Refractory period: lights only on when solar light was below 300 W/m 2 for at least 10 mins. Total DLI: 26.8 mol·m-2 ·d-1 at 1.5 m above the greenhouse floor (note that the average total DLI at 0.5 m above the floor was 23.3 mol·m-2 ·d-1, and at 2 m above the floor was 29.5 mol·m-2 ·d-1)* smartPAR Control
The Experiment: Light Intensity Impact on Yield and Secondary Metabolites. Using the training they received in graduate school (Allison is a graduate of Clemson University with a Ph.D. in Plant and Environmental Science and Josh a graduate of Purdue University with a M.Sc. in Horticulture), the team developed a protocol to evaluate the impact of light intensity on plant growth and development.
A dull winter’s day with heavy cloud cover and a short day-length may see a DLI inside a greenhouse as low as 3 mol/m-2/day. On the other hand, a bright, clear, sunny mid-summer’s day with a long day length of 18 hours can create an average DLI of 35 mol/m-2/day inside a greenhouse.

as how to make and process them. That said, as explained in Chapter 3, the requisite material properties that are to be optimized cannot be measured by the usual quasi-static measures of mechanical behavior.However, even at lower strain rates, conducting mechanical tests at small scale—that is, at the microstructural level, on the order of nanometers or microns—will likely shed light on ...
Jan 30, 2020 · The grow light’s power cord is connected to the power meter and then the power meter is connected to an electrical socket. The power meter then tells how many watts the lamp draws. Dividing the light output with the number of watts tells us how efficiently a lamp runs, or rather, what it’s efficacy rating is. Efficacy often shows quality.
