Plants in a gravel aquarium
I would like to grow plants in a 100 gallon aquarium with a gravel filtration system. I cannot grow plants in the gravel because of the filtration system. I have a hallow artificial rock which can be used as a planter when I turn it upside down. I would like to put some dirt in the hallow rock and try to grow some plants.
What kind of dirt/substrate do I need?
Do I need to use plant fertilizer, nutrients, etc?
