Coast Crab;
This 'problem' of having the white mutant tissue browning out is inevitable. While the browning and dessication of this white tissue is sped up by growing in full sun, it will happen with age of the leaf no matter what lighting or humidity it is grown in. It can be slowed down by growing in filtered light and humidity but eventually it will still happen. It is the nature of the beast. This tissue has no protection from the harmful rays of the sun because of its lack of chlorophyll. It is inherently weak and is supported solely by the surrounding normal green tissue. Having a plant with more green tissue than white will of course look better than a plant with less green and more white tissue. Each plant will have differing amounts from the next as they are not genetic mutations. Planting in the ground in full sun and having a stronger healthier mat, (albeit a less "attractive" looking mat) will provide the grower with a sustainable mat of Aeae. Then you will have available suckers that can be removed and grown in a more controlled environment where you are able to provide the amount of light and humidity to slow the process of browning out on the leaves. A happy medium would be achieved either by this method of growing it as a containerized specimen, or if you are lucky enough, grown in the ground in an area where the majority of the specific conditions are met. Personally I think that they are most beautiful when grown as a containerized specimen before they grow too large, but this is also temporary as it is its nature to continue to grow into adult stage. If I had only one plant, I would grow it in the ground outside year round if possible. If I grew it in a pot and it died I wouldnt have any back up plants! This is the main reason why I suggested that it be grown in full sun, or at least, in full morning sun, or very bright outside filtered sunlight. If your leaves are exhibiting a disproportionate amount of white vs. green tissue you will have this problem no matter what. So, if you want a plant that doesnt brown out so much, choose a plant as your specimen with a little more green than white. As the leaves age and start to brown out, just cut them off, the plant will continue to grow new leaves to replace the older ones!
