To any cannabis growers, automating a grow room offers multiple advantages. Ventilation and lighting systems are automated using atmospheric controllers which keeps humidity, temperature, and photoperiods all in check.

Some cultivators are bumping automation to the next level by adding auto-dosing into the mix. This device regulates the pH concentration of the nutrient solution.

An auto-doser such as the Milwaukee MC720 pH Controller is a network of equipment that aids pH level maintenance in an automated soil watering scheme or a hydroponic system. This doser measures the pH within the reservoir and makes adjustments automatically. These modifications aim to bring the configurations to the pre-set levels.

Milwaukee MC720 pH Controller with Dosing Pump Kit

Milwaukee MC720 pH Controller with Dosing Pump KitThe pH controller (MC122) and dosing pump (MP810) delivers a fully automated pH control of aqueous solutions in hydroponic systems. It is specifically designed to control the pH in mixing reservoir or tanks for fertilization. It can be purchased at Growers House for $285.64 and covered by a 2-year warranty.

It features a peristaltic pump with a small and precise flow that maintains the ideal pH in the tank.

This pH controller measures the solution’s pH value and automatically adds pH adjustment (acid or alkaline) to change the liquid’s pH to the selected level.

The MC720 kit includes MC122 pH Controller and MP810 Dosing Pump.

pH controller advantages

Milwaukee MC720 pH Controller with Dosing Pump KitpH auto-dosers maintain proper pH in the hydroponic system’s water reservoir or water feed lines. Most auto-dosers work in conjunction with a controller or include one that monitors the concentration of pH in the solution and triggers the self-activating system to make necessary adjustments.

Although all automatic pH Controller has the same basic function, the components that make up the system will impact the way a grower sets up and operate in the grow space. One of the most crucial steps in choosing a pH Controller system is that it fits in the grow room’s layout.

The biggest advantages of this system to cannabis horticulturists is the enhanced efficiency and labor savings due to the increased pH consistency in the solution.

On an average, hydroponic growers spend around 20 to 40 minutes per day in monitoring pH levels in the reservoir and making adjustments as needed. Using pH controllers eliminates these steps thus saves time and labor every day. This sums up to significant savings when the entire grow cycle is considered. With time liberated and money saved, growers get time to increase efficiency in other areas around the grow room.

Consistency is one of the keys to unlocking an indoor grow space’s full potential. In fact, the biggest edge of indoor horticulture, in general, is the heightened control over the garden’s parameter. Automatic pH dosers further enhances by offering full control over the consistency of a hydroponic system’s pH concentration in turn plants tend to respond better with its nutrient uptakes.

In a typical hydroponic system, the pH level is tracked by constantly testing to ensure levels are within the desired range. Tracking and adjustments vary from once to a few times a day.

Unfortunately, pH can fluctuate out of the desired range in a relatively short period of time and may be out of the schedule. Tracking a few rounds per day can eat up a lot of time while doing it only once a day can risk an imbalance pH in the system.

On top of that, the factor for human error is on the table. It is common for growers to over or under compensate when buffering pH. This can cause stunted growth or even nutrient lockout.

Implementing an auto pH Controller system reduces the likelihood of human error and leads to a consistently balanced pH for the entire duration of the plant’s life. Auto-doser controllers, like the Milwaukee MC720, can be set to monitor and make adjustments as often as every five minutes. With a consistent pH value, the plant’s ability to uptake nutrients are never compromised all throughout its grow cycle.

Easy pH Monitoring and Adjusting

Milwaukee MC720 pH Controller with Dosing Pump KitHobbyists with large hydroponic systems or commercial growers should consider an auto pH Controller system with a peristaltic pump as a sound long-term investment. That said, Milwaukee MC720 pH Controller serves as a valuable tool for marijuana growers.

With a pH system controller system keeping the concentration of the pH of the solution continuously in the desired range, growers can simply sit back and watch the garden grow. Buy Milwaukee MC720 pH Controller with Dosing Pump Kit Click Here!
