Measuring Devices

When it comes to keeping your cannabis plants’ basic parameters under control both indoors and outdoors, you can benefit from using high quality measuring devices that are capable of producing exact, accurate results. The information provided by measuring devices is incredibly useful when it comes to adjusting parameters and having a successful grow.

In this section you can find meters of all types so that you can know exactly what’s going on in your grow; acidity, nutrients, temperature, humidity and more.

pH and EC Meters

The quality of your water is an incredibly important part of growing cannabis, as it determines whether or not they grow correctly; pH and EC meters allow you to measure the quality of your water in as far as acidity and concentration of minerals, respectively.

What is pH?

pH levels indicate the alkalinity or acidity of a substance, and in this case the pH in your water or nutrient solution is the determining factor of how much nutrients your plants can absorb; if this parameter isn’t within the required levels depending on substrate and plant phase, you may end up with nutrient deficiencies, or even ruining hydroponic grows within a matter of hours.

In order to avoid this, you should measure pH after making your nutrient mixture and before watering; if it isn’t at the right level it can be adjusted using a pH+ or pH- product.

At La Huerta Grow Shop, we have some of the best pH meters on the market, such as the affordable Milwaukee Eco pH meter, or the Hanna Waterproof pH Meter. If you want to go a step further, we also have continuous and constant meters such as the Hanna Grocheck Continuous pH Meter.

What is EC?

EC, or Electroconductivity, measures the amount of mineral salts dissolved in a solution. In this case, it calculates the amount of minerals in your cannabis plants’ water. If the water has too high an EC, your plants won’t be able to properly absorb the nutrients given to them and they may end up presenting signs of over-fertilizing or nutrient blockage.

In grows with inert substrates such as coco coir, for example, EC is an incredibly important factor. Your plants will only be receiving nutrients from the water you give them, and most of them aren’t retained in inert substrates. Measuring your EC levels is always a handy thing to do for higher quality results. If you’re using tap water with high EC levels, you can use an osmosis filter in order to clean it, and a calcium and magnesium additive to make the water easier for your plants to absorb and increase EC slightly.

Some examples of high quality EC meters are the Hanna Hi98304 meter or the Hanna Grocheck continuous EC meter for those that need constant readings such as hydroponic growers.

Thermometers and Hygrometers

Other important parameters when it comes to growing cannabis are the temperature and relative humidity. These factors are intertwined with many growing processes, and if they’re not adequately controlled you may have problems down the line. For example, low humidity during the growth period can make it hard for your plants to grow, and high humidity during the flowering period can make it easier for fungal infections such as oidium or botrytis to get at your plants.

Thermometers

The temperature is an incredibly important aspect of growing cannabis for many reasons, and a tool that every grower needs to have on hand is the thermometer. These measuring devices allow you to know if you have to adjust the temperature in your grow room or not, lowering or raising your grow lights without burning the tips of your plants, and they can also be used to check on your water temperature.

We have thermometers with sensors, ideal for figuring out the temperature in specific areas in your grow room, as well as suction thermometers for placing in your water tank without having to hold it to get a read.

Hygrometers

As we were saying above, humidity is also incredibly important in indoor grows; excessive humidity can create the ideal climate for fungi and insect infestations. You’ll need to make sure to maintain a balanced humidity level in accordance with each stage of your plants’ growth, which is easy if you have a humidity meter, also known as a hygrometer.

At La Huerta Grow Shop you can find various thermometer and hygrometer models designed for your needs, as well as more sophisticated models designed to measure various parameters at once.

With the Cornwall Digital Humidity Controller you can measure and automatically adjust the humidity in your grow room or tent by using a humidifier or dehumidifier, and with the HI9811-5 Meter you can control pH, EC and temperature.

Measuring Cups

Another somewhat repetitive chore when it comes to growing cannabis is measuring out your nutrients when it comes time to water, especially if done by hand. At La Huerta Grow Shop you can check out our measuring cups and pipettes, which make this chore much easier and allow you to measure out exact amounts of nutrients and additives.
