Alien RDWC 8 Pot 20L Black Series

Product Description

Alien RDWC 8 Pot 20L Black Series is a highly oxygenating RDWC system from Alien. This type of hydroponic system has plants sitting in small net pots with roots hanging down into a pot below. Nutrient water is constantly flowing around the system into each pot housing the plant roots and back to the header pot again. The grow is standardized thanks to each plant receiving equal nutrition. Each pot has a Jet Stream Air Ring at the bottom forcing air through the water and dissolving considerable oxygen. Peak oxygenation provides consistent nutrient delivery for optimal results.

Key Features

• Threaded 32mm fittings
• Heavy duty pots
• Elevated airlines
• Square net pots
• Chiller ready

How It Works

Alien RDWC 8 Pot 20L Black Series is able to optimise your grow’s potential. The nutrient solution is heavily oxygenated and consistently circulating around the system. A current draws the solution through the pots mixing the nutrients via a water pump. Not only does this cater for vital nutrient delivery it also maintains PH and EC levels through the high water volume.

How To Use And Assemble Alien RDWC 8 Pot 20L Black Series

Assembly

Fit the 32mm threaded fittings into the holes at the bottom of the pots. The rubber washer must be on the outside then secure the nut with the spanner provided. Bird’s eye view images are provided to explain which fittings to use on 2, 3 or 4 row systems. Fit a 32mm straight to the header pot and cut a piece of 32mm pipe. Fit a 32mm barbed tee. The header pot can be located outside of the grow room, however you may need extra pipe. Heat the ends of the pipe in some hot water. This will make fitting easier. Note: The header pot is supplied with a single water pump for recirculating the system. If using a water chiller, a separate water pump is required and can be installed. Follow the chiller manufacturers recommendations for pump sizing. Place your pots in the desired location and measure the distance between the barbed fittings. Take note of the maximum recommended pipe lengths. Cut and fit the 32mm pipe. The black 19mm pipe connects the reducing tee or tees to the green hose tail on the header pot. As a guide: 20L pots are recommended for 4 pots per square meter. 36L pots are recommended for 4 pots per 1.2sqm. Examples: 2 x 2m tent – 16 pot 20L system 2.4 x 2.4m tent – 16 pot 36L system Fit the rubber elbow to the Jet-Stream air pump and secure with clips. Place the air pump in the desired location, preferably raised above the pots to avoid water returning to the pump in the event of a power cut. Fit a piece of 16mm pipe inside the rubber elbow and secure with the clip. Fit a 16mm tee in line with the first row of pots. Fit the pot clips to the slot on the side of the pots. Run a piece of pipe from the tee up to the pot clip and fit an airline connector. Complete the airline along each row and put a 16mm blank at the end of each line. Place one air stone and sucker in the bottom of each pot and connect the stone to the airline connector with 4mm pipe. Place the lids and net pots in position. If your system is the 36L version then you also have the lid surrounds.

How to Use

Use a hose pipe to fill the system. When the float valve in the header is level, the system is full. Do not turn the water pump on until the system is at least half full to avoid an airlock in the water pump. At this stage, the CAMO® Tank can remain empty as small plants have enough nutrient solution in the system to support them for some time.

Adding Nutrients

Add nutrients directly to the header and let the system recirculate for some time before taking a reading. Adjust accordingly. Do the same for PH down. Ideally, let the system recirculate overnight to allow the water to reach a habitable temperature for the plants. Cold water can shock the plants.

Planting into the system

Put a layer of substrate into the bottom of the net pot level with the raised grid. Water the cutting before transplanting. Place the rooted cutting into the pot and fill the remaining void with substrate.

Draining the system

To perform a nutrient change or to drain the system, simply connect a pipe to the barbed fitting on the recirculation pump. To refill the system, you can use the CAMO® Tank to prepare a fresh batch the day before or if the tank isn’t large enough then you can directly fill the system with a hose pipe as long as the water is at least 17 degrees so to avoid plant shock. If using the hose pipe method add a small amount of nutrients to the header as the system is filling.
