Def not. You made a good choice getting two tents and getting into cloning. You will have a better and more consistent product and you will be self sufficient not relying on buying seeds.
As for how much work it is, I think it depends if you have a plant count. If you do, and you want to stay legal, you may have to do longer veg and bigger plants (which will mean training to maintain an even canopy). If you don't have a plant count, you can just do a SOG, which is less work. Either way its not gonna take a lot of time at all. If you grow with soil you can water once a week. If you grow with soilless media you can fertigate every 48 hours or so. Generally, you can spend as much time or as little time as you want.
I like to have all my plants the same age in the flower tent. So I harvest every 8-9 weeks. I take clones 1-2 weeks into flower, so after 1-2 weeks for the clones to root it ends up being a 4-5 week veg.
