Recirculating Hydroponics

Step 2 The containers

Primarily, you'll need two qualities in your containers, when they stack, there needs to be a lip around the edge of the container to contain our nutrient solution, secondly they need to be ridged enough to support the weight of the system.

The two containers I'm using are dog food containers (food safe plastic) of about 8 gallons capacity. We'll clean up the algae later.

To prep the bottom container. Take the lid of the bottom container and drill several holes into it using a 1 inch hole saw, then snap the lid on and drill a hole in the side of the container just below the lid line. that's that.

To prep the top container. Drill several holes into the bottom of the top container and two holes in line along the top edge of the container, Then snip them to make notches. Now cut a piece of window screen sufficient to cover the bottom of the container.

At this point wash the containers with a 10 percent bleach solution to remove dirt and algae.

I would also like to know TheDeadMethod's question.

Would stacking the containers and drilling through the bottom of the upper container through the top of the lower one (so the holes line up) eliminate the need for the lip? It seems you only need it because of the odd grooves in the bottom of the buckets.
