Susan, I have a very simple set up for seedlings. Don't use lights here, just a south
facing window or rather windows. The plants do get a bit on the spindly side, but
they grow out of that really fast once planted in the ground in the spring.
The pots are saved pint cottage cheese cups that have been microwaved with the
potting soil in them at a high enough temp to kill bacteria and fungus. So far that is
working as I don't have fungus gnats or damp off. So I guess you could say I
recycle with the cups.
And the cups do get a bleach wash before
microwaving them.
Many of the seedlings will be pretty garden plants, and maybe a few that are
something to register. I have not registered any yet. Been doing this for five years
or so, and if the few that I am watching do well next season, I will register some.
Last year I had over 2500 seedlings in the house over the winter, and this year,
around 1000. I do put several seeds in each cup, because if I didn't, I would not
have space for them. Trying to cut down on the work, and need to reduce the
number even more next year. Now, If I would just listen to myself.
Anyway, I love doing this, and I love the flowers.
