See the water level at a glance and water with greater confidence.
Fitting: 21 cm base · up to 52.75 cm with extensions · Scale: MIN · OPT · MAX
Water level indicator IV, P6240 (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 removable scale, wide shaft and optional extensions and is selected for a 21 cm starting planting depth, with up to five optional extensions of approximately 6.35 cm each. It supports a calmer, repeatable care routine, provided that the actual planting depth is measured first and the float is left free to move.
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.
Follow the changing level without lifting the liner or disturbing the plant.
Planting depth is clearly distinguished from the overall height of the product and planter.
MIN, OPT and MAX replace blind estimation with a visible point of reference.
One water-level indicator, model IV, code P6240.
The cultivation pot or liner, growing medium, outer planter, plant and nutrient products are sold separately.

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.
for a 21 cm starting planting depth, with up to five optional extensions of approximately 6.35 cm each.
Overall size helps check available clearance, but it does not replace measuring the planting depth.
Adapts to different depths without replacing the complete indicator.
Extensions are sold separately and are designed only for model IV. Do not improvise with unrelated tubing.
Dimensions are nominal/approximate. For an existing hydroculture planter, measure the actual internal space before purchase.
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.
Observe the plant's water use and plan the next refill. There is no single fixed interval for every plant and season.
Add water slowly and stop at OPT unless the specific plant or system instructions require a different approach.
Use it selectively, for example before a period away. It is not automatically the permanent level for everyday care.
Correct fitting and free movement of the mechanism matter more than filling quickly.
Confirm that the hydroculture planter matches the 21 cm base · up to 52.75 cm with extensions fitting depth.
Position it vertically so the base or float reaches the reservoir without being forced.
Before completing the installation, make sure the reading rises and falls without friction or sticking.
Add water gradually, watch the scale and stop at the chosen target.
Hydroculture water-level indicator with a MIN, OPT and MAX scale, selected for a fitting depth of 21 cm base · up to 52.75 cm with extensions.
Overall dimensions are approximately 8.3 × 8.3 × 31.5 cm; the wide shaft provides reservoir access and allows suitable nutrients to be used according to their instructions.
It features a removable scale, wide shaft and optional extensions.
The base version starts at a 21 cm planting depth. Up to five compatible extensions of approximately 6.35 cm each can be added, only for model IV.
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.
Pair it with a suitable liner or cultivation pot, clean growing medium and a watertight outer planter.

Measure the actual internal planting depth of the liner or cultivation pot. IV is intended for a 21 cm starting planting depth, with up to five optional extensions of approximately 6.35 cm each.
Not necessarily. This model is selected for 21 cm base · up to 52.75 cm with extensions, while its overall size/format is 8.3 × 8.3 × 31.5 cm.
No. It displays the level of free water in the watertight reservoir. It does not measure moisture in LECA, Pon or soil.
No. OPT is the normal refill target. MAX is used selectively for a larger temporary reserve, depending on the plant and conditions.
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.
Remove and rinse the indicator, then check for mineral deposits, fine granules or residue obstructing the float. Refit it without forcing it.
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.
