Not All Silica Is Created Equal.

Silicon is one of the most useful things you can give a plant.

The catch? Most of it arrives in a form plants struggle to use. It’s a bit like being handed a cheque you can’t cash.

Mills Vitalize is different. Its patent-protected mono-silicic acid is water-soluble and biologically available, so plants put it to work within 24 to 36 hours.

Mills were the first to offer silica in this form. Once you’ve tried it, it’s very hard to go back.



Built Like A Brick Outhouse.

Vitalize thickens cell walls, giving you fatter stems, sturdier branches and a robust frame that can carry more weight.

Better structure. Bigger crops.

Tougher walls also make life miserable for sucking and biting insects, while Vitalize helps plants cope with heat stress and resist mould and mildew, including botrytis.



Greener, Practically Overnight.

Better nutrient uptake means greener, healthier leaves and plants that consistently reach higher yields of higher quality.

It helps young roots too, by improving calcium uptake. And it won’t upset your pH.



Use A Little. Benefit A Lot.

This is properly concentrated stuff, so a syringe is your new best friend.

Add 0.2ml per litre in veg and the first four weeks of bloom, then 0.1ml per litre after that, and stop for the final flush. Always add Vitalize to the water first and stir before anything else.

It also works as a weekly foliar spray.

Small bottle.

Big personality.
