Small Measurements: User Guide

Aptus nutrients are highly concentrated. Because of that, we’re saving the environment some plastics, we’re saving you some back problems, and you’re sure you’re not paying for expensive tap water. However, when you only need a few liters of water, it can become challenging to accurately measure the nutrients you’re feeding your plants. In this […]

One of the most common questions new Aptus users have is: What EC value should I keep in my nutrient solution? Unfortunately, there’s no easy answer here, as it’s dependent on a lot of variables like crop, climate, and growth phase, but we’ll attempt to clear some of the fog surrounding EC in this article!

Enzymes 101

Enzymes are agents of change – Catalysts for biochemical reactions. In the human body, enzymes are involved in the digestion (breakdown) of food into molecules that are small enough for your body to absorb.  Without enzymes, the human body wouldn’t be able to take up the proper amount of nutrients. So, if your body would […]

The Health Factor – pH

We all know pH is an important measurement for any fertilizer input. Most of us also know that the pH of the medium is a big factor in the availability and absorption of nutrients. What only few understand is the importance of the pH of the plant itself, so that’s what this article is all […]

The Quality Factor – Brix

In our last article, we determined that plants actually request attacks from pests and pathogens. Having established that, the next question becomes: How do we get plants to send the ‘good’ signals and not the ‘bad’ in a controlled environment? That’s where Brix comes in!

Plant Signals

It’s every grower’s worst (but all-too-common) nightmare: Checking on your crop and finding out it’s infested with pests (or pathogens). Spraying pesticides only works curatively, so a preventive approach would be better. To be able to effectively prevent problems before they arise calls for a deeper understanding of plant health and signals, and that’s […]

Nutrient Interactions & Antagonism

It is very important to understand how certain nutrients react with each other. If you don’t understand these interactions, you may over-supplement with a specific nutrient in an attempt to correct a deficiency. Not all deficiencies are caused by a lack of nutrients! For example, calcium deficiency may be diagnosed due to low calcium levels […]

But, at the end of the day it’s always better to prevent problems from arising by understanding the underlying cause. When you provide the right nutrients to your plant from the beginning, in the right sequence and […]
