You’ll want to ensure you have a soil PH tester to ensure your plants are growing optimally.

Contact us today and let us help you find a soil PH meter that is best suited for your budget and growing needs. We have the best soil PH tester options available both online and in-store.

Should I Purchase a Conductivity Pen?

A conductivity pen is a great tool to have when looking to grow plants to their potential. This tool allows you to identify what your plant may be lacking in terms of nutrients, allowing you to fill in the gaps. A soil meter or conductivity pen is something all growers may want to consider.

Beyond helping you choose the best ph pen, we can also support you in choosing the right hydroponic nutrients and supplements to support your plants. Let us work with you to determine the cause of your growing concerns, from there, we can offer suggestions to optimize your plants' growth.

Is a Grow Kit the Best Way to Get Started with Growing?
