Customizing Crop Foliage Color With LEDs: Ornamental Crops
Do you find that your purple fountain grass (Pennisetum setaceum ‘Rubrum’) crop is often green to light purple? What if we told you there is a quick solution to enhance and darken the foliage of purple fountain grass or other floriculture crops? In this second article of a four-part series highlighting the multiple uses of high-intensity light-emitting diodes (LEDs), we will discuss our research methodology and findings for enhancing the foliage color of ornamental crops with end-of-production (EOP) supplemental lighting (SL) in the greenhouse. Many ornamental crops that greenhouse and nursery growers produce vary in size, shape and color. These variables are often influenced by the growing environment. For example, leaf color (intensity, distribution or both) of ornamental crops such as purple fountain grass is a key component that often influences the consumer’s perception and ultimately an impulse purchase. The red or purple pigmentation of purple fountain grass leaves is […]

Selecting Fertilizer Rates For Several Spring Bedding Plants
Fertilizing bedding plants can be difficult due to the differing needs of the large variety of plants that we grow. Many operations do not grow enough of any one crop to cater the fertilizer specifically for each crop. Therefore, grouping crops with similar fertilizer requirements and having two to three fertilizer strengths available is a practical way to ensure plants are getting the fertilizer they need. With many new plant varieties on the market, we wanted to conduct a trial at Cornell University to determine best fertilizer rates for several common bedding plant crops. 22 Bedding Plants Studied To Establish Fertilizer Rates Plugs and rooted liners of 22 crops (Table 1) were transplanted into 4-inch (500 mL volume) round pots with a commercial peat/perlite based substrate. The plants were grown in a glass greenhouse at Cornell University during the spring season at a spacing of one plant per square foot. Heating set […]

The Future Of Greenhouse Structures
We’re not predicting the end of the Quonset or big gutter-connect ranges. We do, however, believe you will see a dramatic change in the ways some traditional structures work, where greenhouses are built, or even what is considered a “greenhouse” in the future.
