What is a Deep Water Culture ” DWC ” System?
If you’re a newbie to the Deep Water Culture System, it can appear to be quite overwhelming at first but, it’s really not that difficult or complex at all.
There are a number of other types of hydroponic gardening systems available but, this system is one of most popular with the plant’s entire roots system submerging in a very well oxygenated solution of nutrients and water and it typically grows in a reservoir that holds a generous amount of water.
The benefits of the DWC System
This traditional hydroponic system has very little assembly and moving parts but, once you’ve set up , it’s very low maintenance and has a very fast growing time as opposed to growing your plants in soil. I can grow lettuce in 30 days instead of 60 days growing in soil – double the time. The only downfall in the small systems may be the water level, pH, the nutrient concentration fluctuating and it can be very easy to over or under calibrate.
The easiest way to build the DWC system is with a 5 gallon bucket, an air pump, airline tubing and net pots. All you need to do now is connect a pump to the tubing and once you’ve done this, simply connect the tubing to the airstone, then place it into a bucket. The next step is to fill up the bucket with water with pH and the appropriate nutrients. Now, start your seeds!
Let’s see why the DWC System works
In no time, you will begin to notice that your plants begin to germinate and the roots will then touch the water with an explosion of growth. Your plants will easily suck up the water and nutrients instead of spending all their energy growing roots and searching for pockets of water in the soil. Due to the rich nutrient and highly oxygenated environment, this deep water culture system will provide you with a harvest in double the time than grown in soil.
As time goes by, most people tend to move from the traditional system to the Recirculating DWC in order to upgrade their gardens. The last thing you would want is to still be using 10 buckets and individually calibrating and adjusting them. It also makes much more sense to have only one reservoir that can feed the nutrient solution to all 10 buckets. Imagine torturing yourself by individually monitoring pH and calibrating all the buckets separately.
The recirculating system is brilliant and moves water from bucket to bucket and transports oxygenated water via spray nozzles. This modification simply generates more water, oxygenates and calibrates all the buckets from one central location.
What is Bubbleponics?
The Bubbleponic System does have its advantages even though it’s not really that much different to the traditional deep water culture system. The difference is that it speeds up the process of germination and the waiting time for the roots to touch the top of the water in the reservoir.
This is simply done by top feeding the nutrient solution for the first 3 weeks. What is happening here is the process of an additional water pump with drip lines that run up out of the tank to the plants that are sitting in the net pots. It is a very simple but effective process that speeds up germination and the seedling phase.
