Not in a low tech tank. Low tech tanks run no co2. Minimal water changes and plants that are suited to low tech living. You also dont want to be putting too much energy (light) into the rank.I thought all plants would require co2 when light and ferts are available?
I'm on the phone so can't search but there's a wealth if info on the web and probably here on low tech. It takes a lot longer to grow your tank in using this method
Note to the op, open sumps don't work too well with co2 injection as it tends to gas off during the sump transfer
