  1. Some tree nursery’s have ” instant orchard” trees at premium prices, they claim you can pick fruit, berries and nuts right away. The question is do these trees represent real value vs cost? I live in Maine and the climate is pretty tough, we are keen on our preps and believe the time is now and so a Hazelnut tree 1.5″ @ 6ft is $65 vs a instant orchard 2-2.5″ @7-8ft is $129 that theoretically would yield right away.I have the money but is their claim overstated? Further,the fact that some of these orchards are in the south(Georgia) contribute to the survival of plants that can grow in zone 4-5,, does that contribute to their survival because they have not been exposed to our severe climate? FYI we have 25 ac. pigs, chickens, extensive gardens, fairly permaculture.

  2. to the person worried about having a sustainable water filter. It is possible to make your own filter. If you know how to make and fire clay pots you can mix things like coffee grounds, or rice husks, fine sawdust, etc. into the clay. When you fire it that organic matter will burn out. That will at least give you a reusable filter providing clean water you can boil. To make it antibacterial brush the inside and outside with colloidal silver (you’ll need to learn how to make that too). These filters are actually sold in third world countries like Cambodia

  3. @Doug – Great link to the ceramic filter videos.

    @Jack – What about the shelf life of unused filters? I’m interested in the LifeSaver products, but the manufacturer lists their filters as having a 3 year shelf life in the unused condition. I hesitate to include this product in long term preps because I would hate to have to throw out unused filters every three years in the probable event that I won’t need them.

  4. A better, homemade, water filter is also widely used in the 3rd world, slow sand filters. They require pre-filtering of turbid water, but kill all biologicals.

    Technical specs for making one:

    Slow sand filters have a number of unique qualities:

    Unlike other filtration methods, slow sand filters use biological processes to clean the water, and are non-pressurized systems. Slow sand filters do not require chemicals or electricity to operate.
    Cleaning is traditionally by use of a mechanical scraper, which is usually driven into the filter bed once it has been dried out. However, some slow sand filter operators use a method called “wet harrowing”, where the sand is scraped while still under water, and the water used for cleaning is drained to waste;
    For municipal systems there usually is a certain degree of redundancy, it is desirable for the maximum required throughput of water to be achievable with one or more beds out of service;
    Slow sand filters require relatively low turbidity levels to operate efficiently. In summer conditions and in conditions when the raw water is turbid, blinding of the filters occurs more quickly and pre-treatment is recommended.
    Unlike other water filtration technologies that produce water on demand, slow sand filters produce water at a slow, constant flow rate and are usually used in conjunction with a storage tank for peak usage. This slow rate is necessary for healthy development of the biological processes in the filter.[1]:38-41 [2]

  5. My favorite TSP quote of all time:
    “… the solution is always fighting and yelling and screaming and waving a sign. And that shit doesn’t feed you.”

    Right on Jack!
