What’s the difference?
DWC (deep water culture) is a hydroponic growing method.
DWC = Deep Water Culture
R-DWC = Recirculating Deep Water Culture
Both methods use bubblers – a kind of pot. In these pots, roots grow straight into an oxygen rich nutrient solution.
To keep your nutrient solution oxygenated, you need to use an air pump, airline and air stones.Most DWC and R-DWC Systems come with them - all except the IWS R-DWC System where you need to buy an air kit.
Hardly any media is needed (just clay pebbles). This means roots get instant and unlimited access to nutrients & oxygen!
• Fast nutrient uptake
• Bigger, healthier roots
• Bigger yielding plants
On top of this, nasty root diseases can’t survive in an oxygen rich environment.
Nutrient solution is static – it stays in whatever bubbler you put it in.
You can use standalone bubblers (like an IWS Oxy-Pot). If you want to, you can keep several OxyPots filled from one tank, but if you're going to do that, you may as well get an R-DWC system. You'll get better results if you do.
Instead of staying in one pot, your feed constantly travels round your entire system, mixing and cooling along the way.
Which Option is Right for You?
If you’ve never used a hydro system before, DWC is a great place to start.
You don’t need to go big – it’s as simple as swapping your standard pots for an Oxy-Pots. You can fill several pots from one tank. You can connect multiple air stones to one air pump to keep costs low too.
There’s also loads of margin for error with DWC – great for beginners!
Unless you use a remix timer, nutrient doesn’t travel from pot to pot. This means that if you do get a problem (like Pythium), it’s easier to stop it spreading.
• Option 1: IWS Oxy-Pot (small & easy to manage, great for beginners.
• Option 2: IWS Oxy-Pot XL (twice the size of a Oxy-Pot - for 1 big plant or two medium sized plants)
• Option 3: IWS Oxy-Pot 4 (Space for 1 large plant, 2 big plants or 4 medium plants)
For best results, go R-DWC! As your nutrient recirculates, it mixes and cools!
Your feed doesn’t get the chance to stagnate. With all that mixing, your pH, temperature and CF stays stable… oxygen levels are much higher too.
Ultimately, you’ll get a much bigger yield.
• Option 1: IWS R-DWC System - Recirculating (great price, smaller for tighter spaces, shop favourite)
• Option 2: IWS R-DWC System - Recirculating & Dumpback (also manages your nutrient)
• Option 3: IWS RUSH (best results, faster recirculation, bigger pipes, powerful pump)
IWS RUSH Systems (R-DWC)
It’s the Rolls Royce of all bubbler systems.
Why’s it so good? The clue’s in the name – RUSH.
Recirculations are stupidly rapid - this monster’s got 63mm pipes and a powerful pump!
Feed is whipped around at lightning speed, (up to 34 full circulations an hour)! Imagine how much oxygen gets trapped!
With all that oxygen, nutrient uptake soars. You’ll get giant roots, faster growth, bigger yield – the lot.
You won’t find a system better than this.
