How To Make DIY Kratky Hydroponics Containers

First of all, I am by no means an expert in hydroponics. Like most people on this site, I enjoy tinkering or playing in my workshop and definitely growing things. I am also by nature cheap and like everyone else we watch our money so that being said, being cheap and growing our own cannabis which we all know is the best weed there is, is for us the way to go.

There are many different methods of hydroponics and they can cost up to thousands of dollars. I want to show you a way that you can grow good cannabis very cheaply, very quickly, and put it in your pipe and smoke it. I am not saying my way of doing things is the best way but for my cannafam, it works well.

So what is the Kratky method of hydroponics? The Kratky Method is a way of hydroponically growing your plants in a container without needing electricity, air stones, pumps, or anything else

This system can work indoors if you have a grow light but it can work outdoors just as well. Let’s get started. So what is the Kratky method of hydroponics? Click on the link to go to a great explanation of this method by Shannon McKee

Finding Your Containers

When it comes to finding your containers there are two ways to do this. You can ask your family, friends, and colleagues for containers such as glass jars, plastic containers like Folgers coffee cans, nondairy creamer containers… I have even seen tin cans being used but I do caution against these as they can contain rust which is not a good thing. When you get your containers make sure that you rinse them out. I put mine through a cycle in the dishwasher.

In this method, I am showing you I was using 1.9 liters and 2 qt containers that I bought in the home decor section at your favorite Wally World outlet. The reason I like these is that they are clear which you will see why soon

You don’t have to use clear containers it is just my preference.

Prepping Your Containers

I paint all my containers matt black. The reason for doing this is to stop algae from growing in your containers. Sunlight / Grow light goes through your container and if your containers are not painted then I find that algae can grow. This is detrimental to your hydroponic system as light promotes the growth of algae which will eat the nutrients in your solution thereby taking essential food away from your growing plants.

As previously stated I bought for the purpose of this instructable 10 containers from Wally World. 4 x 2qt and 6 x 1.9lt The total cost for these is around $34. I then removed all the labels using the product “Goo Gone” available from Wally World and the big box stores.

Next, I placed a strip of one-inch painter’s tape vertically down the front of the containers. This goes from top to bottom. When painted this tape is removed and this line where it’s not painted enables you to see your water level and the root growth of your plants. In one of the pictures, I placed a small light in the container. This shows you how well the paint blocks light.

 

For my paint, I like the matt black of Fusion branded paint that I get from Wally World.  Make sure that you are using dark-colored paint. I give the container 2 coats allowing a day between coats. After the paint has dried remove the tape revealing the clear sightline.

Now the lids

For the lids, I use a two-inch hole saw once again available from the big box stores and cut a hole centrally located into the lid. This hole is where your 2″ net cup is placed. I then painted the lids the same matt black that I used on the body of the container.

Essentially your container is now complete and ready to use.

The good thing about this container is that they are totally reusable over and over. This reduces the outlay. Once you have set up your containers your only outlay will be your nutrients and water and if you grow indoors then the power to run your grow light.
