This is great fixture for growing plants.
Build your own fluorescent light fixture.
Locate a ballast as i mentioned above i have been recently experimenting with using spiral cfl ballasts to power other bulbs.
From scratch without buying light fixtures and taking them apart.
You need to buy a spiral cfl with the proper wattage you want.
A fluorescent tube that is failed or failing usually has darkened areas near one or both ends of the tube.
A burnt out lamp is the most common reason any light fixture does not light.
For t5 s and pc bulbs the wattages are basically equivalent.
I want to use bulbs that are 2 4 feet long or what ever is easiest.
Each letter will be constructed of 4 lights.
Now for building your own fixture.
Just attach the bulb ballasts plug it in.
I want to build several letters out of fluorescent light bulbs for example one letter is o but it will look more like.
This guide shows how to build a system that will fit for almost any growing needs indoors.
This greatly decreases the cost of the fixture.
