Build Cheap 2 Liter DWC Hydroponic System for clones.

Many people have the impression that hydroponic systems have to be either expensive, complicated or both,
but that's not necessarily the case.

Hydroponics is simply a method of growing plants without using soil, and any system that will give the plants what they need is a system that will work.

There are many different ways to set up a hydroponic system,
but one of the easiest is to use water bottles as the foundation.

You can make an easy, effective DIY DWC setup by using pop bottles for little cost.


Cut bottle 7 inches from the bottom.
Make sure to wash Your pop bottle to get rid of any bacteria.


The Air stone is going to go in something like this.


Drill a hole and stick the air stone in it.
After you put the air stone in, connect the tube to it.


Then drill some holes in the cap for the water in the reservoir to reach the Perlite.


Stick the top part of the 2 liter in the bottom part so they fit together.


Fill up the top part with Perlite then add water.
Distilled and Deionized water is best.


Now connect the other end of the tube to your Air pump.

Stuck an unrooted cutting in it to see what happens.
Take another top of a 2 liter and stuck it on top as a humidity chamber.


After 2 weeks roots are long enough for a soil transfer.

Cleanup and Maintenance

You will have to change the water in Your reservoir every few weeks,
as the plant grows, it starts to exhaust the nutrient supply.

Also be sure to check water level every couple days,
making sure it is not to low and is limiting the plants access to water,
and top it off as needed.

Watch out for Algal infestation

If You let light into the nutrient reservoir it is only a matter of time before the Algae and
also fungus move in. Perlite, especially in a humid environment, is a media that Algae does very well on. Paint the bottles black, but there is a risk of getting paint in your root zone, which could result in chemicals in your Veggies.

Things you will need:

Most can be found at your local Wal-Mart type store in the aquarium section.

• 2 liter pop bottle ($1)
• Perlite ($2-$7)

• Aquarium air pump ($5-$10)
• Air stone ($1-$2)
• Tubing ($2-$5)

Total cost to make this is between $11 and $22
depending on where you live and what you get.

The purpose of the Air Stone is to Oxygenate the water, this provides oxygen to the roots, which is essential for healthy plant growth, otherwise You would drown the plant.


You Can Use Hydroton (expanded clay pebbles) as a Growing Medium.
It works great and it really cheap. You Can mix it with Coco fibers.



Expanded clay is considered to be an ecologically sustainable and re-usable growing medium
because of its ability to be cleaned and sterilized, typically by washing in solutions
of white vinegar, chlorine bleach, or hydrogen peroxide (H₂O₂), and rinsing completely.
