Backyard Springtime Nature in New Jersey.

Birds of the Day — Brown-headed Cowbird, House Finch, Northern Cardinal, Pileated Woodpecker, and Eastern Phoebe. I haven’t seen the Pileated Woodpecker in my yard for some time. I’ve heard it working on the neighbors trees looking for grubs. The Eastern Phoebes are back to just feeding the two young chicks in the nest.

I got part of the yard mowed before it started raining. Time-lapse video recorded using a Garmin VIRB-360 camera

Now I have rats or mice running around on the patio. I don’t want to put poison out, but the neighborhood cats are going to have to do a better job.

Indoor Springtime Hydroponic Farm.

Although many of the plants started in January (or last fall) in the AeroGarden Farms are nearing the end of their lifecycle, I am still harvesting tomatoes and strawberries. The strawberry plants will be transplanted outside into a Grow Tower system. This will be an experiment since some of these plants came from the outdoor Grow Towers last fall. I’m still waiting to see if the Hot Peppers and Ground Cherries will ripen indoors. They are being slow. I am not sure if this is a temperature or amount of light issue.

Daily Electric Energy Used (51.6 kWh) from Sense Home Energy Monitor and Daily Solar Electric Energy Produced (8.1 kWh) from SolSystems and Locus Energy. Lots of rain and clouds. A deficit of 43.5 kWh.

Weekly Electric Energy Used (403 kWh) from Sense Home Energy Monitor and meter readings. Weekly Solar Electric Energy Produced (310 kWh) from SolSystems and Locus Energy. A deficit of 93 kWh. I hoped to go net positive this week, but too many cloudy and rainy days. Numbers corrected by meter readings for the time that the Sense monitor was offline.
