Deep Water Culture (DWC) Bucket Quality
Plants, and especially cannabis require pure and un-tainted nutrients for plant growth. Contamination is often a concern. It is wise to sterilize your hydroponic system before growing to reduce plant-killing bacteria.
Some growers go as far as adding bacteria that are beneficial to plants.
Either way, you prepare your bucket or reservoir you will also want it to be opaque as to not introduce light into the bucket. This can harm nutrients as a result.
DWC System Mesh Baskets
Plants are placed into mesh cups also known as baskets, along with rockwool soil or peat moss. The “fill” should use the highest quality moss or soil you can purchase.
This is like an ambilocal cord for your plants. You will want it to transport your top-quality nutrients with ease and without contaminates to not spoil your growing potential.
DWC Air Pump Quality
The Air pump in your deep water culture system is extremely important to your indoor garden’s growth. The air pump pushes oxygen into the plants’ roots.
This ensures the plants get the oxygen they need without suffocating. A constant flow of oxygen is vital.
The air pumps continuously run, making noise along the way. Some run quieter than others but typically have a higher cost for this feature.
DWC System Growing Tips
- Temperature – This is one of the items you will want to monitor as much as possible. The water supplied through your hydroponic system should be an optimal 60 to 70 degrees.
- Using LED grow lights helps as they tend to remain cooler. Even if you run a cool grow light in this range, you should always check your water temps using a simple thermometer.
- PH Balance – Every week at minimum, checking your PH levels that your plants absorb is a wise choice. A good PH for cannabis should fall between 5.5 and 6.5 pH levels. This is where cannabis likes it – slightly acidic.
- Nutrients – Food for your plants. All the minerals they love should be included in the water supplied to your plants. A once a week addition of new nutrients to your water supply is recommended. You can perform this as you check the water temps and the pH levels of your plants to make it easier.
Hydro Pots, Bubbleponics, and Deep Water Culture Systems
They go by many names but they are all the same thing. Beginners in growing plants indoors and outdoors find them easy to use. Other than once a week maintenance and nutrient checks, they are easy to set up and affordable.
A basic DWC system requires 3 items:
- A reservoir/bucket to hold your nutrients and water.
- Mesh cup that holds your plant within its foundation which is typically your peat moss or rockwool soils.
- An air stone that provides healthy oxygen to your plants’ roots.
For every plant you grow you will need one hydroponics system for each. The plant itself is suspended above the water in the mesh cup which allows the roots to submerge beneath the nutrient-rich water and grow towards the air stone.
Multiple plants have been considered by DWC manufacturers and contain multiple buckets yet share the same water supply to make things easier. If you are experimenting with nutrients you may want to purchase multiple separate hydroponic systems to isolate better nutrient levels between individual plantings.
The deeper the water the better. You will want a deep bucket because this allows nutrient levels to stabilize easier. “Deep” water is easier to manage and fewer changes to your eco-systems.
Advantages of Deep Water Culture
- Big and healthy yields for your crops
- DWC’s are easy to use, especially after the initial set-up.
- Expandable for many hydroponic systems should you want to grow more
- Beginner-friendly all in one solution
Cons With A DWC System
- Keeping the temps at a standard
- Loss of electricity will kill your plants fast
- Need a backup Reservoir in case of failure of the first
- Pumps can add to the noise level in your grow room
Final Notes On DWC Sytems
Those who are new to indoor gardening might still think that soil is the only way to grow plants which is simply not true. The purpose of soil is to provide nutrients, but with a DWC system setup, the water acts as the supplier of nutrients into the root system of the plant and skips over needing soil to begin with.
A DWC system is a cheaper alternative to fancier hydroponic systems on the market and allows for easy integration in a grow tent. Maintenance is easy and the results from a DWC hydroponic system will give you larger plants grown in less amount of time versus growing plants indoors in soil.
A DWC system versus soil will also rely on checking on your cannabis plants more often to ensure things are working correctly. The rush of nutrients that a hydroponic system setup provides can result in overfeeding plants, nutrient burn, and poor results if you are not paying attention.
1. Does DWC increase yield?
Growing plants in DWC setups improves their access to oxygen and nutrients, which means they spend less energy searching for nutrients and developing roots. Plants will reward you with fast vegetative growth and excellent yields.
2. How often add nutrients to DWC?
If you are using a DWC system, it is recommended that you add nutrients every time you top up the reservoir. If your plants are growing well and there are no algae in the tank, then this should be done once per week.
3. How much does DWC yield?
In a DWC, a ph level of around 5.8 is typical for vegging cannabis. For many cannabis growers, DWC is the ideal complement to SCROG. When grown from an auto-flowering seed or a feminized cannabis seed, DWC and SCROG training allow plants to grow to their maximum potential, enabling yields of several hundred grams per plant.
4. What should my PPM be in DWC?
There is no one-size-fits-all answer to this question, as the PPM (parts per million) needed for optimal growth in a DWC hydroponic system will vary depending on factors such as the type of plant, the size of the plant, and the climate. However, a PPM of around 400 is generally recommended for cannabis plants in a DWC system.
5. What is a DWC system?
DWC stands for deep water culture. A DWC system is a type of hydroponic system that uses a reservoir of water to grow plants. The plants are suspended in the water and their roots grow down into the nutrient-rich solution.
