DrainMaster Extender
With the new DrainMaster Extenders, you can achieve flexible and precise height adjustment for your standard DrainMaster. The extenders are specifically designed to lift individual plants or bring multiple pots in a grow box to the exact same level. This creates a clean, organized, and professional setup.
How Do the Extenders Work?
Each extender module is part of a modular plug-in system. Four extenders together provide exactly 5 cm of additional height. The modules are simply plugged into each other, forming a stable unit under each foot of the DrainMaster.
You can stack as many levels as you like on top of each other, adjusting the height to your setup with millimeter precision. The key advantage: The space requirement grows exclusively upwards; the footprint remains unchanged.
Benefits at a Glance
- Modular plug-in system for precise height adjustment
- Exactly 5 cm height compensation per set of 4
- Infinitely expandable by simple stacking
- Ideal for grow boxes with plants of different sizes
- Space-saving as width and footprint remain the same

Material and Quality
The DrainMaster Extenders are made of high-quality ASA injection molding. This material is particularly UV-resistant, temperature-stable, and extremely robust. ASA is also used in professional outdoor components and is perfect for permanent use in the growing area. Even with several extenders stacked on top of each other, the system remains stable and dimensionally stable. The plug-in connections are precisely designed and ensure safe load distribution under each foot of the DrainMaster.Modularly stackable
Thanks to the modular design, you can combine multiple extender sets and gradually increase the height of your DrainMaster. The stacked modules interlock cleanly, forming a stable column without wobbling or breaking out to the side. Ideal if you want to expand your setup later or adapt it to new plant heights.Compatibility
The extenders only fit the standard DrainMaster. A separate version is planned for the DrainMaster XL.Application Examples
The DrainMaster Extenders are always used when plants are not at the same height or the light is unevenly distributed. For example, use the Extenders if:- individual plants are smaller and need to be brought closer to the light source
- multiple DrainMasters are next to each other and need to be aligned exactly
- you want a uniform plant height in the grow box for optimal light distribution
- you want to compensate for different pot sizes
Scope of delivery
4 extenders for an increase of exactly 5 cm. Additional sets can be added and combined as required. It’s almost time.
