The Plagron Easy Pack 100% Natural is an organic feeding kit that takes four plants from seedling to harvest without the guesswork. You get Alga Grow, Alga Bloom, and the legendary Green Sensation 4-in-1 bloom booster — all in one box, all 100% organic, all dosed to a Plagron-supplied schedule.
Why the Easy Pack 100% Natural is worth it
If you've ever stood in front of a fertiliser shelf wondering whether you need a base nutrient, a bloom stimulator, a PK booster, an enzyme, and a root tonic — this is the kit that answers "yes, but they've already boxed it for you." Plagron put together the Easy Pack 100% Natural specifically so a first-time grower (or a returning hobbyist who can't be bothered to spreadsheet a feeding chart) can run four plants on a complete organic line without buying six different bottles.
The Alga line is seaweed-based — Norwegian kelp extract is what gives it the deep mineral profile and the gentle release. Organic nutrients are more forgiving than mineral salts: harder to burn your roots, better for the soil microbiome, and the end product tastes cleaner. The trade-off is that organics work with the soil rather than over it, so you do need a living substrate (a decent peat or coco-light mix) for the bacteria to do their job. On inert media or pure coco, you'd be better off with the Terra or Coco line.
And then there's Green Sensation. This is Plagron's flagship 4-in-1 — flowering stimulator, bulking agent, hardener, and flushing agent rolled into one bottle at NPK 0-8-9. Used in the last 4–5 weeks of flower at 1ml/L, it's the bottle most growers will tell you actually moved the needle on yield and resin density. 50ml goes a long way at that dose.
What's in the box
| Bottle | Volume | NPK | Used during |
|---|---|---|---|
| Alga Grow | 250ml | 4-2-4 | Vegetative phase |
| Alga Bloom | 250ml | 3-2-5 | Flowering phase |
| Green Sensation | 50ml | 0-8-9 | Last 4-5 weeks of flower |
Easy Pack Natural vs Easy Pack Terra — which one for you?
Plagron makes three Easy Packs and the difference matters. Pick the one that matches your substrate.
| Pack | Substrate | Style | Pick if... |
|---|---|---|---|
| Easy Pack 100% Natural | Organic soil / light mix | 100% organic, seaweed-based | You want clean taste and a forgiving feed |
| Easy Pack Terra | Pre-fertilised soil | Mineral, faster response | You want bigger, faster yields on soil |
| Easy Pack Coco | Coco coir | Mineral, coco-specific | You're growing in coco |
Dosage — straight from Plagron's schedule
The Easy Pack ships with a printed grow schedule on the box. The short version below covers the standard dilution rates Plagron publishes for the Natural line. Always shake the bottle before use and feed to runoff with pH-adjusted water (around 6.0–6.3 for soil).
| Phase | Product | Dose per litre water |
|---|---|---|
| Veg (week 1–3) | Alga Grow | 2–5 ml/L |
| Early flower | Alga Bloom | 2–5 ml/L |
| Mid–late flower (last 4–5 weeks) | Alga Bloom + Green Sensation | 4 ml/L + 1 ml/L |
| Final week (flush) | Green Sensation only | 1 ml/L in plain water |
Pairs well with a basic pH meter and pH-down — even on organics, water that's way out of range stops nutrients getting absorbed. If you're growing in pre-fertilised soil rather than a light mix, look at the Plagron Easy Pack Terra instead.
How to use the Easy Pack 100% Natural
- Shake each bottle well before measuring — organic nutrients settle.
- Fill your watering can with tap water and let it sit 24h to off-gas chlorine, or use RO/filtered water.
- Add Alga Grow during weeks 1–3 of vegetative growth at 2–5 ml/L.
- Switch to Alga Bloom when you flip to 12/12 (or when outdoor plants start showing pre-flowers).
- Start Green Sensation at 1 ml/L from roughly week 4 of flower onward, alongside Alga Bloom.
- Final week: drop the Alga Bloom, run Green Sensation only at 1 ml/L for a clean finish.
- Check pH after mixing — aim for 6.0–6.3 in soil.
- Store the bottles in a cool, dark place. Organic formulas don't love sunlight or heat.
Honest limitations
This is a starter-friendly kit, not a competition setup. Two things to know going in: the 250ml bottles will comfortably feed four plants of average size through one cycle — if you're running a packed 1m² tent with vigorous strains, you'll likely run out of Alga Bloom before the end of flower and need to top up. Second, organics need a living substrate. If you've got plants in pure coco or rockwool, the Alga line won't break down properly and you should run the Terra or Coco pack instead.
Frequently Asked Questions
How many plants does the Easy Pack 100% Natural actually feed?
Plagron rates it for around four average-sized plants from seedling to harvest. Bigger plants or longer-flowering strains may need a top-up bottle of Alga Bloom toward the end.
Is this suitable for coco coir?
No — the 100% Natural line is built for organic soil. For coco, get the Plagron Easy Pack Coco. For pre-fertilised soil, the Easy Pack Terra is the better match.
What does Green Sensation actually do?
It's a 4-in-1 additive used in the last 4–5 weeks of flower: flowering stimulator, bulking agent, hardener, and flushing agent in one bottle at NPK 0-8-9. Most growers see denser buds and better resin production at 1 ml/L.
Do I still need to flush at the end?
Green Sensation doubles as a flushing agent in the final week — run it at 1 ml/L in plain water without the Alga Bloom. That's Plagron's recommended finish.
Can I use this outdoors?
Yes. The Alga line works just as well in outdoor soil as in indoor pots — the seaweed base is gentle on the soil microbiome and forgiving if you miss a feed.
Why organic instead of mineral nutrients?
Organic feeds are harder to overdose, easier on the soil life, and tend to give a cleaner end-product taste. Mineral nutrients respond faster and often push bigger yields, but they're less forgiving if you miscalculate.
