If you leave them long enough they will grow to larger sphere's the underground man should explain that.
Just leave it on overnight
Provided the light is strong enough and is on for long enough Duckweed should grow well in artificial light. I do hope you are not calling a small tank a 'Pond'.

There is no minimum or maximum for how long you can let something grow. You can leave it in the incubator for as long as it is alive and continues reproducing.
As long as the roots are in the ground the plant will grow towards the light.
12 hours of light 12 hours of dark
anytime as long as you ave water and light
Until they grow up and leave home :(
To stop putting mascara on them and, leave them alone and let them grow.
30 minutes to an hour.
