Every Champion Starts Young.

Every great harvest has an origin story.

And it almost always begins underground, weeks before anyone notices.

A plant with a big, healthy root system can drink more, feed better and carry far more weight later on. A plant without one spends the whole season playing catch-up.

Mills Start-R exists to make those early weeks count, from the very first week of growth right through to the second week of flowering.



Nitrogen. Twice Over.

Start-R carries 5% nitrogen in two forms, including ammoniacal nitrogen. That’s the fuel for lush leaves, sturdy stems and an extensive, highly absorptive root system.

Then come 18 L-amino acids, which help with protein and chlorophyll production, ease stress and boost nutrient uptake.

Think of them as a personal trainer for your seedlings.



Part Organic. Part Mineral. Entirely Clever.

With 85% organic matter, Start-R blends the best of nature with the precision of a mineral feed.

Humic and fulvic acids help plants drink up more water and feed while conditioning the growing medium. Cold-pressed Irish kelp (Ascophyllum nodosum) brings natural auxins and cytokinins, helping balance fresh top growth with healthy lateral roots.



Transplant Shock? What Transplant Shock?

Moving young plants into bigger pots is a bit like moving house. Exciting, but stressful.

Start-R helps them settle in quickly, so they get back to growing rather than sulking in the corner.

Add 1ml per litre from week 1, alongside Mills Basis A+B, and watch tomatoes, chillies, salad crops and houseplants get off to a flying start.

Strong roots.

Happy plants.

Bigger harvests.
