Here's pictures of the outdoor adult tilapia tank, with grow trays on

Those tanks a black so they will retain some heat. I'd guess the
portable patio heater I mention before will supplement the heat over
night.

Those ferns are cold sensitive. It doesn't take much cold to kill
them. If they are in water, then you are drowning them. They don't
need a lot of water (tropical). You could cover them with burlap on
cold nights

The ferns are in a grow bed that have 'grow media' below the pots so
they aren't drowning but are getting a constant supply of fish
fertilizer. The Boston fern is gigantic and has doubled in size since we
bought it this spring, and it'll be moved inside when we move the fish
and grow beds inside for the winter. Most all the plants in the grow
beds are there to help filter the fish water. We've experimented with
different plants to see which one like the system and which ones not so
much.

I thought you were growing food plants (winter varieties will do good)


That grow bed is at the end of the season and we've been growing duck
weed and some water plants in them. We have another grow bed above the
juvenile tank that has strawberry plants and fresh basil growing in it
right now. During the summer we move everything out to the garden area,
so there's not much in the green house grow beds right now.
