FAQ: What Is Rdwc Hydroponics?

RDWC hydroponics systems (Recirculating Deep Water Culture) are an improved or “hybrid”way to grow crops versus static DWC (Deep Water Culture Systems). Plants grown in hydroponics, especially RDWC have unburdened access to water, oxygen and plant nutrients.

Is RDWC better than DWC?

Much like it’s cousin, the bubble bucket, the recirculating deep water culture system (RDWC, better known as DWC) quickly grows plants in a near ideal environment. The main difference is that the system supports multiple sites and allows you to grow a much larger crop of the same plant with far easier maintenance.

What is RDWC grow?

RDWC Application Recirculating Deep Water Culture is a method used to grow plants with roots submerged in a highly oxygenated nutrient solution. By using the ALIEN® RDWC hydroponic system, you can optimise maximum growth potential. The super oxygenated nutrient solution is constantly recirculating around the system.

How do RDWC systems work?

Recirculating deep water culture works by combining multiple individual deep water culture systems into a single system. Each of these systems is connected together with a series of pipes. This allows all pH and nutrient checks to be done at the same time, usually in a separate bucket called the control tank.

How do you grow RDWC?

1. Technique

  1. Rinse grow rocks/stones thoroughly before use.
  2. Fill the net pot to a 2” depth with rocks/ stones.
  3. Rest bare root cutting on rocks/stones and gently fill remaining space up to 1” from the top lip of the net pot.
  4. Adjust system water level to the top of root crown.

Does DWC increase yield?

FAST VEGETATIVE GROWTH AND BIGGER YIELDS Plants grown in DWC setups have easier access to oxygen and nutrients, which means they spend less energy searching for nutrients and developing roots. As a result, plants will reward you with fast vegetative growth and excellent yields.

How often should you change water in DWC?

Therefore, every 1-2 weeks (generally the longest you should wait before changing your nutrient solution is three weeks), you should remove your plants from the reservoir to replace and refresh the hydroponic nutrient solution, then place the plants back in the reservoir.

How many types of hydroponics are there?

There are seven types of hydroponic systems: the Kratky method, deep water culture (DWC), wick system, ebb and flow (or flood and drain), nutrient film technique (NFT if you like acronyms), drip system and aeroponics.

What is Bubbleponics?

Bubbleponics is a type of hydroponics that adds even more oxygen to the water by removing the reservoir from the plant. Since the plants are no longer sitting in the water, there is no risk of root rot. Bubbleponics uses airstones, similar to what you find in a fish tank, to add extra oxygen to the water.

Is Deep Water Culture a closed system?

Closed hydroponic systems include both simple hydroponic systems, as well as sophisticated ones. Here is a short brief of some of these methods: Deep Water Culture (DWC) hydroponic systems – This is the most simple type hydroponic systems.

What is aeroponic system?

An advanced form of hydroponics, aeroponics is the process of growing plants in an air or mist environment rather than soil. Aeroponic systems use water, liquid nutrients and a soilless growing medium to quickly and efficiently grow more colorful, tastier, better smelling and incredibly nutritious produce.

What is drain to waste?

Simply put, drain-to-waste is where you water your plants to a point where a recommended 15-20% by volume starts running-off, escaping the growing medium. This runoff water is discarded entirely. In a recirculating environment, the runoff is collected and used to feed other plants.

How often do you change water in RDWC?

A general rule of thumb is that hydroponic water should be changed out every two to three weeks. Depending on your system you may change it more or less often to maintain optimal pH and nutrient levels. The frequency with which you change your hydroponic water is important, but so is how you change it.

What nutrients are in RDWC?

This is a period of time where plant roots need medium amounts of Nitrogen levels, high Phosphorous levels, and medium Potassium levels. The FloraMicro solution targets the flowering stages of growth. During this period, plants need low Nitrogen levels, medium Phosphorous levels, and high Potassium levels.
