The General Hydroponics Flora Trio contains the right ingredients for growing weed. These ingredients contain natural humic extracts that promote mineral release for healthy growth and development during your plant's growth cycle.

Each trio has a vital role in providing your cannabis plants with the proper nutrients at the correct growth stage. For instance, the FloraGro contains essential nutrients for strong cannabis plant roots and plant support during the germination stage.

Essential Nutrients for Plant Growth

As for cannabis nutrients, aside from Nitrogen, Phosphorus, and Potassium, two other crucial nutrients needed for growth are calcium and magnesium. Calcium and magnesium are not only vital soil nutrients, but they're also critical hydroponic nutrients

Now let's take a look at the role of each compound. Calcium is super crucial for cell division and formation in cannabis plants. If it lacks, the overall growth of your plant and its parts will be stunted.

It's also essential in activating certain enzymes in plants. These minerals have a key role in crucial activities, such as translocation and nitrogen metabolism. Like calcium, magnesium plays a pivotal role in enzyme production.
