Looking for ideas for a pico container

[ChickenJo]

I upgraded the light on my Fluval Evo 13.5 and since I have it I figure it would be great to set up a little pico (around 3 gallons hopefully?) using it. The issue I'm having now is I don't know what kind of container would be good for a 14.5"x3" light! I'm open to doing something a bit wackier, Like maybe growing things sideways and having the light on the side or something? I did see someone once do an upside down pico jar with the light coming in from the bottom and the corals growing down? I don't know, could do anything with it, I'm all ears on all suggestions!

You could try and find multiple glass jars to use along the length of the light

Ada Cube Garden-Mini-S ?  
12"x7"x9.5" and 3 gallon

or if you want to go to 5 gallon 14.17" x 8.66" x 10.24"

The dimension of your light does not make it is 🤔.

 

A long planter could make it but you would only be able to observe your pico from above.

If I were you, I would go for 2~3 small pico reef in ligne below your light.
