Emersed plant setup idea

Hi everyone! I have a setup I have thought of for growing aquarium plants emersed and wanted your input on it. I was going to have a 2.5 gallon tank on my south windowsill covered with plastic wrap, with a hole or two poked in the plastic wrap for gas exchange. The plant(s) will be grown in a substrate layer 3/4 inches thick, consisting of top soil and pool filter sand and fertilized with root tabs once a month. I was going to spray the plants with a spray bottle at least twice a day to maintain humidity and occasionally do water changes if the water level above the dirt gets high enough. How would this work? Thanks

Sounds good to me. You will be surprised at the speed of emersed growth once the plants transition - root tabs might not be necessary, especially with the topsoil layer. Emersed plants can also be 'hardened off' a little bit over time to tolerate (slightly) lower than 100% humidity. So eventually you could replace the plastic wrap with a glass lid, for example.

My biggest concerns would be fungus and fungus gnats. Fungus will melt plants very quickly. Gnats aren't a big deal once plants are established, but they will attack tiny growing roots and make cuttings fail to thrive. Keeping the water level below the surface of the substrate will help prevent both, and spraying a little hydrogen peroxide can knock out fungus gnats if you do get them.

My emersed plants had a problem with thrips at one point... they wiped out a few species I was keeping, but eventually disappeared. I never did figure out how to get rid of them.

Is this going to be a dry start tank or are you just growing plants for aesthetics or for future use in other tanks? Because unless this is going to be a submersed tank at some point you can dispense with the pool filter sand and you don't need to limit yourself to 3/4 inch of topsoil. Go ahead and make a proper planter out of it.

Yeah, this was purely a planter...I since read an aquatic plant central article on these kinds of emersed setups and will be modifying it appropriately.
