The plants will have a photoperiod of 12 hours, with an intensity of just about 5,000 foot candles. That intensity is not necessary, however, it should not harm the plants.
Christmas is forecast to be warmer here in upstate New York than it will be in Los Angeles. The greenhouse is still open, with the forecast for the warmer temperatures to continue into next week, it will probably remain open into January.
I am not complaining, it could stay this way and I would not mind at all.....

The Gentilina lettuce seeds have been placed into horticubes to further develop prior to being placed into the aeroponic systems.
In my opinion, horticubes are far superior to rockwool, in that they do not have to be pH adjusted and are almost impossible to over water.
That said, I find the pre-punched holes in the cubes are far too big for tiny seedlings, like lettuce. To overcome this, prior to placing the seedlings in the cubes, I use the end an artist's brush to punch a small hole on the bottom of the cubes for the seedlings. Using tweezers and the artist brush I place the seedlings in the holes and "tuck them in."
The cubes are fine as is for larger seedlings like cucumbers, but work better for me using the above method for small seedlings.
Once tucked in, the seedlings are placed under 2 24" T5 grow lights until they have a few true leaves and roots showing from the cubes.
Using the 1/4" tube I can exhale CO2 into the tray a few times a day to help the seedlings along.

This illustrates the importance of having fresh seed, for lettuce in particular.

Today I started seeds for Gentilina lettuce to be grown in two of the aeroponic units. It was necessary to purchase seed, so I placed an order with Alisorganics.com. The seeds were received yesterday, however, the sell by date is only three weeks away.
That is normally not a problem, but with lettuce is it definitely will be a problem. The seeds were placed in the refrigerator in an attempt to prolong their viability.
