In your grassy areas I'd advise adding some kind of ceiling shaft to a night sky. You can maintain darkness - and add atmospheric moonlight - while not using the harsh light of the sun.
I'd just like to correct you so you understand Botany, plant science(s), phytology, and plant biology (which is a branch of biology) a little better for future reference.
Here is a small example. Not all plants require sunlight or moonlight to coexist in this world. Some plants must be in dark environments, whether they be dry or humid; where as some must be in light environments direct connection to the outside world.
Moss is a great example. Moss can co-exist perfectly within a 100% dark and humid environment with no sunlight or moonlight what-so-ever. It can also co-exist in a light environment but once again it must be humid.
But lets add a twist, let us add in a light source. In my levels case for moss, a torch. Say you could light this torch non stop (which is not likely) the torch would actually slowly kill the moss due to the fire from the torch gathering the air around it, making the area dry and not humid. Now if the torch is only lit for awhile; usually half a day is the length of a torches life, then it wouldn't be able to kill the moss. Now lets put the torch on one side of the room and the moss on the other. Depending on the gaps for air within the walls the moss could co-exist with an infinite torch.
Artificial lights are the same way, light gathers heat, it depends on how long the light source is on and the type of light it is, the effective radius from the moss and the environment the moss is in to how it will affect the moss or how the moss will grow.
Many plants can co-exist in the same way.
Nature *can* exist with or without natural or artificial light depending on the type of botany we are dealing with.
The *grass* you see is moss on brick, actually.
The environment is closed in and since we cannot physically enter the space within the game we cannot determine the environmental effects such as humidity, breezes or the actual temperature of the environment, and thus we cannot discertain what plants could grow in that environment 100% which is why I stick to the basics of botany.
In effect, the level is as realistic as I can make it when it comes to the plant life

Though I will say that some food sources are above the surface in literal terms, so the plant can obtain it's source of food if required from an above area via links, but still co-exist in the dark environment alone. Moss just needs humidity to survive so it can exist miles below the surface as long as it's still humid

But thank you for your comment. It was productive in the effect that it made me refresh myself to get my environment correct since I am aiming for realism.
Also just wanted to say, I'm not trying to be a douche, I just wanted to teach you in the concept of the plant life I am using so you can take it as advice or just take it as constructive criticism and throw it away, I am sure you are a nice guy; though not a biologist
