Neptune Hydroponics CANH3 is a compact 30 W plant heating cable featuring a 4-meter heating section. It is designed to heat root zones, propagators, seedling trays, and stations used for seed germination and rooting cuttings.
Thanks to its low power output and 4-meter length, the CANH3 model works well in smaller growing spaces where localized and even heat distribution is needed. An additional 2 meters of non-heating cable makes it easy to connect the device to a power source.
The proper substrate temperature is particularly important during the early stages of plant development. A substrate that is too cool can impair germination and rooting in young seedlings.
The Neptune Hydroponics heating cable delivers heat directly to the selected growing area. It can be used under a propagator, in a seedling tray, or in an area designated for holding containers with young plants.
The CANH3 model features a 4-meter heating section, making it easy to use in a relatively small space. The cable can be arranged so that heat is distributed evenly throughout the selected area.
In addition to the heating section, the unit includes a 2-meter non-heating cable. This allows the power supply section to remain outside the heated area and facilitates installation in a grow box, propagator, or greenhouse.
With a power rating of 30 W, the CANH3 is primarily designed for localized heating of the root zone. It is not intended for heating an entire room.
The cable can be used, among other things, for:
The heating section is designed so that heat is emitted along the length of the cable. The cable’s arrangement allows for heating a larger area of the growing medium than a point heat source would.
For more precise control of growing conditions, it is advisable to monitor the temperature in the root zone. Depending on the application, the cable can also be used with a suitable temperature control system compatible with its electrical specifications.
The cable ends and connection points feature durable seals that enhance the device’s resistance to moisture typically found in growing conditions.
However, this does not mean it can be used underwater. The cable must not be submerged or used in completely flooded areas.

The CANH3 model has a heating power of 30 W.
The heating section is 4 m long. Additionally, the unit includes 2 m of non-heating cable.
Yes. The cable can be used to provide additional heat for propagators, seedling trays, and areas designated for germination and rooting of cuttings.
The CANH3 has a power rating of 30 W and a 4-meter heating section, making it a more compact option. The CANH4 model has a power rating of 60 W and a 10-meter heating section, allowing it to cover a larger area.
Yes. It can be used for localized heating of the root zone in a grow box, provided that proper installation and electrical safety guidelines are followed.
The design features seals that enhance moisture resistance; however, the cable should not be submerged in water or used in fully submerged conditions.
That is not its primary use. The 30 W power rating is primarily intended for localized heating of the root zone, a propagator, or seedlings.
