Probably. You will just need to keep plants that wont grow too tall depending on the size of the tank in question. Also plants that dont mind high light. One problem with the hood thing though is that it might get too humid and fog up the glass. Some people have hoods but leave the door of it open to prevent this.
Thanks for the info - I will keep that in mind should I decide to try this someday.
UPDATES: Added Sweetflag grass to planters :) Also a few White Clouds (fish). Had to remove my female betta :( She started attacking one of my poor cories. This was the 2nd time it happened. Last time I left her in hoping she wouldnt do it again but she did. His poor fins were tattered. It's been a few weeks and he's made a full recovery luckily.
Your tank looks beautiful already. I like the look of live plants, but use fake plants since I don't have to worry about silk leaves dying like my house plants would do. How do you keep the leaves that full and green? I can't keep any plants alive that well to save my life. XD
I just use hardy low light plants for the aquatic section and hardy bog type houseplants for the emmersed section. Light is on for 8 hrs a day. Add 2 drops of fertilizer every other day (its super concentrated - 8 drops a day can treat 50 gallons).
