunshine, the water pot must be lower, so that the plants are not "overwatered"
-- very good is also forming a net of connections between the plants with shoelaces so the plants can exchange signals and minerals.


5. Build small greenhouses - the mini-greenhouse for the garden

A greenhouse is warming by transparent areas in sunlight:

-- with old windows

                  Fenstern   Keimlingsbeete aus alten Fenstern, die
                  geneigt sind 
Folding mini greenhouses made of old windows [9] - Seedling beds made of old windows that are inclined [13]

Plastic films are to be rejected because they release microplastics into the air and poison everything.

With enough space, you can also use straw bales to build small greenhouses, and eventually one can install a "hot" permaculture soil with a compost layer in the soil. Not use plastic film, otherwise the air is poisoned with microplasitk - it must be glass or plexiglass or fabric.

[The color of the fabric has to be tried out what is best, red perhaps, the hottest color? Yellow, orange and red are hot colors, green half cold, blue cold, brown is warm again - see Healing forces of colors].

Strohballen sind ein guter Isolator
                              (ein R-Wert von 1,5 bis 3 pro Zoll).

                              Erdboden zusätzlich
This small hothouse consists of straw bales and old windows. Compost and natural fertilizer in the soil additionally heat the soil [57]


6. Warm raised bed + greenhouse attachment = super-raised bed greenhouse

You can build a warm permaculture raised bed (with wood, compost, manure and leaves as layering) as a greenhouse - with glass, plexiglas or fabric. So you can reach very high temperatures and the plants germinate and grow in no time:

7. "Walipini" - the lowered greenhouse (pit greenhouse) for ALL SEASONS

With a Walipini EVERYONE and EVERY LAND can run their own agriculture all year long.

                  hohen Anden in Bolivien mit schädlicher Plastikplane

Half underground greenhouse in the high Andes in Bolivia, Mother Earth always gives off heat (unfortunately this pit greenhouse is with plastic foil tarpaulin as a roof) [43] - Half underground pit greenhouse in Spetchley Gardens, UK. Stairs go down to the entrance on the right. [44] - There is missing a hail protection with chicken wire over the roof.

The only big investment for a pit greenhouse is to build a pit. Then almost everything goes by itself with Mother Earth:

1. The microclimate in pits is stable because the soil layer is reacting slowly to climate change: Due to the thermal inertia, the deep soil is always moderately warm in winter and moderately cool in summer, because the soil layer takes several months to adapt to the outside temperature.
2. 1.2m: The minimum depth of a pit greenhouse is 1.2m.
3. Wall materials: Wall material may be: earth, earth bricks, natural stones, earth bags, water barrels.
4. The walls become a heating battery: the walls store the heat and radiate the heat during the night, therefore it's never too cold during the night, in other words: the earth walls work like a battery and give off the warmth during the night.
5. Heating from 5 sides: there are 4 heated walls and the heated floor during the night: The heating during the night comes from 5 warm sides: 4 warm walls and the warm floor - in a normal greenhouse there is only 1 warm side: the floor.
6. Heating with water barrels at the back side: This is the best heating method in a Walipini greenhouse because water stores warmth the longest and radiates it the longest during the night, but the water barrels need more space.
7. Watering with rainwater in water barrels: rainwater can be collected in the water barrels.
8. Watering of plants with rainwater: When the water barrels are full one can install an additional water tank for watering the plants with living water.
9. Build 1m above the groundwater level: Pit greenhouses must be built at least 1 m above the groundwater level, otherwise a major water damage is possible.
10. Window front greenhouse: window front towards the sun: The window front of a window front greenhouse must always be directed to the sunny side: In the northern hemisphere, the window front is facing south, and the back wall (north wall) takes most of the heat. In the southern hemisphere, the windows face north and the back wall (south wall) stores most of the heat.
11. Window front angle: The angle of the main window side is optimal with a 90 degree angle to the sun during the winter solstice - or the window side is shaped in the shape of a half U, which corresponds to every possible sun angle.
12. Small windows for ventilation: The window front has small windows for ventilation possibilities during summer times.
13. Window materials / transparent roofing materials: Windows are made of glass or plexiglass (four-layered polycarbonate sheets) with a thickness of 7/8". The plexiglass is then bendable to form half a U.
14. The tube pit house: The longer a pit greenhouse is (a tube pit greenhouse), the warmer it will be and the more stable the temperature is at night. At the same time, a pit greenhouse must have no holes at night to keep the cold air out.
15a. Roofs (transparent): may be in the form of a V (glass, plexiglass) or in the form of a U (plexiglass). Plastic wrap is TOXIC, releases microplastic through weathering and is poisoning the air and everything.
15b. Roofs (solid) can be a normal roof combined with a window front to the sunny side, or the roof can be on a mountainside the mountain itself combined with a window front to the sunny side.
16. Plastic film / foil / wrap is poisonous because the weathering causes microplastics to be released into the air and the air and everything is poisoned.
17. Water circle, drainage, ventilation: Everything must be watertight, there must be no holes in the structure, there must be drainage, and for summer there must be ventilation or windows to open.
18. Avoid hail damage with chicken wire: Glass roofs can be protected with chicken wire. When the roof is solid in combination with a windows front one can attach a small "canopy" with chicken wire so there will never be any hail damage.

