The owner of my former minnow business shut it down this year. He left me the 8'x16'x4'deep minnow tank so I tore it down and rebuilt it as a 10'x20'x20" seedling growout tank. It's made of pressure treated lumber and 3/4" plywood, and a polyethylene liner. All of the plants and many more were in a 4'x7' tank two weeks ago. They seem really happy to have more room and bigger pots. They are all seedlings of N. 'Ostara' and open pollination. The last 2 pics are of a nightbloomer seedling that normally makes cup shaped or flat blooms. I don't know why it made one bloom that opened past flat. I wish all of its blooms were like the last one.
