Top Agro A Fertilizer – Top Crop Base Nutrient · High Calcium Powder for Growth & Bloom

Top Agro A by Top Crop is the structural foundation your cannabis needs, a water-soluble powdered fertilizer that delivers professional results without the hassle of heavy liquid bottles. This formula is designed to be the primary source of Calcium and Nitrogen in the A+B system, ensuring your plants develop robust stems capable of supporting heavy yields.

There is a lot of confusion in the growing world regarding powdered fertilizers and two-part systems (A+B). Many growers believe that powders are difficult to dissolve, that they clog drip irrigation systems, or that they are only for expert chemists. This misinformation often leads people to stick with diluted liquids, paying for water they already have at home.

The problem with believing these myths is that you end up spending more money for less product and, worse, you might be depriving your plants of the specific stability that a solid base offers. If you don't understand how Part A works with Part B, you risk nutrient lockout or precipitation, leaving your crop hungry and your reservoir full of sludge. The fear of "messing it up" keeps you in the comfort zone of lower yields.

The solution is simpler than it seems: Top Agro A is formulated to dissolve instantly and cleanly. It is not just "food"; it is the skeleton of your plant. By understanding that this product is the Calcium-rich half of the equation, you unlock the ability to manage your nutrition with surgical precision, saving money and gaining total control over the plant's structure.

Typical myths about powdered fertilizers like Top Agro A

• Myth: Powdered fertilizers don't dissolve well and clog pipes.
  Reality: Top Agro A is 100% water-soluble and designed specifically to keep irrigation lines clean.
• Myth: You can mix Part A and Part B directly in the bottle to save time.
  Reality: Never mix them concentrated. Calcium (A) and Phosphates/Sulfates (B) react and turn into plaster (gypsum) if not diluted in water first.
• Myth: This is only for hydroponics.
  Reality: While it excels in hydro, it works perfectly in soil and coco coir, providing faster assimilation than organic solids.
• Myth: Powders are less effective than liquids.
  Reality: They are actually more concentrated and stable, as they don't degrade as easily over time.

What Top Agro A really does (and what it doesn't)

Top Agro A acts as the "architect" of your cultivation. Its main function, thanks to its 14-5-20 NPK and high Calcium content (20%), is to promote rapid cell division and build strong cell walls. It ensures that the plant has the necessary infrastructure to transport water and nutrients from the roots to the highest bud. It is the fuel for the vegetative phase and the support for flowering.

However, you must understand what it does not do: it is not a complete fertilizer on its own. It does not contain the full spectrum of Phosphorus or Magnesium needed for explosive flowering; that is the job of its partner, Top Agro B. Using only Part A would result in nutritional imbalances. It is a team player, not a solo act.

Advantages and benefits when used properly

• Maximum Concentration: Because it is a powder, you are not paying for shipping water. A small tub yields hundreds of liters of nutrient solution.
• Structural Strength: The high Calcium content ensures thick stems and branches that won't snap under the weight of heavy flowers.
• Versatility: Compatible with the entire Top Crop range and adaptable to hard or soft water (though ideal for soft water due to the added Calcium).
• Total Solubility: You can use it in automatic irrigation systems without fear of dripper blockages.
• Cost-Efficiency: Professional quality at a fraction of the cost of liquid lines, increasing the profitability of your harvest.

Tips to choose well according to your expectations

If you are a grower who values convenience above all else and has just one or two small plants, a single-bottle liquid fertilizer might be easier. However, if you are looking to scale up, improve your yield/cost ratio, or have a setup with automatic irrigation, Top Agro A is the professional leap you need to take.

• If you expect simplicity, remember: Fill the tank with water first, add A, stir, and then add B. Never mix them dry.
• If you expect savings, this format is unbeatable for medium to large crops.
• If you use RO water (Reverse Osmosis), this product is essential to restore the Calcium buffer your water lacks.

Frequently Asked Questions

Do I really need Top Agro B or can I use just A?

You absolutely need Top Agro B (Grow, Bloom, or PK). Top Agro A provides the base (Nitrogen and Calcium), but Part B provides the Phosphorus, Potassium, and Magnesium necessary to complete the diet. Using only A will lead to deficiencies.

How do I prepare the mix correctly?

Always add Top Agro A to the water first and mix until dissolved. Only then should you add Top Agro B. This prevents the nutrients from locking out and precipitating.

Is it suitable for soil?

Yes, it is excellent for soil. Just make sure not to over-fertilize, as cannabis fertilizers in mineral powder form are very potent. Follow the dosage chart starting with the lower end.

Does it affect the pH of the water?

Yes, like all mineral fertilizers, it will alter the pH. You should measure and adjust the pH after mixing all the fertilizers in the water, not before.

Personal Experience of Pevgrow’s CEO (Alan)

I've heard many growers say they are "scared" of powdered fertilizers because they think they are difficult to dose. Honestly, once you try Top Agro A, you realize that the only difficult thing was carrying 5-liter jugs of liquid that were mostly water. In my tests, what surprised me most was the speed of assimilation; plants that looked a bit dull perked up in a matter of hours after irrigation.

My advice is simple: don't obsess over the gram scale if you have a large tank, but do respect the order of mixing. I use warm water to dilute Part A first, and the result is a crystal-clear solution. If you use drip irrigation, this product is a blessing because it leaves zero residue. It's the closest thing to professional agricultural efficiency I've seen in the domestic sector.
