Journal January 6, 2016 - Our mild winter has vanished.

December was the warmest December locally since they began keeping records, and warmer by several degrees!  It was t-shirt weather on Christmas, even a local golf course reopened for a few days.

That said,  our mild winter went poof, literally overnight. The night temperatures have been from below zero to low single digits and the ground is now frozen solid. The day temperatures have been in the teens, today we have a heat wave with the temperature at 25 degrees. I braved the cold to get a pruning tool from the tool shed and thought I'd check the greenhouse, even though it is empty. Good grief, 85 degrees in here! Turn on some music, grab a chair and let Old Sol warm these creaky old bones. It felt so good that, Sol cooperating, I may make it a daily ritual.


The Gentilina lettuce is coming along nicely now.

'Gentilina' is an premium Italian lettuce variety, usually found in mesclun mixes which produces an open loose head of slightly savoyed, crinkled and ruffled leaves.
Lettuce 'Gentilina' is good for baby leaf use or can be grown to full maturity. It holds well in summer heat and has good resistance to bolting. The rich green colour and nice texture make this a premium salad selection.

It is one of the easiest, trouble free lettuces you can grow. It's a cut-and-come-again, that is, if you pick the outer leaves, the plant will continue to grow. Given the right conditions, this type of lettuce will produce leaves for three months or more. 30 days for babyleaf or 55 days to maturity. 


It takes a while for the roots to develop, but once they do the plants really put on a spurt of growth.


Today I refreshed the nutrients and changed the tanks.  One of the nice things about aeroponics is how clean the process is.  The photo above shows the used nutrients, they look as crystal clear as they did the day I placed them in the system.

About how often do you need to change the tank and refresh the nutrients? Have you ever considered using aquaponics?

For lettuce I refresh the tanks every two weeks, it only takes 2.5 gallons to refresh. I have no interest in aquaponics, hydroponics is a much cleaner process, plus, I can start and stop whenever I wish with no need to maintain fish. During the summer I hardly use hydroponics at all as I grow in the greenhouse. In the greenhouse I use autopots with nutrients.
