I want to try putting some of my plants in pots. I have a gravel & sand substrate, low lights and no CO2
I'd like to have root feeding plants like amazon swords or wisteria, and am struggling to find root tabs over here. There are some but incredibly expensive. Also cant find osmocote or any of those "home made" ingredients.
So my plan: small unglazed terracotta pot, well drained with gravel in the bottom, potting soil, then a gravel cap on top.
I also like the idea of being able to move plants and clean substrate etc.
Would this work? What would I need to watch out for?
