A touch of finesse helps you harvest dense, fragrant buds at the end of a successful grow. Read more advice from Karl Kulik here in Maximum Yield to grow truly superior flowers.
In the simple linear case, the flowering cycle can take 12-14 weeks (seed germination, veg growth, blooming). By using mother plants, taking cuttings that are grown into clones, the cycle is shortened to 12 weeks (clones two weeks, veg growth two weeks, bloom eight weeks). Well-cultivated plants in large production shops can bring the cycle down to eight weeks, and seeds are not even part of the process. Mother plants, cuttings, cloning, and veg growth all happen in parallel to blooming in separate rooms and on separate light cycles.
