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.
Specifications
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.
