This report describes the environmental conditions used to grow containerized 1+0 spruce seedlings at Red Rock Research Station. Temperature, nutrition, light and moisture are discussed. Seedlings are germinated at 20°C in March and gradually lowered towards the end of the growing season. They are fertilized with 20-8-20 at concentrations ranging from 30 to 85 ppm N. Photoperiodic lighting is provided during the early part of the growing season to prevent budset. After photoperiodic lighting ends, blackout, rather than nutritional and moisture stress, is used to induce budset.
