Battle of the Bubblers...DWC vs. R-DWC
DWC and R-DWC are both great growing methods. But which one's right for you? Find out now.
What’s the difference?
DWC (deep water culture) is a hydroponic growing method.
- DWC = Deep Water Culture
- R-DWC = Recirculating Deep Water Culture
With Both Methods
Both methods use bubblers – a kind of pot. In these pots, roots grow straight into an oxygen rich nutrient solution.
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 Oxypot). If you want to, you can use multiple Oxpots and manage them individually. To keep several Oxypots filled from one tank, 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?
It depends on how many plants you're growing and how expreienced you are.
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 Oxypots. You can connect multiple air stones to one air pump to keep costs low.
There’s also loads of margin for error with DWC – great for beginners!
Nutrient doesn’t travel from pot to pot, so you do get a problem (like Pythium), it’s easier to stop it spreading.
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.
If you're growing lots of plants, a system like this is much easier to manage.
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, a bigger yield – the lot.
You won’t find a system better than this.
