Plagron Nutrients - Start Up — All-In-One Growth Nutrition with Root Stimulator
Best for: New growers wanting simple, organic early-stage nutrition that handles seedlings and young plants properly
Our thoughts
Start Up does what it says on the tin — gets young plants off to a solid start without making you think too hard. It's organic, it's dosed dead simple, and growers consistently report proper root development right from week one. One we recommend a lot for anyone starting out with peat or coco.
Plagron Start Up is a complete nutrient solution for the growth phase, combining essential nutrients, a root stimulator, and natural growth hormones all in one bottle. Designed specifically for seedlings and young plants in peat and coco substrates, it takes the guesswork out of early-stage feeding. Just shake, measure, and apply — no mixing multiple bottles, no overthinking it.
How it compares
Start Up sits in the single-bottle, beginner-friendly bracket of nutrient solutions.
- All-in-one formula — no need to buy separate root stimulators or growth boosters
- Organic certified (Control Union) — appeals to growers who care about quality from seed stage
- Significantly cheaper than premium multi-part systems
- Peat and coco only — not designed for hydroponic setups, which keeps the price sensible
You're getting proven early-stage nutrition at a price that doesn't demand a second mortgage.
Usage guidance
Seedlings and rooted cuttings
Add 7ml of Start Up per litre of water. Apply once a week during the growth phase. Shake well before use — it's organic, so the ingredients settle.
Substrate compatibility
Works with peat and coco. Not designed for hydroponic systems like NFT, DWC, or aeroponics. If you're using an irrigation system, flush the pipes after use to avoid blockages.
Transition point
Once your plants have grown three pairs of leaves, you're ready to step up to a full vegetative or flowering nutrient (Plagron's Cocos A+B, Terra A+B, or equivalent). Start Up is the springboard, not the whole journey.
Storage
Being organic, the solution can spoil. Mix only what you'll use within 48 hours. Don't batch-mix for the week — it won't keep.

Who this is for
- First-time growers who want simple, one-bottle nutrition for the early weeks
- Anyone starting from seed or working with rooted cuttings
- Growers using peat or coco who don't want to juggle multiple products
- Budget-conscious cultivators who appreciate genuine value over brand names
- People moving over from other brands looking for better root development at a lower cost
Best suited to anyone who'd rather get the fundamentals right than experiment with complicated multi-part systems in week one.
Our take
This is a proper early-stage nutrient that does exactly what it should without overcomplicating things. Growers consistently report solid root development, and at this price point, it's a low-risk way to get the first few weeks dialled in.
Worth picking up if you're building a peat or coco setup from scratch. Once plants are established, you'll graduate to a bigger nutrient programme — but Start Up gets you there cleanly and without fuss. Good time to buy while stock lasts.
