Growth Booster Grotek – High-Potency Vegetative Stimulator NPK 16-40-0

Growth Booster by Grotek is the legendary "Blue Salt" you've heard the pros talk about, a high-performance vegetative biostimulator designed to turn your seedlings into green giants in record time. If you are looking to shorten the vegetative cycle without sacrificing structure, this concentrated powder delivers a massive load of nutrients (NPK 16-40-0) to ensure your plants develop a robust framework capable of supporting heavy buds later on.

Stop wasting time and electricity during the vegetative phase

We know the feeling: you check your Grow tents every day, but your plants seem stuck in slow motion. Having a shelf full of weak stimulants that promise miracles but require daily dosing can be frustrating and confusing. You end up with a complicated feeding chart, measuring out five different liquids, and yet the plants still look frail or take weeks to reach the desired height.

This delay isn't just annoying; it's expensive. Every extra week of vegetative growth means more electricity bills, more water, and a longer wait until harvest. Plus, weak plants often suffer from transplant shock, stalling their progress even further and leaving you wondering if you'll ever flip them to flower.

The solution is simplification through potency. Growth Booster acts as a single-shot injection of vitality. Instead of mixing complex cocktails every day, you apply this potent booster once at key moments (like after transplanting), and it instantly hardens the plant's structure, explodes root development, and accelerates vertical growth. It’s the ultimate tool for the efficient grower.

One product to rule the vegetative stage

This product is designed to replace the need for constant, low-dose nitrogen supplements during the early stages. By providing a high concentration of Phosphorus (40%) and Nitrogen (16%) in a single hit, it forces the plant to focus entirely on structural development.

It works perfectly in Soil For Cannabis, coco, and hydroponic systems. Note that Grotek has optimized this formula (formerly known as Vegetative Growth Booster 8-39-0) to be even more effective with a 16-40-0 ratio. It’s a "less is more" approach: you use less product, less often, for a much bigger impact.

What you simplify in your grow room with Growth Booster

Once you integrate this booster into your routine, you stop relying on hope and start relying on chemistry. Here is what changes:

• Eliminate slow starts: No more waiting weeks for cuttings to "wake up" after rooting.
• Reduce bottle clutter: You won't need multiple weak growth additives; this one jar does the heavy lifting.
• Simplify transplanting: One watering with Growth Booster immediately after moving pots drastically reduces stress.
• Shorten the cycle: You can flip to flowering sooner because the plant builds its structure faster.

How to apply it for maximum efficiency

1. Identify the moment: Use it only once when cuttings start vegetative growth or immediately after transplanting.
2. Prepare the mix: Dissolve 1g per 10 liters of water. It is highly concentrated, so do not overdose.
3. Check your base: Mix only with water (no other nutrients) for that specific irrigation to avoid burning the roots.
4. Water the substrate: Apply directly to the root zone. Never use as a foliar spray.
5. Watch them pop: Resume your normal feeding schedule with base Cannabis fertilizers in the following irrigations.

Advantages and benefits of a boosted crop

• Explosive Root System: The high phosphorus content isn't just for flowers; in early stages, it builds a massive root network.
• Sturdy Stems: Creates thick branches capable of holding heavy colas without snapping.
• Cost Effective: Since you use it so sparingly (1g/10L), a small container lasts for many crops.
• Professional Results: Corrects nutrient deficiencies in the vegetative stage before they become visible problems.

Frequently Asked Questions

Can I mix Growth Booster with other fertilizers?

It is best to use it alone with water for the specific application day. Because it has such a high NPK (16-40-0), mixing it with a strong base nutrient could cause nutrient burn (over-fertilization). Treat it as a standalone meal for your plants.

Can I spray it on the leaves?

No. Growth Booster is strictly for root application. It is a salt-based product that can severely burn the leaves if applied as a foliar spray. Always dissolve it in water and irrigate the substrate.

How often should I use it?

This is a "one-shot" product. Use it once when vegetative growth begins (e.g., when cuttings take hold) and once after transplanting to a larger pot. You do not need to use it with every watering.

Personal Experience of Pevgrow’s CEO (Alan)

I've been using what we call the "Blue Salt" since the days it was labeled Vegetative Growth Booster. Honestly, it's one of those products that stays in my kit because it just works. I use it specifically when I move my clones to their final pots. That transition can sometimes stall the plants for a few days, but with a dose of Growth Booster, they don't just recover; they sprint.

My advice: respect the dosage. It is incredibly potent. I've seen people try to double the dose thinking "more is better," and they end up with clawed leaves. Use 1g per 10 liters, and you will shave days off your vegetative cycle. It’s the most efficient way to get to the flowering stage faster without weak stems.
