Tired of feeding your plants every few weeks? Well check out our Slow Release Fertiliser!

We’ve been working hard to find the best possible fertiliser to complement our Semi-Hydro mix, and we’ve developed an 8–9 month slow release formula that provides all the required nutrients and minerals for strong root support and healthy plant growth. With a hearty NPK of 11-21-9 + 6% Mg, it’s packed full of essential nutrients to help your plants thrive.

This fertiliser can also be used in most soil mixes, making it a versatile option for a wide range of setups!

Please note:

Do not use any additional fertiliser alongside Slow Release, as it is designed to be a complete feed on its own.

Maximum recommended dosages: 2% of total mixture volume. For further advice, feel free to contact us.

Purchase a very good set or at least the correct cutters for this wire. I’ll make your life hell .
Glad I bought it when I did. Copper has gone way up. And this is full core copper. Place my copper ends on the stuff works great. Using it on a solar battery bank.
