Long Description

DWC Hydroponics offer deep water culture systems that produce amazing results with very little maintenance.


Alien recirculating deep water culture (RDWC) XL system create fantastic foundations for you to produce large and healthy plants. The system allows the oxygenated nutrient solution with consistent pH and EC levels to reach your plants continuously. Considered to be a ‘plug in and grow’ system because it doesn’t require any electronics or growing media.

The range goes from a 4 pot system up to a 48 pot system. 

Includes a 100 ltr tank, 30ltr pots and 32mm pipes. 

This system is the XL version which features larger 30 litre pots whereas the standard system uses 20 litre pots.

How it works

The gentle flow of water passes underneath the 100mm mesh pots allowing vital nutrients to reach the roots. This flow optimises health of the root zone and increasing nutrient uptake efficiency.
The 20 litre pots are linked together with a row of 32mm pipe and fittings whereas the XL 30 litre pots are linked together with two rows. This allows for a free flowing system, recirculating the nutrient solution seven times an hour. The larger diameter pipe also helps address the issue of the roots blocking the pipe. Air lines are connected to each pot to aerate the solution.

Air kits

Our XL air kits include the Enviro ET series air pumps which are a very high quality super silent pump, 100mm air stones and the air lines are our own alien green flexible PVC which does not kink like cheap silicone comparisons. The 20 litre kits use Hailea V series pumps which are also silent.


The Budbox Aqua Tanks that we supply are a collapsible water tank allowing the whole system to fit through tight spaces where other bulky plastic water butts cannot. The Aquatank comes flat packed so the entire system fits neatly into a cardboard box allowing for easier transportation. The material is non toxic and 100% lightproof.
The Aqua tank is connected to the header pot and by means of a adjustable float valve the nutrient solution level is automatically maintained. You can raise or lower the nutrient solution level in the entire system to suit your plants requirements.

Set up

To keep system set up time to a minimum the pots have pre-punched holes. With each system a pair of quality pipe cutters are provided so no tools are required. We use our own specially designed grommets to ensure secure and water tight connections. The entire system is simply push fit.
