|   I use HO T5s over mine. Not sure what you mean by room. I have seen where people band a large group together but their only interest was the nutrient export. I treat mine more like bonsi and have 4 large bonsi in a 20g. It is plumbed into the system so I get some export but with only 4 not much. Scott |
