The journey of synthetic nutrient cultivation can be both thrilling and daunting. Many believe it is not ok to use such fertigation methodologies due to commercial agriculture. There is a lot of misperception and confusion. But regardless of this. I am not here to debate Synthetic or Organic fertigation but rather to share my perspective on synthetic nutrients with those looking to get started with them. We’ll delve into some of the nuances of using salt-based nutrients, explore essential equipment, highlight the significance of each element, and address common pitfalls for those venturing into this realm.
Perhaps this week’s topic is very different to our usual things. But at times I just have to get some things off my chest. So I hope you understand…
Understanding Synthetic Nutrients
Before we dive into the equipment and procedures, let’s clarify what we mean by synthetic nutrients. In this context, we refer to salt-based nutrients, typically found in concentrated liquid or powdered forms. Unlike organic alternatives like molasses or bone meals, synthetic nutrients are precisely measured and come in bottles or packaged powders. In South Africa, the government has placed inorganic fertilizer under Group 1 which contains more than 100 g/kg of nitrogen (N), phosphorus (P) or potassium (K) as the main ingredients.
Essential Equipment
There are so many different essentials that will make growing with synthetics so much better. Unlike with traditional organic fertilizers, having accurate measurements changes everything. Hence why we list the following as the top 2 essentials for your synthetic nutrient regimen.
The quality of your equipment matters. Consider your overall budget and the importance of the tool when making the purchasing decision and do as much research on the products as possible. There is a reason some pH meters cost 20 thousand rands and others only a few hundred rands. Be mindful of this. Please also remember that the way you handle the tools will greatly add to or take away from their precision and longevity.
1. pH Testing
Maintaining the right pH level is crucial for nutrient absorption by plants. Synthetic nutrients often require specific pH ranges for optimal efficacy. Investing in a reliable pH testing kit is imperative to monitor and adjust the pH levels accurately. If you remember one of our first blogs on the topic of pH. It can be crucial to a specific growing methodology. Because synthetic nutrients are used mainly in hydroponic grows, we recommend that pH be closely monitored. Read more about it here: “pH doesn’t Matter.”
2. Parts Per Million (PPM) / Electrical Conductivity (EC) / Total Dissolved Solids (TDS) Meters
Most of the time an EC meter will also convert the measurement to TDS or into PPM. Understanding the concentration of nutrients in your solution is vital. PPM measures the parts per million of dissolved substances in the water, providing insights into nutrient strength. This tool aids in preventing over-fertilization or nutrient deficiencies. EC meters measure the electrical conductivity of your nutrient solution. This metric helps gauge the overall nutrient concentration, giving you a deeper understanding of your plant’s nutritional intake. Similar to PPM meters, TDS meters quantify the concentration of dissolved substances in your solution. Monitoring TDS is crucial for adjusting nutrient levels accurately. Check out these tools here.
The Importance of Growing Informed
In an organic setting. Not knowing everything is part of the beauty of it all. You rely on nature to do Its thing and you do your best to nurture the process. With synthetic nutrient inputs, it is always the input of the grower that will cause issues. Therefore knowing what is going on is one of the greatest assets in this fertigation methodology.
pH Testing and Nutrient Absorption
Plants absorb nutrients optimally within specific pH ranges. Regular pH testing ensures that your plants receive the nutrients in the most accessible form, preventing nutrient lockout or deficiencies. This enables a smooth grow from start to finish. When you get good at controlling and dialling in on pH. You will find that you can have plants uptake very specific nutrients at any time you prefer in the grow-cycle. Giving elite cannabis growers so much control usually turns growth into next-level operations.
Parts Per Million and Nutrient Precision
Synthetic nutrients provide specific nutrient concentrations per package, often measured in grams per kilo. Converting these measurements to parts per million allows growers to accurately dose their plants, preventing wastage and promoting efficient nutrient uptake.
Considerations for Grow Mediums
When selecting a growing medium for synthetic nutrient cultivation, it’s essential to consider the medium’s existing nutrient content. Some organic mediums may contain nutrients sufficient for the initial growth stages, requiring minimal additional supplementation. Others are completely inert. Which is what most growers using synthetic nutrients prefer. And like I mentioned earlier it is often used in Hydroponic setups.
