About us. Our 9 year history

GoToGarden started in 2017 out of personal frustration. Our founder was a hobby grower who spent hours navigating online shops that felt built by people who had never touched a plant — cluttered layouts, vague product descriptions, no real guidance on what to actually buy or why. He knew there had to be a better way.

Why Monitor Your Grow Environment with Trolmaster Sensors?

Growers face challenges such as incorrect nutrient delivery, unstable pH levels, and suboptimal CO2 concentrations, all of which can lead to reduced yields or crop failure. Trolmaster sensors provide the precise data needed to manage these critical factors, ensuring optimal conditions from seedling to harvest. For instance, maintaining EC within a ±1.0 mS/cm tolerance and pH within ±0.1 pH units is crucial for nutrient uptake, and these sensors deliver that accuracy.

Trolmaster Sensor Range for Precision Cultivation

Trolmaster offers a comprehensive suite of sensors designed to integrate seamlessly with their control systems. For basic monitoring, the Trolmaster 2-in-1 EC-Temp Sensor do nádrže (PCT-1) and Trolmaster pH Sensor do nádrže (PPH-1) provide essential reservoir data. For advanced control, consider the Trolmaster Sensor Board pro Aqua-X (AMP-2) or Trolmaster Sensor Board pro Aqua-X PRO (AMP-3), which can bridge multiple sensor inputs. Irrigation management is enhanced with inline digital flow meters like the Trolmaster 1″ Digital Flow Meter (DFM-1), Trolmaster 1.25″ Digital Flow Meter (DFM-2), and Trolmaster 1.5″ Digital Flow Meter (DFM-3). Environmental monitoring extends to CO2 with the Trolmaster Hydro-X CO2 Sensor & cable set (MBS-S8) and Trolmaster Carbon-X CO2 sensor & Cable set (MBS-K30). Soil and media monitoring are covered by sensors like the Trolmaster Water Content Sensor & Cable Set (WCS-1) and the Trolmaster Soil Moisture-Temp-EC 3-in-1 Sensor & Cable set (WCS-2). For integrated environmental sensing, the Trolmaster Hydro-X a Hydro-X PlusTemp-Humidity-CO2-Light 4-in-1 Sensor (MBS-PRO) and its replacement Trolmaster Hydro-X Replacement & Backup Temp-Humidity-Light Sensor (MBS-TH) are key. Specialized sensors include the Trolmaster Full Spectrum Quantum Sensor (MBS-PAR) for light measurement and the Trolmaster Water Detector-Monitor (WD-1) for leak detection. Heavy-duty options like the Trolmaster Heavy Duty Nutrient EC+Temp Sensor, drop-in/in-line compatible (PCT-3) and Trolmaster Heavy Duty Nutrient pH Sensor, drop-in/in-line compatible (PPH-3), alongside the Trolmaster Inline EC-Temp Sensor do nádrže, Heavy Duty (PCT-2) and Trolmaster Inline pH Sensor do nádrže, Heavy Duty (PPH-2), cater to demanding applications. These all connect to Trolmaster’s broader control ecosystem, including Trolmaster Main Controllers, Trolmaster Irrigation Control, and Trolmaster Temperatur Control systems.

Trolmaster Sensor Accuracy and Application

Trolmaster sensors are engineered for precision, distinguishing them from generic alternatives by offering calibrated, specific measurements essential for professional cultivation. Unlike some brands that offer broad ranges, Trolmaster provides dedicated sensors for parameters like PAR (photosynthetically active radiation) and NDIR CO2 measurement (0-30,000 ppm), ensuring growers have actionable data. This focus allows for fine-tuning environmental conditions, vital for maximizing yield and quality.

Choosing Your Trolmaster Sensor Setup

Growers using hydroponic systems in coco or rockwool during the vegetative stage will often start with a reservoir monitoring setup featuring EC and pH sensors like the PCT-1 and PPH-1. For more integrated control, especially in advanced hydroponic or aeroponic systems, the AMP-2 or AMP-3 sensor boards are recommended to manage multiple parameters. If precise irrigation volume is critical, flow meters such as the DFM-1 are essential. For environmental control in enclosed grow spaces, the MBS-PRO 4-in-1 sensor provides comprehensive data on temperature, humidity, CO2, and light, directly feeding into systems like the Trolmaster Main Controllers.

Frequently Asked Questions

How do Trolmaster EC and pH sensors compare for reservoir monitoring?

The Trolmaster 2-in-1 EC-Temp Sensor (PCT-1) and the pH Sensor (PPH-1) are designed for direct reservoir monitoring in Aqua-X systems. The PCT-1 measures both EC and temperature, while the PPH-1 focuses on precise pH readings with a 3.6m cable. Both offer accurate data for nutrient solution management.

What is the difference between the standard and heavy-duty Trolmaster inline sensors?

Heavy-duty inline sensors, such as the Trolmaster Heavy Duty Nutrient EC+Temp Sensor (PCT-3) and Heavy Duty Nutrient pH Sensor (PPH-3), feature 3/4" PVC fitting compatibility for drop-in or in-line use. They are designed for more demanding applications compared to the standard inline sensors like the PCT-2 and PPH-2, offering robust construction for hydroponics and laboratory environments.

Which Trolmaster sensors are best for monitoring CO2 levels in a grow tent?

For grow room CO2 monitoring, the Trolmaster Hydro-X CO2 Sensor (MBS-S8) and the Carbon-X CO2 sensor (MBS-K30) are suitable. The MBS-S8 connects to Hydro-X systems, while the MBS-K30 measures CO2 from 0-30,000 ppm and requires a separate power supply (SPH-1).

Can Trolmaster sensors measure soil moisture and environmental conditions simultaneously?

Yes, the Trolmaster Soil Moisture-Temp-EC 3-in-1 Sensor (WCS-2) allows for real-time monitoring of soil moisture percentage, temperature, and EC levels. This sensor is capable of setting alarms and sending mobile notifications for critical changes in the grow media.
