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.
