So if leaving your light on too much grows algae, and marimo is a type of algae, will leaving my light on all day and night result in a faster-growing tuft of marimo?
Light on marimo growout 24/7?

I theory I think your logic works. But I think you could run into the issue of "bad" algae being a problem. Not to mention it could mess up the circadian rhythm of any fish you have in there. Just keep that in mind and try it out.
No fish, just sand and blackworms and a few daphnia for kicks. Got an airstone boiling up the middle to circulate the water and it keeps the tuft rolling. Been leaving the light on except for when we're asleep and the only algae that's growing in the ball. Not much in size, but definitely filling out and looking rounder. It's also a very dark green unlike the parent ball which was a lighter green. No other creatures, just the tuft and the inverts. Seems to be working well.
I don't want to add fish because I want to fertilize the ball well. That means conditions a little less than suitable for vertebrates.

If I am not mistaken, after a period of time, even with the light on, the plant will stop photosynthesizing and begin respirating. After that, you're just wasting electricity. You could put it on a 18/6 cycle. 18 of light, 6 of dark.
Oh. This is true for algae, too? So people with algae scrubbers in their sumps turn their lights off on that for a time every day? I didn't know that.
Algae is a plant and abides by all the same rules and limitations higher plants go by, at a certain point phosynthesis will halt and cellular respiration will begin otherwise it would die as it would have no way of using the sotred chemical eenrgy produced by photosynthesis.knifegill;4718756; said:
And yes people with algae scrubbers usualy have a 18 on/6 off cycle.
