Making compost: simple tricks and techniques... https://youtube.com/shorts/1S8DrHPdGHE?si=ST1VNh5RoJy-KPZs I'd punch a few holes in the bottom of the melon for drainage...otherwise, a nice idea.
Used to do a lot of compost, but learned with my greenhouse that it is best to be careful. Late blights etc from my plants, and unknowns with world wide sourcing of food in stores. I have begin to use either new bedding material, or sterilize anything before I use it in my greenhouse. While composting is good and saves money, losing the whole crop and having to throw out the growing media and sterilize the greenhouse structure and beds etc, is really a pain. In a survival situation, it could kill you. Only happened to me once, as near as I could figure out, was composting some Mexican tomatoes that were the source of a nasty blight. Here in New Hampshire, it is difficult in my area to raise tomatoes or potatoes in a garden due to diseases. Works much better in greenhouse and with sterile soil or grow media. Never under estimate the lowly "high tunnel" as I think in a real world survival situation, it could well be a game changer. It helps control climate, water, fertilization, two and four legged pests, and disease. At the same time its intensive nature gives a lot of product for a small area and over a longer time and with a relatively low initial cost and low operating costs. With high tunnels you can split your risks, several for the price of one 4 season greenhouse, and try compost in one and not lose everything. As with everything in survival, try it ahead of time when failure may hurt your ego, but not decrease your chances of survival.
I was unfamiliar with the term 'High Tunnel'.....the following refers.... High Tunnels - Oklahoma State University Your point about compost being a potential source of infection is taken...sterilisation, and using 'hot' composting are ways if reducing risks of spreading plant diseases.
That is a good general description Chell, common in my area so I tend to think of it as world wide. Guess it isn't. They are very widely used and their low cost and use of handy materials for the greenhouse make them interesting. Since the plants are usually planted in the ground, compost really can be used as well as fertilizer. file:///home/raspberry/Downloads/horttech-article-p25.pdf
