As most of you know, I am not a 'normal' houseplant person. I am almost exclusively a tropical gardener, and am fortunate enough that I can grow many things in my yard. What I can't, I grow in my greenhouse. But there are some things that I really don;t want to put in the greenhouse, either because they were get lost, or because the winter climate, even though I keep it warm, would still not be 100% beneficial for the plants. So I am building another indoor habitat for these plants. Its not really a terrarium, because its not enclosed. Its not really a vivarium, because I will be keeping no animals. Its more like a riparium, a planted aquarium, but its not all water. So I call it an indoor houseplant habitat.
Its 75 gallons, 50 inches long, 21 inches deep and 21 inches tall. I have put in the back ground (large cork bark slabs I had laying around) and the false bottom (a thick layer of aliflor and pea gravel) that holds water for recirculation, I have run the hoses for the water features, and covered that with landscaping fabric to separate the water from the soil substrate. Later today I will start filling in with sphagnum moss and soil substrate, install the water features and decorations, and then the fun really starts: adding the plants I have collected and so far been growing in a 10 gallon holding tank! Still have to go get my lights, but thanks to my daughter, I have all the fixtures already. I did not have to buy any of the things that I am using to make this except the wood pieces. I had it all laying around the greenhouse, my daughter gave me the aquarium. I even already had the pond pumps from past water setups. So its a pleasure to repurpose stuff I already had into a new idea for growing plants in my house.
This is the set up so far. The tank
