Building a Germination & Healing Chamber for Seedlings and Grafted Tomatoes

Learn how to build a small-scale germination chamber using repurposed materials and readily available off-the-shelf parts to more successfully start seeds and improve seedling production. The table top chamber fits up to seven starter trays and uses a temperature controlled water bath, wide-spectrum interior light, and controlled humidity to provide an ideal environment for seed starting and graft healing. Richard Freudenberger, Living Web Farms’ Energy and Resource Coordinator explains construction techniques, insulation, heating, lighting requirements, and humidity control using an inexpensive microprocessor.
