    Good for ornamental trees?

      Good for plastic house plants and Christmas trees

      It would do great for ornamental trees — it provides balanced nutrition that supports strong roots, lush foliage, and vibrant blooms.

    Any deals on bright lights? shifty eyes

      Hey, currently we only offer plant fertilizers, but we're definitely looking to expand into other gardening needs - including high-quality accessories like lights

    I like the NPK mix, does this come with a 20L drum tap valve port?

      Hey, our 20L drums come with a standard screw cap - but we’re happy to include a tap attachment (free of charge) if you need one. Just leave a note at checkout or contact us after ordering

    Does this have a use by date?

    • AssociatedCompleteGrow @ CompleteGrow on 28/06/2025 - 12:53

      Essentially no. our fertilisers are made from stable, water-soluble salts (like urea, potassium phosphate, etc.), which have very long shelf lives and do not lose effectiveness. They don’t degrade like organic products ( seaweed or fish based), so there’s no real “expiry” date if stored properly.

        OK thanks, 20l probably too much for me. Might try the 4ltr

          thats fair, let me know if you have any further questions

            @CompleteGrow: Ordered as my usual powerfeed is running out. Let's see how it goes

            • AssociatedCompleteGrow @ CompleteGrow on 29/06/2025 - 09:55

              @0 0 0: Thanks for the support! Let me know how it goes or if have any questions

  • stewface on 30/06/2025 - 07:24

    Can you explain the difference to me between other bulk products like this?

    https://specialistsales.com.au/shop/turf-domestic/fertiliser…

    They sell so many different options too way above my pay grade for understanding what does what

    • AssociatedCompleteGrow @ CompleteGrow on 30/06/2025 - 14:00

      hey great question so the LiquiMaxx GreenMaxx K is turf-only, it’s missing Phosphorus (P) so not ideal for root or flower growth. Great for lawn greening, but not a full fertiliser like NPK 20-20-20.

      Ours is a balanced full spectrum fertiliser NPK 20-20-20 + micros which is for leaf, root, and flower growth in all plants, not just turf.

      hope that makes it more clear let me know if you have any more questions

      Ours is a balanced full-spectrum fertiliser (NPK 20-20-20 + micros) — perfect for leaf, root, and flower growth in all plants, not just turf. Great value for gardens, veggies, hydro & more.

        Thanks! Sounds like it’s what I need!

        How long does the sale go for? I’ll need to save for a bit, it’s a big investment for my garden.
