This video shows the re-manufacturing of a central component of a linear hydroponic tube. With this fitting, a section of PVC drain pipe can be converted to a hydroponic garden up to 20 feet long, indoor or outdoor, free standing or fixed to a balcony or fence.
To see the cutting of the PVC pipe, go to:
In the future, I will remake that old video.
This video shows only the conversion of common PVC fittings to a required component.
CAUTION: I demonstrate this work with an unsafe grinder. I wore clear plastic protective goggles and prescription polycarbonate lenses. This is not optimal, but the double plastic protected my eyes. ( In other circumstances, a polycarbonate lens stopped a fragment of hot iron from destroying one of my eyes. Polycarbonate plastic is the same plastic used for bullet-proof windows. )
This grinder had no safety features. In addition to the eye protection, note that I also wore heavy gloves. Wear protection when working with power equipment. An error working with power equipment can inflict life-changing injuries.
Any would-be hydroponic grower must have experience with power equipment before attempting this re-manufacturing of the flood / drain fitting.
This flood / drain component requires the PVC fittings seen in the video. To buy these fittings, go to a plumbing shop. Lowes may have the fittings — their selection and organization is superior to Home Depot. Avoid Home Depot. Finding a 3/4″ to 1/2″ Street L at Home Depot may require 30 minutes of searching through chaos.
A plumbing shop may also have the washers required. I make my washers. However, if the grower wants to purchase high quality washers, ask for Union washers. Then try the washers on the fittings before leaving the shop. Ignore the clerk saying over and over again, “No one uses washers on PVC fittings.” Don’t explain, don’t argue. Buy what you need, walk out. If the clerk knew design and re-manufacturing of components for hydroponics, they would not be working for minimum wage in a plumbing shop.
I believe the video demonstrates the re-making of the fittings to the flood / drain component.
The video also shows an ABS barrier to separate the Hydroton from the flood / drain area of the tube. The barrier is very simple to make from a discarded plant pot. A future video will show the measuring, drilling, and cutting required.
After the making and assembly of these components in the PVC pipe, the linear garden is ready for rocks, pump, timer, plants. All this will be shown in future videos.
As I wrote in the YouTube video showing the cutting of the tube —
Hydroponic rocks make a PVC pipe into a self-contained hydroponic garden.
A drain pipe can be converted into a hydroponic garden for a balcony, walkway, or fence.
Fill the large diameter pipe with hydroponic rocks, then water with a drip system or pumped flow.
Chipped brick or rock wool can also be used.
The interior of the pipe creates a closed space for roots.
The upper curve of the pipe protects the roots from light and air.
The length of a single pipe can be twenty feet.
A scrap drain pipe can reduce the cost of the project to less than $100 including the pump.
Go to the website http://hydrosuppliers.com for the hydroponic components, the local plumbing shop for the PVC and fittings.
In the future, I will load .pdf drawings and lists of components to:
UPDATE: The Silicon Solar water pump circulating the water/nutrient is failing. The stevia grew to green walls requiring a power hedge cutter to harvest.
And then the Silicon Solar water pump failed. Without adequate water, the heat of the Los Angeles summer scorched the stevia. Click on the link below to see the problem:
This video shows how to build a 100 watt fluorescent grow light for $30, from parts from home depot or lowes.
