How much light does Wendt Cryptocoryne need?

Medium light, around 30–50 µmol·m⁻²·s⁻¹ of PAR. Watts are not comparable between fixtures; PAR is. If the manufacturer does not publish PAR, pick one band lower than the tank depth suggests.

Does Wendt Cryptocoryne need CO₂?

It is optional. Marked "optional": with CO₂ it grows faster and tighter, without it still does fine.

What water does Wendt Cryptocoryne want?

22–28 °C, pH 6–7.5, 2–12 dGH. At 10 dGH wide it is one of the more forgiving ranges.

How fast does Wendt Cryptocoryne grow, and where does it go?

Growth rate: slow. Placement: foreground / midground. Substrate: substrate required, reaching about 10–25 cm. Difficulty: beginner.

The beginner crypt, shade-tolerant and happy in soft water, and it may melt right back after a move before growing again.

Growing notes

1A move, a large water change or a temperature swing often triggers crypt melt; as long as the rhizome is still firm it leafs out again in one or two months.
2Once planted, leave it alone; repeated moving keeps it permanently in recovery.
3It survives low light but colours and broadens best under medium light, and stretches its stalks when the light is too weak.
4It sends runners underground; cut the daughter plant free once it carries three or four leaves.
5New leaves pale when iron is short, and an iron-bearing liquid or root fertiliser greens them in about two weeks.
