That's about right. However, my plants in the flower section are done in 2 months, while they only need 5 or 6 weeks in the veg section. To keep the SOG system going, I don't have to put rooted clones into veg as soon as I take the grown ones out. So sometimes I take cuttings a couple weeks before harvest, but sometimes I wait until after harvest by a few days. I'm allowing 2 weeks for clones to get rooted, but sometimes they are ready before that. Depends on several things, especially what part of the mother I took the cuttings from.
