GrowMax Power Grow 500 Reverse Osmosis System

Description

The GrowMax Power Grow 500 is a reverse osmosis system rated up to 500 litres per day. Reverse osmosis strips tap water back to almost pure water, so you start every feed from a clean, known base.

Why growers use it

  • Reverse osmosis water for complete control of your feed
  • Up to 500 litres a day
  • Takes standard 10 inch GrowMax replacement filters

Getting started

Connect to your mains cold water, run the first tank to waste, then collect RO water for mixing feeds. RO water has almost no calcium or magnesium, so add a cal mag supplement or use a soft water nutrient.

Filters: GrowMax 10 inch Replacement Filter Pack.

Delivery, returns and FAQs

Will my order arrive in plain packaging?

Yes. Every order is sent in plain, unbranded packaging as standard.

How quickly will my order arrive?

Order standard size items by 12pm on a working day and choose Next working day at checkout, and your order will be with you the next working day. Standard delivery takes 2 to 3 working days.

Bulky items such as grow tents, large fans and 50L bags of soil go by courier in 2 to 3 working days, or on a pallet for very heavy orders. Next day is not available for these, and if your basket includes a bulky item the whole order travels with it.

UK delivery is free on orders of £94.99 or more, except for bulky items. See our delivery page for full prices.

Can I collect from the shop?

Yes. Choose Click & Collect at checkout and pick up for free from our shop at Unit 2 Black Lake, West Bromwich, B70 0PJ. Orders are ready within 1 hour.

Can I return an item?

You have 14 days from receiving your order to tell us you want to cancel, then a further 14 days to send it back. Items need to be unopened and in a resaleable condition.

If you change your mind, the return postage is paid by you. If something arrives faulty or damaged, send us photos within 48 hours and we will cover the cost of putting it right. Full details are in our refund policy.
