Vitalize is the Mills silicon additive: a concentrated mono-silicic acid, the form of silicon plants take up directly, developed by Mills with silicic acid specialists Rexil Agro. Mills formulated it to make plants heartier and more resistant to stress, and it goes into the tank first, before anything else, at just 0.1 to 0.2ml per litre. It runs every feed from the first growth week to bloom week 6, at the same dose whether you mix with tap or RO water, and works with other fertilisers as well as the Mills range. It is strong stuff in the bottle, so read the handling note below before you open it.

Handle with care. Concentrated Vitalize is highly acidic (pH 0.5 to 0.9) and the Mills safety data sheet classes it as corrosive to skin and eyes. Wear nitrile gloves and safety glasses when measuring, keep it locked away from children, and rinse any splash off straight away. Once diluted at 0.1 to 0.2ml per litre in your nutrient tank it is fine to handle as normal feed. Do not tip the concentrate down the drain.
Silicic acid, not potassium silicateMost silica additives are potassium silicate that has to break down first. Vitalize is already mono-silicic acid, the form plants absorb.
0.1 to 0.2ml per litreThe dose is a fraction of a millilitre, so even the 100ml bottle goes a long way. Grab a syringe for measuring.
One dose for tap and ROUnlike the rest of the range, the Vitalize rate is the same on both Mills charts. No second set of numbers to track.
Growth through mid bloomEvery feed from growth week 1 to bloom week 6, building plant structure through the stretch that carries the weight later.
Works with other brandsBuilt into the Mills chart, but compatible with other fertilisers too. Add it first and it slots into most programs.

Grower's Tip

  • Vitalize always goes in first, into plain water, and gets a proper stir before anything else touches the tank. Mills is firm on this.
  • Measure it with a syringe, not a cap. At 0.2ml per litre a 10L can needs just 2ml.
  • Drop to 0.1ml per litre at bloom week 5 and stop after week 6. The Mills chart runs the last three bloom weeks without it.
  • Gloves and glasses on when you open the concentrate. It is acidic enough to burn skin, even though the diluted feed is not.
  • Keep the bottle somewhere cool and locked, between 5 and 30°C. A hot shed in summer is not the place for it.

Frequently Asked Questions

Why does Vitalize have to go in first?

Mills tells growers to add Vitalize to plain water first and mix it thoroughly before any other product. Follow that order every time: Vitalize, Basis A, Basis B, then additives.

Do I need gloves to handle Vitalize?

Yes. The concentrate has a pH of 0.5 to 0.9 and the Mills safety data sheet lists it as corrosive to skin and eyes. Wear nitrile gloves and safety glasses when measuring.

Is the dose different for tap and RO water?

No. Both Mills charts use 0.2ml per litre through growth and bloom weeks 1 to 4, and 0.1ml per litre in bloom weeks 5 and 6.

When do I stop using Vitalize?

After bloom week 6. The Mills chart runs bloom weeks 7 to 9 without it.

Can I use Vitalize with another brand's nutrients?

Yes. Mills lists it as compatible with other fertilisers. Add it to the water first and stir well before your base nutrient goes in.

What is in Vitalize?

Mono-silicic acid (tetrahydroxysilane) as the active, with boric acid, zinc chloride and copper chloride, according to the Mills safety data sheet.

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.
