How do you determine the slope for glazing of the roof?

@@hamadilawson4396 degree of latitude plus a constant. I dont recall anymore. It may be 31.

What made up the $18 operating costs?

I have a question if you dont mind. What is the cover crop that you plant in your beds for fixing the soil? When do you sow these and when do you cut them down. I would love to do the same this year to improve my soil. Thank you for your time. Please keep making videos, id love to see how you sow / plan your seeds for successional harvests etc. Your videos are excellent! ​@@manuelangerer-permaculture

@@Joe-yo1tmHey there and thank you very much! I use alfalfa, lupine, buckweed, vetch, beans, grains and clover. I sow these whenever I have no use for some of the space in the vegetable beds, but most of the cover cropping I`m doing happens in Autumn. But I`ve also sown some in the beginning of February when I noticed that the soil on two of my beds needs some decompaction and fertility.

Thanks!

Thanks a lot! :)

Thanks! Yes you are right, this building is not built for high productivity in terms of food production. Due to the limited light inside a passive solar greenhouse (which results from the need of good insulation) I do not think that there is a passive solar greenhouse that can put out the production of a normal polytunnel. But it enables you to grow plants that would not grow in a specific season or climate otherwise!

Yes that is a cool thing to do!

Thanks!

Thanks a lot!

Love this kind of stuff😊

Thanks!

Vielen Dank! Liebe Grüße aus Oberösterreich!

Hehe thanks a lot for your comment! More videos are coming, but first spring needs to arrive so that I can film the things I want :)

Thanks a lot!

Vielen lieben Dank :)

Thanks!

In our case, if I were to build the greenhouse again, I would even increase the glazing a bit to have a little more light for the plants. The building is far from overheating in summer. The huge amount of clay in the walls and the good orientation of the building keep it cool in the summer. The hottest temperature recorded inside in the summer was 34 degrees Celsius when it was 39 degrees outside.

Thanks a lot! This hand pump is from the manufacturer "agt".

@@manuelangerer-permaculture thank you!

Yes, that is often the case. A passive solar greenhouse is not the place of highest productivity. It is a place of multifunctionality or it enables you to grow stuff that wouldn`t grow in your climate without it. If you want high productivity then build a polytunnel. In a passive solar greenhouse there is less light and you also can get problems with aphids and other insects fast. But it is warmer in winter and cooler in summer than a normal greenhouse and that`s where the advantages are. It`s a passivly heated, multifunctional room which is perfect for starting seedlings, tropical plants and much more. It needs to fit the context, otherwise it is not worth the effort building one.

@@manuelangerer-permaculture thanks for the repy

Wir haben keine extra Beleuchtung, für unsere Zwecke brauchen wir das nicht - Mit Solarpanel und Akku wäre das natürlich eine Option. Unser Strom kommt aber bereits von einer Photovoltaikanlage auf einem Gebäude nebenan, deshalb ist hier bei uns kein Bedarf am Gewächshausdach! Viel Erfolg beim Bau, melde dich gerne, falls Fragen auftauchen!

Danke! Im Gewächshaus ist es im Winter im Schnitt etwa 5 - 10 Grad wärmer als draußen. Wenn starker Frost kommt, ist diese Spanne noch größer - Letzte Woche hatten wir in der Nacht -17 Grad, im Gewächshaus hatte es noch immer etwa ein Grad. Das gute ist ja immer, dass wenn es richtig kalt wird auch die Sonne scheint - weshalb das Gewächshaus auch gleich wieder gewärmt wird.

Danke für dein Kommentar! Ich habe das auch gemacht, habe die Rohre und den Ventilator mittlerweile abgebaut und zugeschüttet. Das System ist meiner Meinung nach enorm überbewertet und bedeutet einen großen baulichen Mehraufwand, der es nicht wert ist. Außerdem vergräbt man wieder eine Menge Kunststoff im Boden. Unser Gewächshaus ist das ganze Jahr über frostfrei und überhitzt im Sommer nicht, weil die Bauweise und Ausrichtung gut gewählt ist. Eine Erdbatterie braucht man nicht, wenn man gut baut! Liebe Grüße aus Oberösterreich!

@@manuelangerer-permaculture vielen lieben Dank für die aufschlussreiche Antwort :) so ein frostfreies Gewächshaus ist schon etwas mega tolles und eröffnet einem jede Menge Möglichkeiten und wenn das aif unserem Breitengrad sogar ohne den ganzen Plastik im Boden geht, ist es umso toller.

@@Dutlerveili Ja voll :)

Hi there! I do not have a good plan to share. But you can write me an e-mail with your questions and I will answer them the best I can! You can find my e-mail adress on my website.

google university of missouri, has plans online for a passive greenhouse@@manuelangerer-permaculture

On average about 5-8 degrees Celsius if there is no sunshine for weeks. Lowest temperature inside was 0.5 degrees when it was -20 outside.

Inside a greenhouse or outside?

Dirt and concrete tiles!

It averages on about 5°C in winter and 25°C in summer.

Yes we have some spider-mites inside the greenhouse, especially in winter! In summer I often water the plants from above, so that the leaves get washed regularly and in this way the mites dissapear during summer. In winter I don`t want to do this because the leaves would dry very slowly so the mites can spread a bit. But no problems for the plants until now. You just have to clean the fruits a bit before you eat them ;-)

@@manuelangerer-permaculture if you can add 1-2 ventilators to blow over the top of leaves, they don't like that ;)

@@DeezChords Ah thanks for the tip, I´ll try that!

The walls of the building are made from clay and wood, no vapor barrier is installed. So excess moisture gets transported out of the building through the walls. How is your greenhouse built? What materials have been used?

I´m sorry to say that I do not know any good reference books for passive solar greenhouses.

@@manuelangerer-permaculture where did you learn?

university of misouri extension has plans for such a greenhouse@@MemoryPallace

Thanks :)

also östereich wie ich , darf ich fragen von welchem bundesland?:)

Ah schön! In Kirchdorf an det Krems im südlichen Oberösterreich sind wir zu Hause :) Du?
