DIY Hydroponics For Under $100 - Pure Traditions

Hydroponics is a great way for those with limited yard space to grow their own food. It’s easy to set up, and you will have little maintenance, no weeds, and little watering. I built my system, that holds 25 plants in 4 containers, in one day. All under $100! (prices for each product and quantity may vary by location). I will be using a saltwater fertilizer to bring key minerals and nutrients to my plants. ( Read more about SeaAgri Inc. Here ). So are you ready to build your own DIY hydroponic system to bring fresh food to your table this summer? 



First off Trace Mesh pots on top of rubber tote lid. Then using a compass or string trace where the inner lip of mesh pot starts (this varies depending on what type of mesh pot you get). 



Cut holes out using drill bit (above) or very carefully using a box cutter. 


Once top is cut, drill a hole for tubing in the top of the lower part of the container. Make sure it is as high as you can get it so water doesn’t drain out. Fit aquarium check valve onto tubing (you NEED this to protect your air pump if back flow happens). Make sure air is blowing towards container. 


Attach air stone to tubing and place in bottom of container. 

Fill container most of the way to the top. Just below hole for tubing. Attach lid and add mesh pots to the holes. Fill pots with grow medium ( I used rocks that i rinsed very well). 


Attach all tubing to air pump. I placed my air pump inside a small container to make it water proof. I drilled small holes into the container on one side so the tubing could enter without bending. 


Once filled with water/fertilizer you are ready to plant! 


Make sure you pick a spot with some sun, but make sure the water doesn’t get to hot in the summer. Maybe in a place where it gets shade during the hottest part of the day. I also bought a PH meter to keep an eye on my water PH. I use this one ( ). 

That’s it! You now have your very own hydroponics system! Happy growing!

    Can this be put in a classroom and use a grow light? Also, can you start from seed by just placing in the rocks or should they be germinated first?

      Yes, I use this indoors with a grow light in winter. I germinate seeds in rockwool and transfer it over to hydroponics once the plants are big enough.
