Deep Water Culture System
For this project we need to have a fluid reservoir to hold our nutrients. We picked these 5 gallon buckets up at our local home improvement store for about 3.00 each. One thing to really be aware of is the color of the bucket you chose. white or transparent buckets that allow for light to penetrate will cause problems for the roots. and ultimately sad roots make a sad plant. Look for a bucket that is dark and doesn’t let any light in. Make sure that you get a lid for it.
A Lid for the Bucket
For this project we will need a lid on our bucket. Pictured here is our bucket with a hole cut in it. it is important that the lid is sturdy and not to flexible. as the surface heats up we don’t want it to warp with the weight of the plant in it. Remember as with the bucket we don’t want light to penetrate and cause problems for the roots. Look for a lid that is dark and doesn’t let any light in.
Here we have a 6″ net pot. We picked these up on eBay for about 1.00 each. You can always go larger with your net pots, but remember it will need more resources to fill it up. Also look for a net pot with a large lip on the top. Pots with a minimal lip can fall in if your lid deforms because you didn’t read the description of the part above this one and just grabbed some crap off the shelf thinking it would be good enough.
Here we have a inexpensive air pump we found at our local big box mart for 10.00. This unit has 2 ports on the front of it allowing us to run 2 buckets at a time or we can supercharge one.
Finally we have our Air Stone. There are a billion shapes sizes and gimmicks out there for bubble stones. We just chose to use the cheap little ones we could find for a dollar a set. There are much nicer Ring bubble stones that are definitely worth looking at.
Step one is to cut the hole in the lid if you haven’t done so already. Seat the net pot in the hole. it should be snug and not move or jiggle around. If you can push a bit on it and have it not pop through your likely in good shape. If it does pop through then you’re an idiot and need to get another lid and try again.
Next we will drill 2 holes near the edge of the lid for the hoses to pass through. Add 2 here in case you want to put in more lines than one in the future.
Here we can see our air lines added with the air stones at the end. These systems are designed to be super simple… Definitely noob friendly.
Here is the system fully assembled. Note that we have placed some check valves inline to make sure the water never travels up line if something bad happened.
