Best DWC System For Growing Cannabis: Deep Water Culture Reviews 2018

dwc systemA DWC system is the next step for those wishing to expand their growing capabilities with a system that ads timely nutrients to plants. DWC systems do exactly that; They allow a steady supply of nutrients and water to enter your plants ecosystem at a rate and frequency that you can set manually.

The results from a DWC system are proven to grow cannabis quicker than that of basic soil grown plants. The increased plant growth is a result of supplying plant nutrients exactly when a plant needs them, especially during the vegetative stage of growth to increase their strength and growth rate dramatically.

There are a couple of things to keep in mind before growing with Deep Water Culture Systems but don’t worry. We will walk you through just what a DWC system does and what to look for when buying a DWC system.

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 system before growing to reduce plant killing bacteria. Some growers go as far as adding bacteria that is 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 grow. 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 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 it 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 DWC 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 DWC 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 less changes to your eco-systems.