Do not use plastic sheeting: do not use plastic foil / film / wrap because weathering causes the sheeting to constantly release microplastics into the air and the air and all is poisoned. A plastic sheet is weathering within in 3 to 4 years.

                            Schema The pit greenhouse / hothouse "Walipini", scheme (pit greenhouse) [45]

The plants are protected and electricity is saved. A A pit is installed (at least 1.2m), the inner walls are covered with stone, clay bricks or other natural material - dense material that absorb heat and hold heat back.

The depth is between 1.2m (4ft) and 1.8m (6ft) [depends on the height of the plants].

Water barrels filled with water can absorb even more heat.

In case of instability, the wall can be stabilized with pressed earth bricks.

The sun heats up the greenhouse through the transparent roof. [Web12]


The best semi-submerged pit greenhouses are those
1) with a fixed roof,
2) with a window front on the sunny side and
3) with a solid wall on the shade side, where heat is stored.

This avoids any hail damage. In addition, it is easy to create permaculture raised beds and corridors. The cold air is concentrated in the corridors at night and you no longer have to bend down to the ground.

You can also create the pit deeper, so that only one roof looks out:

                        - Querschnitt
Pit greenhouse "Walipini", here a completely submerged greenhouse from Bolivia with sun roof - cross section [58]

Such a sun roof must be made of fabric, glass or plexiglass and needs hail protection with chicken wire. Plastic foil releases microplastic into the air.

At the pit greenhouse on the next photo there were raised beds installed with a corridor in the center (working as a cold air sink) where the colder air will be during the night not harming the plants in the raised beds and plants go on growing during the night.

The slope pit greenhouse / Slope greenhouse

A small slope pit greenhouse: Walipini, sunken greenhouse on the mountainside with window front to the sunny side [51]

On the mountain slope with an earth layer it's easy to install warmth-storing earth walls, with raised beds and with corridors as cold air sinks - and this will be a tropical place.

Here is a scheme, the slope pit greenhouse by Mr. Mike Oehler:

Book by Mike Oehler: The Earth Sheltered Solar Greenhouse Book

With a permaculture layering in the raised bed with wood, manure, foliage and compost, the raised planting bed becomes warm and moist. Watering is not necessary and the plants are growing even faster.

Here is such a slope pit greenhouse (slope greenhouse) on the hillside under construction:

Greenhouse section in an earthship
The next pit greenhouse has a sun-window front and a fixed roof. The roof is covered with black foil to keep it as warm as possible. The film is problematic because it releases microplastic into the air. Better is a solid roof painted black. Metal roofs are also very hot. This house on this photo here is the model of an earthship with 1m thick earth walls made of old tires filled with earth storing the heat combined with a greenouse section on the window front.

Grubengewächshaus
                  mit Fensterwand zur Sonnenseite und Abflusskanal
Pit greenhouse with window wall to the sunny side and spillway [48]

Small windows within the row of windows are open for ventilation above all during summer times. As hail protection, one can attach a protective grid with chicken wire as a canopy.

Apparently, old tires were used here for the base of the window wall where the planting beds of the greenhouse part are. This is arquitecture by architect Michael Reynolds - link.

Principally one can sink old railroad cars half in the ground and then use them as greenhouses with a window front to the sunny side and the other window front is closed with an earth wall from outside.

The hail protection is also missing at the next pit greenhouse:

Interior of the tube pit greenhouse of Roald Gundersen in Wisconsin ("USA") [50]

This greenhouse is 2800 square feet (s.f.) - and is insulated with straw bales. The support structure is made of Robinia wood, grows fast, is robust, rot-proof and is abundant in Wisconsin [web12].

The larger a pit greenhouse, the more efficient it is because the temperatures in a small greenhouse change faster [web12].


Added pit greenhouses attached to the residential home

The adding of a pit greenhouse is also efficient because the residential home is like an insulated body without extreme cold nor extreme heat. One can increase the heat painting the wall and the structures in a dark color or even in black because with black color the walls and structures are warming most. Combined with a permaculture raised bed there can grow also tropical plants here.

The slope pit greenhouse with plexiglass roof and water barrel heating on the shady back wall

The pit greenhouse in Bozeman (Montana) is built of wood with a roof of plexiglass. It has a cold trench and a water barrel heater on the back wall. Peppers, small radishes, chard, coriander, basil and zucchini also grow here in winter. Even at below 0ºC during the day (for example, at 28º Fahrenheit, -2ºC), the temperature in the greenhouse can rise to 47ºC (117ºF) if you forget to open the doors (!). Water barrels on the back wall keep the heat of the day and radiate the heat during the night. The rainwater can be collected and used for watering, if you want to pour. In permaculture raised beds with wood down in there you do not have to water the plants more ...

8. Greenhouses made of plastic film / sheet / wrap or PET plastic bottles release microplastic into the air - very toxic - must be forbidden!

A plastic sheet will be destroyed by weathering in about 4 years, and a PET bottle will be destroyed by weathering in 10 to 20 years. This is why it is not a good idea to use plastic films or PET bottles for building houses, because the weathering caused by the temperature differences of day and night destroys the plastic films and PET bottles and thus releases microplastics into the air. This air is absorbed by the plants, so that the microplastic also gets into the plants. Greenhouses must therefore be made of glass, plexiglass or fabrics.

Plastic greenhouses (plastic film / sheet / wrap or PET bottles, etc.) contaminate the air with microplastic - must be forbidden!
