Foreground
Picture its place. Understand its size.
Marsilea hirsuta may arrive with clover-like leaves, then develop a different form underwater. Depending on the tank, leaves may become simple or remain divided. Runners spread through the substrate, so the cup's appearance does not precisely predict the mature carpet.
Tropica guide after roughly two months. “+” means the plant may exceed this height; it is not an adult maximum.
The supplied cup · In-vitro
What it needs. And why.
Light
LowKeep the plant lit without aiming for maximum intensity. Lighting duration does not replace the intensity reaching the leaves.
CO₂
LowLow demand does not mean no carbon. Injection is generally optional; growth also depends on light and nutrients.
Nutrition
Roots and leaves contribute to nutrition. Match nutrient additions to the substrate, water and observed growth rather than automatically combining fertilisers.

From the cup to your layout.
A few steps suited to this plant for a good start.
1Rinse off the growing medium
Gently remove the plant from its cup and rinse off the culture gel before placement.
2Divide gently
Prepare small healthy portions without crushing leaves, stems or roots.
3Plant in the substrate
Space portions so light and water can pass between them. Bury the roots while keeping rosette crowns exposed.
Pruning and ongoing care
Leave room for runners and judge establishment by new leaves rather than nursery foliage.
Understanding acclimatisation
An In-vitro cup contains young plants. Shape, colour and size can change after immersion. Watch new growth, remove deteriorating parts and keep conditions stable. Report plants damaged on arrival; acclimatisation does not explain every problem.
