6 pages., Via online journal., Strawberry (Fragaria ×ananassa) and caneberries (Rubus sp.) are popular crops that can bring revenue to farms and may improve farm profitability. High and low tunnels can bring a number of benefits to growers, including season extension and improved berry yield and quality, as well as management challenges. Few studies in the literature report directly on grower experiences using tunnels. We report the results of interviews of 10 independent growers who use tunnels to produce strawberries and caneberries. The results echo previous studies finding improved yield and quality, and highlight benefits and challenges around pest, weed, and nutrient management. One novel finding is the role of season extension in creating marketing opportunities. Interviewed growers caution of a learning curve and the need to start on a small scale and grow gradually. Future focus for research should include improved ventilation and mechanization.

6 pages., Via online journal., Electric lamps are widely used to supplement sunlight (supplemental lighting) and daylength extension (photoperiodic lighting) for the production of horticultural crops in greenhouses and controlled environments. Recent advances in light-emitting diode (LED) technology now provide the horticultural industry with multiple lighting options. However, growers are unable to compare technologies and LED options because of insufficient data on lamp performance metrics. Here, we propose a standardized product label that facilitates the comparison of lamps across manufacturers. This label includes the photosynthetically active radiation (PAR) efficacy, PAR conversion efficiency, photon flux density output in key wave bands, as well as the phytochrome photostationary state (PSS), red/far red ratio, and graphs of the normalized photon flux density across the 300–900 nm wave band and a horizontal distribution of the light output.
