Start-R is the Mills additive for the start of a crop: seedlings, rooted cuttings, young plants and fresh transplants. It carries two forms of nitrogen, which lifts the nitrogen in your Basis A&B feed while plants are building roots and leaf, plus Irish kelp, humic acid, fulvic acid and L-amino acids in the same bottle. NPK is 5-0-0.5. You run it for the two growth weeks and the first two weeks of bloom at 1 to 2ml per litre, then it drops off the chart when C4 takes over. It is an additive, not a stand-alone feed, so it goes on top of a base nutrient.

Extra nitrogen when it countsTwo forms of nitrogen push the N in your feed up through early growth, without swapping to a separate grow base.
Four additives in one bottleIrish kelp, humic acid, fulvic acid and L-amino acids together, instead of buying and dosing each one separately.
Made for the first weeksMills lists it for seedlings, rooted cuttings, young plants and transplanting, the stages where a slow start costs you the most.
Low dose, short window1 to 2ml per litre for four weeks of the run. A 500ml bottle is enough to see what it does before you commit to a bigger size.
Designed around Basis A&BMills built Start-R to sit on top of its own two-part base, with doses set week by week on the same chart.
Any mediumRuns in hydro, coco and soil, the same as the rest of the Mills range.

Grower's Tip
  • Start-R goes in after Basis A and Basis B, never before. Mills' order is water, Vitalize, A, B, then additives.
  • Shake it hard before measuring. The kelp and humic content can settle in the bottle between feeds.
  • Keep it going through transplant. Mills lists transplanting as one of the jobs it is made for, so do not drop it the week plants move up a pot.
  • Stop after bloom week 2. That is where C4 comes in on the Mills chart and Start-R's job is done.
  • RO growers run it a touch higher in early bloom: 1.5ml per litre against 1ml on tap water.

How To Mix It
1Fill your reservoir or watering can with water.
2Add Vitalize if you use it, then Basis A, then Basis B, stirring well after each.
3Shake the Start-R bottle, measure this week's dose from the chart below and stir it in.
4Check EC, then adjust pH to 5.5 to 6.5 last.

Frequently Asked Questions
Can I use Start-R on its own without a base nutrient?

No. Start-R is an additive with an NPK of 5-0-0.5. Mills designed it to go on top of Basis A&B, which supplies the full range of macro and micro elements.

Can I use Start-R on rooted cuttings and seedlings?

Yes. Mills lists seedlings, rooted cuttings, young plants and transplanting as the jobs Start-R is made for. The chart starts at 1ml per litre in the first growth week.

When do I stop using Start-R?

After bloom week 2. On the Mills chart Start-R runs for the two growth weeks and the first two weeks of bloom, then C4 takes over.

Does Start-R work in soil and coco?

Yes. Like the rest of the Mills range, it is used in hydro, coco and soil.

How much Start-R do I use per litre?

Between 1 and 2ml per litre. Growth week 1 is 1ml, growth week 2 is 2ml, and bloom weeks 1 and 2 are 1ml on tap water or 1.5ml on RO water.

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
