I’m new to the forum. I’ve been growing aquatic gardens & keeping fish for about 3 months now. I’ve had some very satisfying and exciting results so far. I’m very new to gardening with respect to the emphasis on the research portion. I learned a lot from the aquarium forums, and so naturally here I come! In your best terms, and to a layman like myself, how do you compare aquarium gardening to plant keeping ? More specifically, I’d like advice on soil composition. Nothing too extreme here; just garden soil, sand, gravel/stone is what I plan on working with. I have an idea to put gravel at the bottom of a potted ZZ planter, and then build the substrate upwards from there with a sand & garden soil mix. In my experience so far keeping plants, the soil seems to be lacking oxygen. Attached is a photo of seeds I plan on propagating soon & some planters I currently care for / adopted from friends. I will be using the seeded plants hydroponically in my aquarium gardens after they have established.
