The Best Nutritional Ingredients for Growing Cannabis

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. 

FloraMicro solution, on the other hand, is a boosting solution used to complement both FloraBloom and FloraGro. It's rich in calcium and nitrogen for higher yields and better plant growth. You can use it in all phases of development, up to the harvesting stage.

How to Use the Flora Trio

Another exciting thing about the General Hydroponics Flora Trio is that you can prepare it in advance, and then store the water nutrient for up to a week. Your water nutrient will last longer if its container is full. 

Also, remember to keep your storage jars in the dark areas with cool temperatures. That way, you can expect your nutrients to last for approximately five years, even after opening the lid. 

In addition to helping you save some cash, using small amounts of nutrients makes your nutrient-water adopt a lighter color. This makes it easy to use drop-type pH testers.

Buyers Guide on the Best Hydroponic Nutrients for Growing Weed

Now that you've gone through our top picks, you're probably wondering which hydroponic nutrient you should choose. Although each of the options above offers excellent results, you want to be sure that you're purchasing nutrients that meet your specific needs.

Some of the key features that you need to consider before you go shopping include;

Liquid or Solid

You want to decide which type of hydroponic fertilizer you'd like to use. Generally, hydroponic nutrients come in both solid and liquid states, and each type brings forth different benefits.

Although solid hydroponics are a bit less expensive, they rarely mix well. So if you'll opt for a solid fertilizer, settle for something that's highly water-soluble.

Liquid fertilizers, on the other hand, are easier to mix. However, not all liquid formulas dissolve well in water. So, ensure you choose one that's water-soluble.

Amount of Components

Hydroponic nutrients are available in either one-part or multi-part systems. One-part systems come with only one formula of nutrients, which you're supposed to mix in water and make the fertilizer solution.

With a multi-part system, you'll have three-part systems that feature several different hydroponic nutrient solutions. This option allows you to mix the various components at a ratio of your liking or use different formulas for different growth cycles.

Although a single-step system is much easier to use, you can't customize it. Alternatively, you can customize the hydroponic nutrients your marijuana plants receive, but doing so needs more work.

Grow Like a Pro

As you can see, there's no better way of growing the healthiest cannabis plants than using hydroponic nutrients. With the information presented above, you should settle for the best option that meets your specific needs and helps you grow the most robust hydroponic garden.
