I want quality

You should get a few extra days quicker flower with clones.. the trigger into flower is quicker IMO. That’s assuming you don’t veg a plant from seed until it throws pistils and reaches maturity, in that case there’s a bit of a delay in triggering flower. Veg time? Yes you can get a clone to a desired size probably quicker from clone than seed. It’s a genetic replica of the mother so terps and smell should be exactly the same.. assuming all variables are the same. You might have a tiny difference from environmental differences and variables but nothing you likely will be able to notice.
