season extension

By Jan Steinman

Straight table legs get in the way and are fragile without lots of bracing. A pedestal base with 45 and 30/60 geometry uses 40% less lumber than a 6-legged table, is self-adjusting on un-level ground, and is much stronger than...

Use salvaged windows and materials to construct a mini-greenhouse for season extension. These cold frames can be used to warm soil before planting directly in the ground, create a micro climate for seedlings and starts, overwinter dormant plants, and more.

A "sweat box" style germination chamber built using readily available parts and a broken chest freezer that provides humidity and temperature control. Early season germination can be inconsistent without a closely controlled environment for starting seeds. Commercial greenhouses use...

A seed germination chamber using a broken upright freezer. I got the idea from DGrover's "Sweat box" Germination Chamber: http://farmhack.org/tools/sweat-box-germination-chamber. I added onto their design by adding lighting, air circulation, a heat source and temperature/humidity gauges. This is a functioning...

Heated greenhouse tables serve two main purpose on the small market garden veggie farm. First, it offers a place with a fairly constant temperature to ensure high germination rates. Not too unlike the Sweat Box Germination Chamber (http://farmhack.org/tools/sweat-box-germination-chamber),...

In the winter and early spring, seedlings in the greenhouse need extra protection from frost. Bench heating systems can provide the necessary bottom heat but without covering the bench, much of the heat is lost. Farmers typically cover their benches...

This is the first phase of a project to build a solar-powered automated greenhouse ventilation system. Farmhack NYC will also host a meet-up design session for this project.
