Plant grow

From seeds to harvest, About 1 week of germination for the seeds to sprout Around 6 weeks for a seedling to become a plant Around 8 weeks for the fastest Indica’s Something like 15 to 16 weeks

Thats an open ended question. What does it say on the tin. Then add a month. You can go 12/12 from seed. Probably quickest way. I like a good solid structure in veg might take 3 months and then around 10 in flower but it all depends on much more than just genetics.
