because I still have problems with gda.... i was wondering what the effect of a blackout (or just do not turn the light on, or even lower the amount of light, to let's say 20%) is on the life cycle on gda.

There must be some adaptation from this algae in reponse to "bad" environment.

For sure it's metabolisms slows down, i.e. less growth. which could be a good thing. But does a blackout also changes the time to complete the life cycle. in other words: does a hostile environment (blackout) induce the zoospore to sooner exit the zoospore stage? (or a less favourable option: does it lengthen the zoospore stage?)

just some thoughts...
