If you have a large or mid-size grow, you know how much work goes into tending to your plants. Automated watering systems and temperature monitoring help to reduce some of the stress, but what other automated systems have you looked into? Fertigation isn’t a new concept, but in the world of commercial cannabis growing, not many producers have fully investigated this option.
What Is Fertigation?
Fertigation is a process by which plants are given fertilizer by way of an automated delivery mechanism. In the cannabis industry, fertigation is used most often (and most successfully) with hydroponic systems, which help to evenly distribute nutrients to the plants.
The point of adding a fertigation system to your grow operation is two-fold. First, fertigation reduces the amount of hands-on time your team will need to spend measuring, mixing, and distributing fertilizer. Second, fertigation systems provide the most accurate delivery of fertilizer, reducing potential human error.
How Does Fertigation Work
The two methods of fertigation most commonly used in the cannabis industry are called ‘dilute tank control’ and ‘in-line injection.’ In both methods, the fertilizer is added to your water supply where it becomes diluted, then runs through an irrigation system to feed seeds, seedlings, and plants on a set schedule. While some fertigation systems only control the nutrient dosing equipment, others can also schedule irrigation along with nutrient dosing.
Advantages of Fertigation
Other than less hands-on work for your team, what advantages does fertigation offer?
- Direct delivery of nutrients to root zone
- Consistent and uniform distribution of nutrients
- Consistent delivery to plants without low or high periods
- Improved nutrient absorption
- Improved accuracy
Fertigation is there to save time and improve yields, but these systems still require some level of maintenance. but still requires monitoring and maintenance to perform at optimal levels. Checking for leaks, performing routine clearing of the lines, and regularly cleaning the tanks can all help to keep your fertigation system running smoothly for years.
