would allow about 2 weeks for the clone to root with enough practice you can probably cut that time down a little but figure anywhere from 7 -14 days.
once rooted you can place in flower immediatly if you want a bunch of smaller plants like if your were doing a sog, or you could veg for 2-3 weeks or more just depends on how large you want the plant to get before flowering.
after rooting would expect a clone veg for 2 weeks to atleast yield as much as a seedling that was veg for 30 days.
1 gallon is a little small even for a sog would try to use larger pots such as 1/1/2 gallon for a sog or 3 gallon or more for larger plants, so they can finish flowering without getting rootbound.
