Best Lettuce

I have come to the conclusion that the best lettuce grown in the aquaponic
 system , in Hawaii , is Butter head lettuce.

 I like the small miniature heads . They grow
quickly and they don't take over a lot of the space on the float.
One head makes a big salad for one person.

The mini Butter lettuce comes in 3 colors  green, red and a
kind of mix of red and green.

Butter lettuce  seems to not be too picky
about the weather. It grows  even when it is really hot outside
.
The secret is the  lettuce likes the  cool water in the system, so even when the weather and
sun are hot the plants have cool water circulating around their roots.
