Dutch Pro Explode — All-In-One Bloom Booster for Maximum Flowering Performance
Best for: Experienced growers wanting a single bloom stimulator that replaces the need for separate PK boosters and additives
Our thoughts
This is proper kit from growers who've been doing it seriously for 30 years. Explode does what a bloom booster should do — simplified feeding, no need to juggle multiple bottles, and it actually works. Not a beginner's product, but if you know what you're doing, it's worth the investment.
Dutch Pro Explode is a complete bloom stimulator designed to accelerate flowering production and deliver the concentrated nutrients plants need during the critical bloom stage. Unlike traditional PK boosters that require separate application schedules, Explode is an all-in-one flowering enhancer formulated with phosphorus, potassium, micronutrients, vitamins, and fulvic acid — everything you need in one bottle. It's the choice of professional growers across Europe, and it eliminates the guesswork of juggling multiple additives during flowering.
How it compares
Explode sits in the all-in-one bloom booster category, distinct from traditional high-concentration PK products.
- Complete formulation with micronutrients and vitamins — not just raw phosphorus and potassium
- Simplifies your feeding schedule by replacing the need for separate PK 13/14 boosters
- Balanced NPK ratio (0-0-4) designed for progressive dosing across the flowering cycle
- Water-soluble ingredients suit all growing systems — hydro, coco, soil, drip, flood and drain
- 30-year professional pedigree; preferred by experienced growers over entry-level alternatives
In short: one bottle, proper formula, no mixing and matching with different PK concentrations.
Usage guidance
Explode is applied during the flowering stage only, with dosing that increases progressively as flowers develop:
When to start
Begin application when flower development first appears. Continue until one week before final flush.
Progressive dosing schedule
Weeks 3–4 of flowering: 0.5 ml/L
Weeks 5–6 of flowering: 1 ml/L
Week 7 of flowering: 1.5 ml/L
This progressive approach matches plant demand as flowers develop and mature.
Application method
Add your base nutrient first, then add Explode to your water tank. Mix thoroughly and adjust pH as normal. Simple as that.
System compatibility
Works with hydro, coco, soil, rockwool, and any drip or recirculating system. The water-soluble formulation means it's readily available to roots across all mediums.
Critical usage note
Do not combine Explode with any other PK booster or bloom additive. This is an all-in-one product — using it alongside separate PK supplements will almost certainly cause nutrient overfeeding and lock-out. That's the whole point: one bottle, job done.

Who this is for
- Experienced growers who've dialled in their base nutrients and want to add targeted bloom support
- Anyone running multiple plants or rooms where simplifying the additive stack saves time and cost
- Growers using hydroponic, coco, or high-frequency feeding systems where water-soluble boosters work best
- Professionals and serious hobbyists who value proven track records over budget alternatives
- Growers frustrated with juggling separate PK 13/14 boosters — this replaces that entire step
Not a beginner's product. This is for growers with solid fundamentals who understand nutrient balance and feeding schedules. If your plants are struggling or your base program is inconsistent, Explode won't fix that — get the basics right first.
Our take
Dutch Pro Explode is professional-grade flowering stimulator backed by 30 years of European grower experience. It does what a bloom booster should do: deliver concentrated nutrients exactly when flowers need them, without complicating your feeding schedule. The all-in-one formulation is the real win here — one bottle instead of three, one dosing schedule instead of five, no overfeeding risk from stacking products.
It's not cheap, and it's not for everyone. But if you're running a dialled-in setup and want reliable, proven performance at the critical flowering stage, worth picking up while stock lasts. Does exactly what it should, week in, week out.
