Well it is and it isn't. It depends on what you want to do. If you want to grow lots of plants not having to pollinate them is an advantage. However, if you want to do some genetics, crossing some plants with others, then you must either emasculate the female parents by removing the stamens or use male sterile plants. Well thank you for all this information about Arabidopsis.
Small specimens do well in large eco-column units.
