    Seed Germination/Early Growth Chamber

    Seed Germination/Early Growth Chamber

    A seed germination chamber using a broken upright freezer. I got the idea from DGrover's "Sweat box" Germination Chamber: http://farmhack.net/tools/sweat-box-germination-chamber. I added onto his design by adding lighting, air circulation, a heat source and temperature/humidity gauges. This is a functioning concept that is being tested right now, and there are still issues to work out. Such as preventing excessive temperature and humidity levels as well as other concerns. So far the expense is about $150 (not including cost of freezer), nominal compared with a manufactured growth chamber, thus enabling small farmers/gardeners the ability to reliably start quantities of seeds early and extend their season.

    Ground-Driven PTO Forecart converted from antique tractor

    Ground-Driven PTO Forecart converted from antique tractor

    This ground-driven PTO forecart is made out of a CASE VC tractor. We split the engine off of the rear end, and built the rear end up into a cart, adding a deck, tongues, a seat, and a railing. Generally, a forecart is used in between a team of draft horses and a piece of farm equipment and includes a place for the teamster to stand or sit while operating the machinery. For us at the Northland Sheep Dairy that means a 14 ft rotary tedder (tested and functional) but it could be used for many different PTO-driven pieces of equipment--perhaps even combines and balers. This project was undertaken at the Northland Sheep Dairy by Donn Hewes.

    Rocket-clave- A wood-fired autoclave

    The rocket-clave is a wood-fired autoclave. The rocket-clave was designed in order to reduce fossil-fuel consumption (specifically propane) in the production of edible and medicinal mushrooms.

    Outside Air Exchange Control

    Outside Air Exchange Control

    This tool demonstrates the use of two thermostats to provide a control system for an air exchange fan that draws cold outside air in to cool a storage room for winter crops. The control essentially provides a differential temperature control which may also be applicable to other processes (curing, solar hot water, etc.)

    Sweat Box Germination Chamber

    Sweat Box Germination Chamber

    A "sweat box" style germination chamber built using readily available parts and a broken chest freezer. Early season germination can be inconsistent without a closely controlled environment for starting seeds. Commercial greenhouses use similar systems but the cost can be prohibitive for the small vegetable grower.
