Water level indicator III, P6230 (for Hydroponic Pots) makes water checks in larger hydroculture planters simple and clear. Its MIN, OPT and MAX scale rises and falls with free water in the reservoir, so you can see the available reserve without lifting the plant or guessing. This model features a stable base and approximately 30.4 cm overall height and is selected for planters or compatible liners with an actual planting depth of approximately 21 cm. It supports a calmer, repeatable care routine, provided that the actual planting depth is measured first and the float is left free to move.
Reads the reservoir · not moisture
See the level without lifting the plant
The float follows free water in the watertight reservoir and transfers that movement to the visible scale. This provides a consistent reference without dismantling the planter.
- Choose III by its actual fitting depth: 21 cm.
- For normal care, OPT is the usual refill target.
- Refill frequency must be adapted to the plant, season and conditions.
It is not a moisture sensor. The reading refers only to free water in the reservoir.
Choose by actual measurement
Planting depth is clearly distinguished from the overall height of the product and planter.
A steadier routine
MIN, OPT and MAX replace blind estimation with a visible point of reference.
In the pack

FittingDepth, overall height and compatibilityCorrect measurement prevents choosing the wrong model.
Where III fits correctly
Planting depth is the functional measurement inside the system. It is not necessarily the same as the indicator's overall height or the decorative planter's external height.
21 cm
for planters or compatible liners with an actual planting depth of approximately 21 cm.
7 × 7 × 30.4 cm
Overall size helps check available clearance, but it does not replace measuring the planting depth.
Medium hydroculture planters
Designed for larger hydroculture planters than the slim Indicator II range.
Check the base and free travel
Do not choose it merely because the outer planter is 30 cm tall. The key measurement is an internal planting depth of about 21 cm.
Dimensions are nominal/approximate. For an existing hydroculture planter, measure the actual internal space before purchase.
Use & readingMIN, OPT and MAX without a rigid scheduleThe reading follows free water — not substrate moisture.
Read MIN, OPT and MAX without guesswork
The scale follows the level of free water in the watertight reservoir. It does not measure moisture in LECA, Pon or another substrate, and it cannot assess root condition.
The reserve is low
Observe the plant's water use and plan the next refill. There is no single fixed interval for every plant and season.
The normal refill target
Add water slowly and stop at OPT unless the specific plant or system instructions require a different approach.
A larger temporary reserve
Use it selectively, for example before a period away. It is not automatically the permanent level for everyday care.
Important: III is a mechanical water-level indicator. If the reading remains still while the amount of water changes, first check for mineral deposits, residue or an obstruction around the float.
Four steps to a clear reading
Correct fitting and free movement of the mechanism matter more than filling quickly.
Measure the depth
Confirm that the hydroculture planter matches the 21 cm fitting depth.
Fit the indicator
Position it vertically so the base or float reaches the reservoir without being forced.
Check free movement
Before completing the installation, make sure the reading rises and falls without friction or sticking.
Fill slowly to OPT
Add water gradually, watch the scale and stop at the chosen target.
Technical & careModel, size and cleaningThe essentials for correct fit and free movement.
III · P6230
Hydroculture water-level indicator with a MIN, OPT and MAX scale, selected for a fitting depth of 21 cm.
7 × 7 × 30.4 cm
Overall dimensions are approximately 7 × 7 × 30.4 cm; this overall height is not the same as planting depth.
For larger hydroculture planters
It features a stable base and approximately 30.4 cm overall height.
No improvised alterations
No separate extension is required for the stated fitting depth. Do not modify or cut the indicator body.
Free movement keeps the reading reliable
Mineral deposits, fine granules or organic residue can restrict the mechanism.
Remove loose residue without high heat or aggressive cleaners.
The reading should move smoothly and return without sticking.
Clean when movement slows or mineral build-up becomes visible.
Frequently asked questions
Short answers on fitting, correct readings and cleaning.
01How do I choose the correct model?
Measure the actual internal planting depth of the liner or cultivation pot. III is intended for planters or compatible liners with an actual planting depth of approximately 21 cm.
02Is overall height the same as planting depth?
Not necessarily. This model is selected for 21 cm, while its overall size/format is 7 × 7 × 30.4 cm.
03Does it measure moisture in the substrate?
No. It displays the level of free water in the watertight reservoir. It does not measure moisture in LECA, Pon or soil.
04Should I always fill to MAX?
No. OPT is the normal refill target. MAX is used selectively for a larger temporary reserve, depending on the plant and conditions.
05How often should I refill?
There is no rigid interval that suits every plant. Follow the falling reading together with season, temperature, light and the water use of the specific plant.
06Why is the reading not moving?
Remove and rinse the indicator, then check for mineral deposits, fine granules or residue obstructing the float. Refit it without forcing it.
07Can it be used in a normal soil pot?
It is designed for a system with a free-water reservoir and the correct fitting position. It does not work as a soil-moisture meter in a conventional pot.
08What is included in the pack?
One Water level indicator III (P6230). The planter, liner, LECA, plant, outer pot and nutrient products are sold separately.
