mostly, it just has sword fern in the bottom which i know is safe but there are a few foreign weeds though. If you may notice though, the entire cage is shady, maybe i shall just remove like the front third of the roof. but yea. just a few hours a day, maybe ulitmately like the whole time im at school which takes 7 hours but i think thats too long, i think i may also have an extra slot in my houses sprinkler system that i could use to rig up one or two of those fine mist sprinklers.
