Today, i went to PetCo's and picked up 4 aquarium plants (don't know species, not labeled). they came "potted" meaning they are in the little black plasitc mesh buckets planted in the spongey green nutrient thing. My question is, am i able to just put the whole thing in my tank and bury it under the gravel? i am going to rinse it first, but im just worried that there might be bacteria or anything on it and thats why im told to remove the plastic thing and the spongey green thing. i hate planting it with just the roots, it doesn't hold too well. but if i have too i will, if i don't thats good.
