A planted tank is gardening, in water

Everything here is written by people who keep tanks — how plants actually behave, why the third month is when scapes fail, and what to do about the algae that arrives in week two.

We have no shop, and nothing here is sponsored

Glassmeadow does not sell plants, hardware or substrate, and does not take commission on anything we mention. That is the whole editorial policy. It means we can say a popular product is not worth buying, and occasionally we do.
