GP3 Starter Kit Green Planet – Complete 3-Part Nutrient System + Additives (7x500ml)

The GP3 Starter Kit is the definitive arsenal for the hydroponic grower who refuses to compromise on quality, combining a pharmaceutical-grade 3-part base nutrient system with Green Planet's most powerful additives to guarantee heavy, resinous harvests without clogging your irrigation lines. This pack isn't just food for your plants; it's a complete nutritional program designed to cover every single phase of the crop cycle, from the first roots to the final flush, ensuring you get the absolute maximum genetic potential out of your seeds.

Why is the GP3 Starter Kit essential for your grow?

Problem: Hydroponic growing can be a headache if you don't use the right nutrients. Many growers struggle with clogged drippers, salt buildup in the reservoir, and the dreaded "nutrient lockout" that turns leaves yellow and stunts growth. Plus, buying bottles separately is confusing and expensive, leaving you wondering if you're missing a key element for fattening those buds.

Agitation: There is nothing more frustrating than checking your Hydroponic and Aeroponic Systems and finding a layer of sludge at the bottom of the tank or realizing your plants are starving because the pH is swinging wildly due to cheap fertilizers. You end up wasting time flushing lines and correcting errors instead of enjoying the process, and worst of all, your final yield suffers in weight and flavor.

Solution: The GP3 Starter Kit solves all this at once. Its formula is 100% water-soluble and free of carbonates, meaning it stays perfectly stable in your reservoir and is instantly available to your plants. By including the 3-part base (Grow, Bloom, Micro) along with specific additives for roots, flowering, and resin, you have a professional roadmap in a box. It's the cleanest, most efficient way to feed your crop without the drama.

If you are just starting out: How this kit saves your harvest

If you are new to the world of hydro or coco, the 3-part system might seem intimidating, but this kit is actually your best friend. It gives you a structured feeding chart that removes the guesswork. You don't need to be a chemist; you just need to follow the recipe.

• Visual System: The bottles are color-coded and the instructions are clear, preventing mixing errors.
• Forgiving Formula: Being carbonate-free, it helps keep the pH stable, which is the number one error for beginners.
• Complete Diet: You won't have to worry about buying extra CalMag or boosters; the kit covers the main deficiencies rookies face.

If you are an expert: Why it deserves a place in your reservoir

For the veteran grower, the GP3 Starter Kit offers the versatility you crave. The 3-part system allows you to dial in specific NPK ratios depending on the strain's phenotype or the specific week of the cycle. Plus, the inclusion of premium additives like Rezin and Massive Bloom allows you to push crop quality to the limit.

• Total Control: Adjust the Grow, Micro, and Bloom ratios to treat nitrogen-hungry Sativas or phosphorus-demanding Indicas differently.
• Zero Residue: Ideal for high-performance drip systems where clogging is not an option.
• Terpene Maximization: The additives are designed to bring out the complex aromatic profiles that top-shelf Cannabis fertilizers are known for.

Advantages and benefits of the GP3 Starter Kit

• Pharmaceutical Grade Purity: Because it uses high-quality ingredients, your plants absorb nutrients faster, leading to vigorous growth and shorter veg times.
• Explosive Flowering: With Massive Bloom and Liquid Weight included, you are guaranteeing denser, heavier flowers compared to using just a base nutrient.
• Enhanced Flavor: The Rezin additive works to increase trichome production without altering the natural taste, ensuring your buds smell exactly as they should.
• Root Health: Vitathrive ensures your root zone is robust and capable of drinking up all that nutrition.
• Cost-Effective: Buying the kit is significantly cheaper than purchasing these 7 bottles individually.

Typical mistakes this product helps you avoid

Even with the best gear, things can go wrong. This kit is designed to minimize common pitfalls, but you should still be mindful of how you use it.

• Precipitation: The high solubility prevents nutrients from falling out of solution, a common issue that starves plants of specific minerals.
• Iron Deficiency: GP3 Micro contains high-quality chelated iron, preventing the yellowing between veins often seen in fast-growing strains.
• Salt Buildup: The low salt index means you have to flush less often, reducing the risk of root zone toxicity.

Frequently Asked Questions

Can I use this kit in soil?

Yes, absolutely. While it shines in hydroponics due to its solubility, it works fantastic in soil and coco coir. Just remember that in soil, you might need to water with plain water every few feedings to prevent accumulation.

What is the correct mixing order?

This is crucial for any 3-part nutrient. Always add GP3 Micro to your water first, mix it well, and then add Grow and Bloom. Never mix the concentrates directly together in a shot glass; they will lock out.

Do I need a separate PK booster?

The kit includes Massive Bloom, which is a powerful Fertilizer for flowering additive. For most growers, this is more than enough to get rock-hard buds.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested dozens of nutrient lines over the years, and Green Planet always stands out for one thing: cleanliness. When I recommend the GP3 Kit to friends starting their first DWC (Deep Water Culture) bucket, it's because I know they won't call me a week later complaining about slime or pH swings. For my own use, I love the flexibility. Being able to drop the nitrogen right out of the mix in late flower while keeping the micros high is a game-changer for finishing strains properly. The Rezin additive is the cherry on top; the sticky factor is noticeably higher.
