Reviews From Our Gardener's

Wow, noticeably better growth and excellent value
(read about my comparison)


I’ve been growing a range of plants in my hydroponic setup, mostly lettuce, kale, and spinach, and after switching to these nutrients, I’ve seen a huge improvement in growth and overall plant health. Everything in my setup stayed the same: lights, trays, timer, etc, so this was a fair comparison, and the difference was clear. My plants are growing faster, look more vibrant, and seem much healthier than when I was using the smaller bottle of nutrients that came with my kit. The cos lettuce (same seeds) also ‘stronger’ if thats possible!

These bottles are also great value for the volume you get. It’s easy to see why they come up as an Amazon recommendation. I didn’t realise how much of a difference nutrient quality could make until now.

I’ve attached a photo of my current setup (at about 4 weeks) so you can see the results for yourself. This is only half grown, I have run out of room. I think they are growing about 30% faster. Highly recommend this if you’re serious about getting better growth from your hydro system.

FAQ

A & B formulas are separated to prevent nutrient lockout and ensure maximum absorption. This method is used by commercial growers for precise, stable results.
Yes! While designed for hydroponics, this formula works just as well for pots, garden beds, and even fruit trees. Just dilute as directed and apply regularly.
The approximate NPK is 25-6-40 — high in Nitrogen and Potassium for rapid vegetative growth, with enough Phosphorus to support strong roots and overall structure.
Most general fertilisers contain filler and limited nutrients. Ours delivers pure commercial-strength minerals, with macro and micro nutrients for full-spectrum plant health.
