Soil pH Meter

If you are growing your marijuana plants in soil then you are best off to get a pH meter that is specifically made to measure the pH level of soil found in your garden. This works by putting probes from the tester right in the growing soil and read the pH level. There should be a guide with the meter that you can follow to make things easy. The pH meter will last for many years and keep the accuracy level up.

Soil Test Kit

If you are growing your marijuana plants in growing soil then you could also choose to use soil test kits instead. Soil test kits are very easy to use and the results are still accurate. You can get different test kits for various things to check the levels of including nitrogen, phosphorus, and potassium. The results will come in a matter of seconds for the pH level of your growing soil.

You can only get a specific amount of tests from a single soil test kit before you will have to throw it out and purchase a new one. Soil pH meters will last a lot longer but are also a lot more expensive. If you are only growing a few marijuana plants then you may want to stick with soil test kits.
