Hydroponic Wick System: Build a Worthwhile Wick System in 15 Minutes!

Wick System

Hydroponic Wick System DIY. 

The Hydroponic Wick System is the second most simple hydroponic system to build! The Hydroponic Wick System is very similar to the Kratky method hydroponics and also has deviations and additions, but we will show you the easiest one first.


The Hydroponic Wick System uses passive hydroponics irrigation. That means it does not require a pump, an air pump, or any electricity to work.


Need more info? Take a step back and learn more about the system or check out some other Kratky Method designs before you jump in to start your build.



  • You will need a Countertop or window sill near natural light for your Hydroponic Wick System
  • Reservoir ( choose 1 of the following options)
    • Mason jar (with lid)
    • Mug
    • Cup
    • Beer or wine bottle
    • Plastic bottle 
    • Plastic yogurt or similar container 
  • Net cup
  • Medium
  • Some material to be used as a Wick 
    • Torch wicks
    • Felt
    • Most types of rope
    • Cut pieces from an old mop head
    • Cut pieces of fabric from old clothing or linens
    • Yarn

  • Tap Water
  • Plant
    • Fresh Plant cutting (if you are cloning a plant)
    • Seedling
    • Seeds in a net pots and starter plug (we will show you this option later)



  • None!
  • You may need a Power drill  for some options below





This is a great example of how to upcycle a plastic bottle for great use!



  • Clean and Place the selected reservoir
  • Discard lids
  • Fill the reservoir with approximately 2/3 tap water



Cut your choice of wicking material a little longer than 2x the length long enough to reach from the bottom of our mason jar up to the bottom of the net cup (when the net cup is placed in the top of the jar) Pull the wicking material through one side and out the other side of the bottom of the net cup. make sure the length of each end sticking out is about the same. 





You have 2 options here, but It will depend on the type of reservoir you have. If you have a mason jar the following options will work. If you use one of the net cup options it is important that you buy the correct size net cup so the top of the cup rim fits either in the mason jar lid or directly on the top of the jar without falling in.


Option 1 – You may or may not need the mason jar lid. It will depend on the size of your mason jar and the size of your net cup. Place your choice of growing medium into a net cup over the wick. Place your cloned plant or seedling into the medium and carefully pour more medium around the base of the plant.


Option 2 – You need the mason jar lid here too. Place your seeds into a starter plug. Place your starter plug into a net cup. Fill any remaining space of the net cup with medium. Place the net cup into the lid of the mason jar or directly on top of the jar, whichever fits best.

More Options

Want to grow bigger plants? Don’t have a good location near natural sunlight? Use a larger reservoir to super-size it. Add a plant light with a timer to gain full control over your plant’s lighting conditions. Add aeration to make your Kratky system a Deep Water Culture system that will provide even more oxygen to the roots and really watch your plant grow!


Reservoir Options

  • 5-gallon bucket
  • Storage container (more options on this on our Deep Water Culture page)
  • Fill the reservoir with approximately 2/3 tap water
  • Just about anything that will hold water



  • Place air pump
  • Attach supplied air pump hose to the air pump
  • Attach hose inline backflow valve ( this is necessary to prevent reservoir water from backflowing into the air pump)
  • Attach a small air stone and place it into your reservoir ( you may need to punch or drill a small hole if your reservoir has a lid)



  • Follow manufactures lighting installation instructions to install a small full-spectrum LED light (Learn more about the LED lighting type you will need and how far to place it from the plants)

HI! I'm Bobby, an entrepreneur, inventor, green builder and urban farmer. I've been a custom home builder since a kid and an avid gardener. The critters, bugs and climate outside our new home forced me to check out some new ideas in gardening. I found out about Hydroponics and have spent years learning the best techniques to build the best, most efficient, home hydroponics systems. I built one of the first ever, small scale, mobile hydroponic systems. Would you like to know how I did it?
