LED UFO Grow Lamp trial
So far the trial of the UFO LED grow lamp and homemade aeroponic unit seems to be percolating along nicely. I am quite impressed with the light, and the plants seem to be responding as I hoped they would. If I can remember to do so I will photograph the plants weekly to record the progress.
The temperature in the growing area is running from 70 to 80 degrees, with the humidity averaging 25 to 35 percent. I know that is a little high for lettuce, but I spend a good part of my day in the growing area, and I don't like being cool...
The lettuce varieties I am using, Slo-Bolt and Capitan, are both greenhouse varieties, and both can tolerate extremes of warm and cool temperature.
Capitan Lettuce - Bibb Butterhead
62 days. This Dutch greeníhouse lettuce is adapted equally well to greeníhouse or garden. 'Capitan' was judged the best Boston-type lettuce in the l983 Rodale Research Center variety trials. Excellent heat and cold tolerance plus resistance to lettuce mosaic virus. The 5 oz. loose heads have a light green color, excellent taste, appearance, and yield. Nice buttery flavor.
Slo-Bolt - Looseleaf Lettuce
48 days. [Introduced 1946.] "Grand Rapids" type lettuce with good heat tolerance. Excellent choice for Southern gardens or greenhouse use. Leaves are bright green and ruffled
In the photo above the center plant is the Slo-Bolt, and the plants on either end are Capitan.
My aeroponic unit is working perfectly mechanically, and I am feeling sorry I have not used it before now. I am not sure it will live up to all the hype that has been published concerning them though. If it does, I will not mind being pleasantly surprised.
