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 Calibration Solutions Are Crucial for Accurate Readings

Inaccurate pH and EC readings can lead to significant issues in plant cultivation, including nutrient lockout or deficiencies, ultimately impacting yield and plant health. This collection provides the essential calibration and cleaning solutions required to maintain the precision of your pH and EC meters. By regularly calibrating your instruments, you ensure that the nutrient solutions you provide are at the optimal level, directly contributing to vigorous plant growth, especially when working with sensitive species or during critical growth stages like flowering. The need for precise measurements is paramount for consistent and predictable results.

Explore Your Calibration Solution Options

This collection offers a comprehensive range of calibration solutions designed to meet the needs of all growers, from hobbyists to professionals. For pH calibration, find solutions like Milwaukee pH 7.01 pufr 20 ml, Milwaukee pH 4.01 pufr 20 ml, and larger volumes such as Essentials LAB pH 7 pufr 1 l and Essentials LAB pH 4 pufr 1 l. EC calibration is covered by products like Milwaukee EC 1.288 20 ml, Milwaukee EC 1.413 20 ml, and bulk options such as Aqua Master Tools EC 1413 100 ml, and Aqua Master Tools EC 12.88 100 ml. Cleaning and maintenance are supported by Milwaukee Cleaning Solution 20 ml and Aqua Master Tools Cleaner D 100 ml, while storage solutions like Milwaukee Storage Solution 230 ml and Aqua Master Tools KCl 3 mol-l 100 ml extend electrode life. For comprehensive meter care, consider kits like the Milwaukee FRESH-START Kit pro pH metry a testery or Milwaukee PH START Kit pro pH metry a testery. For automated systems, explore the Automatická úprava pH collection, and for broader monitoring needs, the Monitoring collection is available. If specific components are needed, the Náhradní díly collection addresses those requirements, and for manual testing, refer to the Ruční category.

Brand Focus: Milwaukee vs. Aqua Master Tools vs. Essentials LAB

Milwaukee provides a wide array of calibration solutions, including convenient sachets for frequent use and larger bottles for professional settings, focusing on ease of use and accuracy. Aqua Master Tools offers a robust selection with a strong emphasis on bulk packaging for laboratories and large-scale cultivation operations, providing cost-effectiveness. Essentials LAB offers essential buffer solutions in larger volumes, prioritizing consistent accuracy and value for dedicated growers requiring substantial quantities for regular calibration.

Choosing the Right Solution for Your Setup

Growers using hydroponic systems with coco coir or rockwool in the vegetative stage will primarily need precise pH calibration solutions like Milwaukee pH 4.01 pufr 20 ml and EC solutions such as Milwaukee EC 1.288 20 ml. For flowering stages in soil or coco, maintaining a stable pH around 5.5-6.5 is critical, requiring regular calibration with solutions like Milwaukee pH 7.01 pufr 20 ml. If using automated dosing systems, ensure your calibration solutions are compatible with the specific meter models to prevent calibration drift. For professional cultivators, bulk purchasing of solutions like Aqua Master Tools EC 1413 100 ml or Aqua Master Tools pH 4.01 pufr 100 ml provides the most economical option.

Frequently Asked Questions

What is the purpose of calibration solutions for pH and EC meters?

Calibration solutions, also known as buffers, are used to accurately set the baseline for your pH and EC meters. This ensures that the readings you get during cultivation are precise and reflect the true state of your nutrient solution, preventing issues like nutrient lockout or deficiencies.

How often should I calibrate my pH and EC meters?

It is generally recommended to calibrate your pH and EC meters at least once a week, or before each critical measurement session. For highly sensitive applications or when using automated systems, daily calibration might be necessary to maintain accuracy.

What is the difference between calibration and cleaning solutions?

Calibration solutions (buffers) are used to set the meter's reading to a known standard value (e.g., pH 7.01). Cleaning solutions, typically containing HCl, are used to remove mineral buildup and organic residues from the meter's probe, ensuring that the probe can accurately interact with the solution being measured and is ready for calibration.

Can I use the same solution for calibrating pH and EC meters?

No, pH meters require pH buffer solutions (like pH 4.01, 7.01, or 10.01), while EC meters require calibration solutions with specific conductivity values (e.g., 1288 µS/cm or 1413 µS/cm). Using the wrong type of solution will result in incorrect calibration and inaccurate readings.
