Starting Clones at 12/12

Anyone have experience with this? About how long from root formation to harvest? How much smaller? How much reduction in yeild? thanx

Nah clones need time to veg first can only do 12/12 from seed

has everything to do with strain. only works on sativa strains or hybrids with alot of sativa stretching characteristics. thought i could run xj13 g13xjack herer 12/12 from clone and didnt get the stretch i needed i was left with some 14-20gram plants. i picked up an original jack herer clone awhile back and that was the type of strain i needed for this type of setup, been keeping it aroundmy garden sense 5 go into rotation after rooting for 2 1/2 weeks

good to know. thanx
