The Growmax 3000 Reverse Osmosis Filter is a 3 stage RO filter that can deliver up-to 125 litres per hour of low EC, nearly pure water - total output of the filter is up-to 3000 litres per day.

  • Removes up-to 95% of potentially harmful contaminants
  • Reduces water hardness, giving increased control when feeding
  • Effective for around 40,000L, or around 6 months
  • RO water allows beneficial soil biota to flourish

Using eco-friendly coconut fibres with increased absorption capacity, the system effectively removes up to 95% of:

Chlorine, salts, heavy metals, chloramines, nitrates, nitrites. Sediment; dirt, rust, oxidation. Herbicides, pesticides, volatile organic contaminants (VOCs - chemical contaminants, benzenes, toluene, oils, THMs, detergents and PCBs).

Using RO water has a number of benefits - Firstly, removing the chlorine and other contaminants lets the soil biota flourish, especially if you are using bacterial or microbial additives. This ensures optimal nutrient uptake, keeping plants happy and thriving. RO water also delivers a stable pH of around 6.5, a good starting point for most plants. Thirdly, RO water allows for more precise control of fertilization by removing the background EC of your tap water, enabling you to deliver your plants a more balanced nutrient solution.

The filters on the Growmax 3000 last for around 40,000 litres or 6 months. We list the replacements in the dropdown above, along with a replacement membrane - this will need changing approx. every 9 months. Other accessories available include a float switch and booster pump for use where the input to the RO filter is less than 40 psi. Using 6mm piping and fittings, the Growmax 3000 Reverse Osmosis Filter outputs up-to 3000L/day, however if this does not quite meet your needs, please check out our full range of water filtration options here.

Good quality
Size: 3X-Large, Color: White
The shirt fit great! True to size. Only issue for me, it would have been nice if it was longer to tuck in.

Great shirts! I prefer them over much, more expensive shirts!
Size: X-Large, Color: Lemon Yellow
Nice fitting shirt for the cost. Better than most that I’ve purchased for 2-3 times the cost. I prefer these to my Lacoste or Lands End long sleeved shirts! They look/wear much nicer after dry cleaning versus machine washing. I’ve bought five of them now!

Measurements just didn't add up.
Size: X-Large, Color: Sky Blue
Quality of the shirt was nice but the measurements did not add up. I wear a 17 1/2 neck and 36/37 or 37/38 sleeve. I ordered an XL and the sleeves were a little to short and the neck was way to big. Could never wear a tie with this shirt. So going up in size wasn't an option because of the neck. The next size up that had longer sleeves was a 3X, not happening. So if I went down in size the sleeves still would have been to short and the shirt would have been to tight. If the shirt fits you then you have a good shirt at a great price with lots of colors.
