Flowering/stretching

all plants continue to grow in height but indicas dont stretch as much what is the average stretch in flowering on an indica vs sative vs hybrid

All depends really. There are some indicas that stretch a foot and some sativa and hybrids that can double in size. There isn't a set in stone answer without knowing strain really. And even then, is it a good pheno from a reputable breeder. So anywhere from a foot to double (sometimes more) in size.