Testing in Different Grow Mediums
Testing equipment becomes especially crucial when using inert mediums like coco coir, which lack inherent nutrients. Growers need to calculate and tailor nutrient solutions based on the specific requirements of their chosen medium. Whether the water is hard or soft and or if it is filtered in a R/O system before fertigation is all things that must be considered and at least tested for. It will create fewer headaches as you progress in the grow.
Liquid vs. Powdered Nutrients
Is there a massive difference and does it matter which you use? I don’t believe so. Although, I am biased towards the one. Liquid nutrients are convenient, ready-to-use solutions that require minimal preparation. However, spillage and the need for regular shaking to distribute particles evenly can be drawbacks. Powdered nutrients offer precise measurements, reducing the risk of wastage. With proper weighing and dissolution techniques, growers can achieve accurate nutrient concentrations without the need for frequent shaking. However, storage needs to be done in a dry place. Any moisture that finds itself inside the powdered nutrients will cause issues with the concentration of the fertigation. Often liquid fertilizer will have many different parts. This can confuse newer growers and even some seasoned ones too. The best 3 part nutrient available on the market is most likely Mega Nutrients by Hydrobiz. Powdered Synthetic nutrients normally have only 2 – 3 parts. The most popular being Greenhouse Powder Feed or Hydroponic.co.za’s Horti-mix.
Final Thoughts and Tips
Fertigation is crucial in growing a crop that will rival in today’s markets or even have just more than above-average flowers. Selecting the proper nutrients can be difficult especially because of the amount of different products out there. I advise powdered nutrients. Something that comes in either 2 parts or 3. It is better to keep it simple in the beginning.
Research is Key
Knowledge is your most potent tool. Research the specific requirements of your chosen synthetic nutrients, understand the ideal pH ranges, and familiarize yourself with the equipment needed for accurate monitoring. Set time aside to learn everything required. No setup will be the same. However, trying to create an understanding of your environment and surroundings will drastically improve your ability to produce a more successful crop.
Invest in Quality Equipment – If you can.
Having the best of the best equipment is not everything. Knowing how your tools work and ensuring you have quality tools and equipment that will last will make a difference. If your budget doesn’t allow for this. It is better to have something as a form of indication than to be blind. So spend your money wisely. Upgrade your equipment as the demand for better accuracy increases with your skillset. There is nothing wrong with an R600 pH meter if it is calibrated correctly and handled with care. Just understand the quality of the equipment you are working with. Your understanding of how pH works and your skills will bring about the need for more sophisticated equipment.
Just because you have a Hanna Instrument pH meter doesn’t mean your understanding and interpretation of the reading are correct. Take this into consideration.
Tailor Nutrient Solutions
Customize nutrient solutions based on your plant’s growth stage, medium, and environmental conditions. Regular monitoring and adjustments will contribute to healthier and more robust plant development. This takes time and a deep understanding of the nutrients you are using and the type of cannabis cultivar you are growing. My best suggestion would be to first grow some crops to completion before starting to twig too many things. It is better to take your time in understanding things than chopping and changing fertigation solutions.
Join a Community
Connect with fellow growers in forums or groups to share experiences and gain valuable insights. Learning from others’ successes and challenges can enhance your understanding and skills. The cannabis community can be tricky. Not all growers are willing to share their secrets but this doesn’t mean they are not willing to have a meaningful conversation around issues in the grow space or with plants and cultivars. A good community to look for is not too big and not too small. You do not want too many opinions to cloud your judgment on what is going on. As there are so many ways to skin the cat, it can leave a newbie very confused. Find a group with a few voices of authority. If finding a group is too difficult. Pop in by your local grow shop or nursery. An honest approach with some decent images and videos of your plant issues always will lead to answers.
Thankfully, most are willing to help.
In conclusion, synthetic nutrient cultivation offers precision and control over plant nutrition. By arming yourself with knowledge and the right tools, you can unlock the full potential of your plants, resulting in a successful and fulfilling growing experience. And perhaps synthetic nutrients are not your thing. That is fine too. Just understand that there are different strokes for different folks. When used correctly and responsibly, inorganic fertilizers are just as sustainable as organic. And in some cases even more sustainable.
