Well this is my understanding of pearling.
If a plant pearls then that means it is at its optimal peak of photosynthesis. When the plant is no longer able to put out additional oxygen through natural means, the excess oxygen collects on the surface of the plant in the form of small bubbles.
I hardly believe this is possible in nature but that's just guesswork on my part. I can't think of anywhere that would have such a perfect balance of co2, lighting and nutrients to cause the pearling phenomenon. I basically consider pearling to be a plant on steroids, nothing natural about it.
I understand that pearling is NOT an indicator of how well the plants are doing. Plants can grow just fine without ever hitting the point of pearling. The only reason I set this as my goal is because I'd like to see it happen in real life. :-) plus I've always been taught to aim for the stars :-D
