How to Use Dutch Pro Explode

Dutch Pro Explode is a powerful bloom stimulator designed to maximise flower production in the final weeks of the growing cycle. This guide covers dosing, timing and how to get the best results in your setup.

Using Dutch Pro Explode correctly will make a real difference to your results. Dutch Pro Explode is one of the most complete bloom boosters I’ve come across — and that’s genuinely saying something in a market flooded with single-purpose PK additives. What sets Explode apart is that it handles your PK uplift, flower hardening, aroma intensification, vitamins, and micronutrients in a single, balanced formula. Used correctly through your flowering cycle, it consistently delivers heavier, denser, more aromatic results without the overfeeding risk that comes from stacking multiple bloom additives.

What Does Dutch Pro Explode Do?

Explode is designed to be added during the flowering stage to push your plants toward their maximum potential in terms of flower density, weight, and essential oil production. Its NPK profile is 0-0-4, so the phosphorus and potassium it delivers are specifically calibrated to support heavy flower development without excess nitrogen that could interfere with late bloom.

The formula also contains vitamins, amino acids, and key micronutrients that feed directly into the processes responsible for resin production, fragrance, and overall fruit quality. It’s a genuinely complete bloom booster — which means you don’t need to add a separate PK 13/14 alongside it. In fact, Dutch Pro specifically advise against it: adding another PK supplement on top of Explode risks pushing your plant into nutrient excess.

Dutch Pro Explode Dosage — Week by Week

For a standard nine-week flowering cycle, Dutch Pro recommend the following schedule:

• Weeks 1–2 of bloom: No Explode — let your plants transition into flowering using your base nutrient schedule
• Weeks 3–4: 0.5ml per litre — introduce Explode at low dose as flowers begin to form
• Weeks 5–6: 1ml per litre — increase as flowers swell and develop
• Weeks 7–8: 1.5ml per litre — peak dose to harden tops and intensify aromatics
• Week 9: Flush only — no Explode or other nutrients in the final week

For shorter or longer flowering varieties, scale the schedule accordingly — starting low and building progressively to peak dose before dropping off for the flush period.

How to Mix Dutch Pro Explode

Getting the mixing order right matters, especially with a multi-compound formula like Explode.

• Shake the bottle thoroughly before measuring — the active compounds can settle
• Start with clean, pH-adjusted water in your tank
• Add your base nutrients first, mix well
• Add Dutch Pro Explode at the appropriate dose for your current week
• Stir the full solution, then check EC — Explode will raise your overall EC level
• Adjust pH last: target 5.8 for hydroponic systems, and 5.8–6.5 for soil and coco

Always check EC after adding Explode before feeding your plants. Because it adds potassium and other compounds to your solution, it contributes meaningfully to overall electrical conductivity — especially at peak dose in weeks 7–8.

When to Start Using Explode

Begin Explode as soon as flowers, buds, or fruits are visibly forming — typically around week 3 of the bloom period. Starting too early (before any flower sites appear) wastes product and can add unnecessary load to your nutrient solution. Starting too late means missing the early swelling phase when Explode has the greatest influence on final flower size.

Compatible Growing Systems

Dutch Pro Explode is suitable for use in any growing medium or system:

• Hydro: Works well in DWC, NFT, and recirculating systems — keep EC and pH in range at all times
• Coco coir: Apply at every watering; coco rewards consistent feeding through bloom
• Soil: Allow the medium to partially dry between waterings (not completely) to encourage healthy root zone oxygen levels

Why You Don’t Need a Separate PK Booster

This is the question I get most often about Explode. Many growers habitually use a PK 13/14 or similar additive through flowering and want to know if they can keep it alongside Explode. The answer is no — and the reason is straightforward. Explode already contains a full PK profile balanced for the flowering period. Adding more on top risks locking out calcium, magnesium, or iron at a critical stage. Trust the formula and let it do its job.

Frequently Asked Questions

Can I use Dutch Pro Explode with other nutrient brands?

Yes — Explode is designed to work alongside any base nutrient range, not just the Dutch Pro line. It functions as a standalone bloom booster regardless of what base feed you’re using. Just monitor EC carefully when combining products.

Can I use Explode in a one-part nutrient system?

Yes. Explode is an additive, not a replacement for your base feed. Continue using your one-part base as directed and add Explode on top according to the bloom schedule above. Check your total EC before feeding.

Will Dutch Pro Explode work for fruiting vegetables and herbs?

Absolutely. It’s excellent for tomatoes, peppers, strawberries, and other fruiting crops grown indoors or in polytunnels. The potassium uplift and amino acid content are particularly beneficial for fruit set and flavour development in edible crops.

What pH should I run with Dutch Pro Explode?

Dutch Pro recommend 5.8 for hydroponic systems. For soil and coco, a slightly wider range of 5.8–6.5 works well. Always adjust pH as the final step after adding all nutrients and additives to your tank.
