It's a shame that percentages bring you to such conclusions. Poor marketing, maybe. Is that really worthy of a neg? Overall the product on offer is great value for those in need. What's your agenda?
I just bought one, hoping it makes gardening more fun.
thank you, appreciate the support! This will make your plants thrive
Let me know if you have any questions on how to get the most out of it
Keen to see how your garden goes
will this help with buffalo grass?
Hey,
yeah, it's great for buffalo grass. Use the standard rate (4ml per litre) every 2 to 3 weeks for healthy growth and colour & apply during the cooler parts of the day if possible
Any benefits of this over charlie carp liquid fertiliser?
https://www.bunnings.com.au/charlie-carp-5l-all-purpose-conc…
hey, yes there definitely are:
first would be that Charlie Carp’s 10-1-6 ratio is pretty unbalanced for most plants — it’s heavy on nitrogen but low on phosphorus and potassium. Ours is a more balanced 20-20-20, which supports better overall growth, including roots and flowering. It’s also more concentrated, so you use less. Plus, we include essential trace elements which should not be overlooked and there’s no strong odour to deal with.
Let me know if you have any more questions
Thank you. Got one
Thanks for the support! Let me know how it goes or if have any questions, always love seeing what people are growing with it
It sounds like good stuff! I've been using Powerfeed, liquid potash and dynamic lifter for my chilli plants and this looks to be more cost effective for my needs.
4L is a lot though and liquid fertilizers degrade once opened. How long does it last once opened before it starts to degrade?
Would buy this immediately for 4 x 1L bottles!
Hey,
appreciate that!
The fact that it’s a mineral-based formulation, not organic like fish or seaweed products. These types of fertilisers don’t break down the same way, they are made from stable, water-soluble salts (like urea, potassium phosphate, etc.), which have very long shelf lives
so it lasts at least two years once opened since it's a stable, mineral-based formula with no organic ingredients to break down or start to smell - it will have the same effectiveness as when you first opened it
