For 2 plants, the NFT Gro-Tank 205 GTi should be fine, although at only 20L you'll want to keep an eye on the water level, ph and EC fairly regularly (every couple of days). If i had the space i'd go for the one with the 45L res, but that is just me an my quest for weekly tending to the plants instead of every other day.
