Are you someone who fanciers all the latest tech and gadgets? Well, now, there are tons of new digital tools on the market to geek out over! Tech-savvy cannabis cultivators can use the power of cannabis wireless sensors to upgrade their grow tent with a digital personal assistant! Cannabis wireless sensors are interconnected devices that simultaneously measure climate conditions inside a grow tent. Using individual meters, such as thermometers (measures temperature) and hygrometers (measures humidity), can quickly clutter small grow spaces. Digital cannabis wireless sensors combine multiple meters into one easy-to-use system. Wireless capabilities enable growers to monitor their plant conditions directly from their smartphones!

Here are essential sensors for your grow room to take your cultivation to the next level:

• Temperature
• Relative Humidity (RH)
• Vapor Pressure Deficit V(PD)
• Electrical Conductivity (EC)
• Photosynthetically Active Radiation (PAR)

Here’s what you need to know about each sensor and how it affects your cannabis plant growth.

Measuring temperature inside your grow tent

Measuring the temperature inside your grow tent is the best way to maintain the ideal climate for growing your cannabis seeds. Thermometers are essential for any grow tent set-up. Many cannabis wireless sensor systems also include temperature readings.

The placement of the sensor is important for getting an accurate reading. Many growers keep it near plant height or at the doorway of the grow tent for a quick peek. Placing the wireless sensor too high can cause it to register more heat due to its proximity to the grow lights. Alternatively, the floor is typically the coolest area inside your grow tent.

Measuring humidity inside a grow tent

The Relative Humidity (RH) inside your grow tent impacts how much water your cannabis plant absorbs through its roots. Too humid conditions (high RH) cause your plant to absorb more water to satisfy its thirst. Too much water leads to excessive nutrient uptake. Low humidity levels (low RH) slow how much water the plant absorbs. Too little water leads to low nutrient uptake, which halts growth.

RH percentages inside a grow tent are measured with a hygrometer. Newer cannabis wireless sensor models also feature RH sensors within them.

• Seedling stage: 70% RH
• Vegetative/ growth stage: 60% RH
• Early flowering: 50% RH
• Late flowering: 40 to 45% RH

Measuring the overall climate inside your grow tent

Finally…a reason to put those secondary school math lessons to the test! Vapor Pressure Deficit (VPD) is a sensor that reads the overall climate condition inside your grow room. It’s determined by a ratio of the Relative Humidity over the overall temperature (RH/Temperature).

Here’s the best range of VPD levels you should maintain in your grow room:

• Vegetative stage: 0.8-1.1kPa
• Flowering stage: 1-1.5kPa

VPD is important to your cannabis plant because it provides insight into how well your plant is growing. A low VPD reading signals your plant can’t release enough water, which causes blockages from absorbing the minerals it needs to grow. Too high VPD signals the leaves are excessively evaporating, which slows photosynthesis.

Measuring the nutrient concentration in your soil

Soil remains the most popular medium for growing cannabis plants at home. Soil conditions significantly impact the performance of the plant roots—the lifeline of your cannabis plant! Nutrient-rich soil is an effective way to boost yields (see what’s the best soil for your cannabis plants!). Excessive or inadequate nutrient intake can harm plant growth.

Cannabis wireless monitors with root zone sensors are required to measure EC. Use these average EC levels at the different growth stages:

• Seedling stage: 0.8-1.2 mS/cm
• Vegetative stage: 1.3-1.7 mS/cm
• Flowering stage: 1.5-2.0 mS/cm

Our BioTabs Bio PK 5-8 liquid fertilizer enhances nutrients and boosts growth with is an excellent solution for enhancing the nutrients in the soil for improved yields.

Measuring cannabis plant nutrient uptake

Soil pH measures the acidity of the soil. Acidity impacts the plant’s overall nutrient uptake. Nitrogen, Phosphorus, and Potassium are the three key nutrients every cannabis plant must have to grow. Each nutrient gets absorbed at different pH levels. If the pH level is not optimised, the cannabis plant can’t absorb the necessary nutrients. Managing the pH level helps growers achieve bushier plants with massive yields.

The best pH value for cannabis plants ranges between 6.0 and 6.8. The range represents moderate acidity, which is ideal for nutrient intake. Digital pH meters have replaced pH drops for tech-savvy growers.

Measuring light intensity in your grow room

Cannabis plants love sunlight. The perfect grow lights help recreate natural sunlight in indoor grow rooms. Monitor the light intensity in your grow room using a Photosynthetically Active Radiation (PAR) meter. Digital PAR meters sync with a sensor placed inside your grow tent, eliminating the need for manual test adjustments to the light settings at the start of each grow stage.

Light intensity indicates the amount of photosynthetic energy the cannabis plant receives. Low levels indicate that the plant isn’t receiving enough energy to grow efficiently. Higher levels lead to light stress, which slows growth. Here are ideal light intensity ranges are achieved stage:

• Seedling stage: 100-300 PPFD
• Vegetative stage: 250-600 PPFD
• Flowering stage: 500-1050 PPFD
