Easy Combo Booster Pack 5 — Organic Plant Nutrition
The Easy Combo Booster Pack 5 is a set of slow-release organic fertiliser tablets from Royal Queen Seeds that covers your plants' nutritional needs from sprout to harvest. Five colour-coded tablets — two brown for vegetation, three pink for flowering — dissolve gradually to deliver a balanced feed without the faff of measuring liquids, mixing ratios, or second-guessing your EC meter. Drop them in, let them work, and get on with the rest of your grow.
We've sold plenty of nutrient lines over the years, and the most common mistake we see — especially from first-time growers — is overfeeding. Burnt tips, lockout, panicked flushes. These tablets sidestep that entire headache. Royal Queen Seeds field-tested the formulation from seedling through harvest, and the slow-release mechanism means your plants get a steady drip of what they need rather than a feast-or-famine cycle. It's not the most customisable feeding system on the market (more on that below), but for straightforward grows it's hard to beat on simplicity.
What's Inside the Easy Combo Booster Pack
Each pack contains exactly 5 compressed organic tablets. The brown tablets handle the vegetative phase — nitrogen-heavy nutrition that drives root expansion, thick stems, and dense green foliage. The pink tablets are formulated for flowering, supplying the phosphorus and potassium your plants demand when they're building flower sites and producing resin. Royal Queen Seeds colour-coded them specifically so you can't mix them up, which is a small detail that saves real trouble.

Why the Easy Combo Booster Pack Works for Simple Grows
Liquid nutrients give you control. That's their strength and their weakness. If you enjoy dialling in precise NPK ratios week by week, adjusting for runoff pH, and keeping a feeding calendar taped to your tent — liquid lines are your thing. But if you'd rather not turn your hobby into chemistry homework, these tablets exist for exactly that reason.
The slow-release format means each tablet breaks down over the course of the grow phase, releasing nutrients at a rate the plant can actually absorb. Royal Queen Seeds designed the ratio so your plants get unrestricted access to growth-boosting minerals without the twin risks of overfeeding or underfeeding. We've watched customers switch from complex 3-part liquid systems to these tablets and pull perfectly healthy harvests with a fraction of the effort. Root growth stays expansive, vegetation comes in thick and green, and flower sites develop volume without you hovering over a measuring syringe.
The honest limitation: you can't fine-tune mid-grow. If a plant shows a specific deficiency — say, a calcium issue in late flower — you can't just bump one element. You'd need to supplement with a standalone additive. For most growers running healthy genetics in decent soil, this never becomes a problem. But if you're chasing competition-level yields from finicky strains, a full liquid line gives you more levers to pull.
How to Use the Easy Combo Booster Pack 5
- Start with your brown vegetative tablets. When your plant enters the vegetative growth phase (after the seedling stage has passed and you see established true leaves), dissolve 1 brown tablet in 3–5 litres of water. Use this solution to water your plants as normal.
- Continue using the brown tablet solution throughout the vegetative phase. The slow-release formula delivers a steady supply of nitrogen and supporting minerals that promote strong stems, healthy branching, and vibrant green foliage.
- When your plant transitions to the flowering phase — either triggered by light cycle change (photoperiod strains) or naturally (autoflowers) — switch to the pink tablets. Dissolve 1 pink tablet in 3–5 litres of water.
- Use the pink tablet solution for the duration of flowering. The 3 pink tablets in the pack are designed to carry your plants through the entire bloom cycle, supporting extensive flower site development and resin production.
- Water as you normally would, allowing the slow-release nutrients to feed your plants gradually. No additional mixing, measuring, or supplementing is needed for standard grows in soil.
One tip from behind the counter: don't combine these tablets with a full liquid feed schedule. The whole point is that they replace your base nutrients. If you stack them on top of another feeding programme, you're back to the overfeeding problem these were designed to eliminate.
Easy Combo Booster Pack vs. Liquid Nutrient Lines
The question we get asked most often about these tablets is whether they're "as good as" a proper liquid nutrient system. The answer depends entirely on what kind of grower you are.
| Factor | Easy Combo Booster Pack 5 | Multi-Part Liquid Nutrients |
|---|---|---|
| Ease of Use | Drop a tablet in water — done | Measure 2–5 bottles per feed, adjust pH |
| Risk of Overfeeding | Very low — slow-release mechanism | Moderate to high without experience |
| Customisation | Minimal — fixed ratio per tablet | Full control over individual elements |
| Best For | First grows, autoflowers, simple setups | Experienced growers, competition yields |
| Cost per Grow | Low — 5 tablets cover a full cycle | Higher — multiple bottles needed |
| Organic | Yes | Varies by brand |
For a first-time grower running 1–4 plants in soil, the Easy Combo Booster Pack is the best organic tablet fertiliser you can start with. It removes the guesswork entirely. For growers running hydro setups or pushing genetics to their absolute ceiling, a liquid line with separate veg and bloom components gives you the granularity you need. Both approaches produce good cannabis — they just suit different temperaments.
Complete your setup: pair the Easy Combo Booster Pack 5 with Royal Queen Seeds genetics for a matched feeding-and-genetics combination. If you're growing in a tent, a pH meter is still worth having — even with slow-release tablets, your water source matters. And if you want to push resin production further in late flower, a standalone PK booster can complement the pink tablets without overcomplicating things.
From Our Counter: What We've Seen with These Tablets
We've been stocking Royal Queen Seeds products for years, and the Easy Combo Booster Pack is one of those items that quietly outsells flashier nutrient brands. The customers who buy it tend to be growing 1–3 plants on a windowsill or in a small tent, often autoflowers, and they want something that just works without a learning curve. The feedback we get is consistently the same: healthy plants, no drama, decent harvests.
The texture of the tablets themselves is dense and chalite — they feel like compressed soil supplements, which is essentially what they are. They dissolve fully in lukewarm water within about 10–15 minutes with occasional stirring. The brown tablets have an earthy, slightly composty smell. The pink ones are milder. Neither is unpleasant — you're working with organic material, so it smells like what it is.
The one thing we'd flag: if you're growing in a very small pot (under 3 litres), the nutrient concentration from a full tablet might be more than a small plant needs early on. In that case, use half a tablet and save the rest. Royal Queen Seeds designed these for standard 5–11 litre pots, so scale accordingly.
Frequently Asked Questions
Can I use both a brown and pink tablet at the same time?
No. The brown tablets are for the vegetative phase and the pink tablets are for flowering. Use them sequentially, not together. Mixing them would throw off the nutrient ratio your plant needs at each stage.
Do the Easy Combo Booster tablets work with autoflowering strains?
Yes. Autoflowers have a shorter vegetative phase, so you may only need 1 brown tablet before switching to the pink flowering tablets. The slow-release formula works well with the faster lifecycle of autoflowering genetics.
Can I use these tablets alongside other fertilisers?
The tablets are designed as a complete nutritional solution, so adding a full liquid feed on top risks overfeeding. If you want to supplement with a specific additive — like a PK booster in late bloom — that's fine, but don't run them alongside a full base nutrient schedule.
How many plants does one pack cover?
One Easy Combo Booster Pack 5 covers a single plant's full lifecycle — 2 tablets for veg, 3 for flower. If you're growing multiple plants, grab one pack per plant.
Do I still need to check pH when using these tablets?
The tablets don't adjust your water pH. If your tap water is very hard or very soft, it's still worth checking pH and adjusting to the 6.0–6.5 range for soil. The tablets handle nutrition, not water chemistry.
