Saving The Best Till Last.

Every season builds to a grand finale.

In those last few weeks of flowering, fruit swells, ripens and fills with flavour, and your plants’ appetite for phosphorus and potassium goes through the roof.

This is the final lap.

Mills Ultimate PK is the fuel.

Phosphite. The Clever Bit.

At its heart is phosphite, an extremely bioavailable form of phosphorus that plants take up quickly.

Teamed with potassium and chelated micronutrients, it supports healthier roots and better nutrient uptake just when your plants are working hardest.

Mills use clean, highly soluble mineral salts, so it dissolves properly and leaves minimal residue behind.

Your drippers, pumps and pipes will thank you.

Bigger. Harder. Heavier.

This is the bit you’ve been waiting for.

Larger, harder, heavier fruit, with more essential oil production for richer flavour and aroma.

Tomatoes, peppers, chillies and aubergines finish the season with a proper flourish.

Handle With Respect.

Ultimate PK is extremely concentrated, so a little goes a long way.

Start at 2ml per litre from week 5 of flowering, rising to 2.5ml per litre from week 7, running alongside Mills C4 for the first couple of weeks.

Don’t combine it with other PK boosters. It really doesn’t need the help.

And keep it away from frost.
