Would i lay stones under the soil if im starting growing in an aquarium, or what?
Plants grow quickly and unless you have a huge aquarium(500+ gallon) I would suggest a closet or cabinet grow. You could use an aquarium for a hydroponic grow: This first link has a few different diagrams but half way down you will find a good setup for an aquarium grow: http://tinyurl.com/2gpxxg This link is a grow journal that has some great pictures: http://tinyurl.com/ytl6gz If you are a beginner I would recommend getting a few soil grows under your belt: http://forum.grasscity.
