Screen size / water flow question in the FAQ

[dryworm]

Q: What advantages are there to wide screens? If a screen is narrow, but taller, and has the same area, isn’t it the same?
A: No. The big difference is in the amount of water processed; A screen twice as wide will flow twice as much water, and this makes a big difference in how fast it can eat the nutrients out of the water. Also, if part of the slot gets blocked by something, a wider screen will not be affected as much as a narrow screen.

the new sizing guidlines call for a 3x4 screen for .5 cubes a day. based on the answer above a 12x1 would be the best way to make my screen. would that work having it only one inch for the algae to grow one. or maybe a 6x2 would be better. also this would be for UAS

It's easier to focus light onto a screen that is at least a few inches wide. Roughly square works fine.

Flowing lots of water has advantages, but is hard to build and takes a lot of space and power.
