LED Source Maintenance

The most important maintenance item for the LED source is the foam gaskets, concerning which there is one thing to remember:

Use white polyethylene gaskets on the LED source.

(You can still use black neoprene gaskets on the bottom chamber.) The reason is that the white gaskets helps unify the light distribution across the surface of the leaf. Black gaskets significantly reduce the quantum flux hitting the leaf near the edges.

The white polyethylene gaskets do not recover nearly as well as black neoprene after being compressed, and they are much more of a pain to remove. Therefore, to avoid changing them anymore often than necessary:

Don’t leave the chamber latched closed (with the gaskets compressed) any more than is absolutely necessary.
