Excel is not always the best choice. It can harm plants. Co2 is much better. Laying the plants down horizontally so that they grow new stems from each node works well. I sometimes simply float them that way they gain co2 from the air.

High CO2 would work but the 24hr light period won't. In my experience plants only need 6-8hrs of good light. If you give them 24hr light I think you will just get algae.

yea with 24hr lighting you'd get some crazy algae going. Though it'd be an interesting experiment if you had a UV sterilizer or some type of algaecide + high CO2 + 24hr light.

In the long run, I think you would severely damage or kill the plants if the lights were on 24/7.

Plants need a time of rest to complete photosynthesis.

I would go with what other people have said and use high light, high co2. If you already have a pressurized system you're good to go, otherwise put a bunch of DIY co2 reactors on.

I've noticed that many plant species I've kept point their leaves up towards the surface at the end of the day, even while the lights are on. I've read that this is a sign that they're pretty much done with photosynthesis for the day, and further light doesn't do much. That being said, I wouldn't do a 24 hour light period.

It should be mentioned that not all plants need a rest period. Some plants do fine with 24 hours of lighting.
Can you give some examples? I'm curious what plants will do well under 24 hours of lighting (and why?)

In jr high , we grew fruit and vegetable seedling under 24/7 lit incubators for 3 months.

FYI, Marijuana plants grown in Green Houses receive 24/7 lighting.

Most plants won't do well with with 24hr photo period. Almost all stem plants grow like weeds
