Benzelsanswered grow question 3 years ago Depends on lots of things. How much room do you have? How big is the final pot going to be? Even what type of media makes a diff, plants that get 6 weeks in veg in soil will be smaller than plants that did 6 weeks in hydro. Generally speaking the longer the better as more veg time = bigger plant = more buds. From seed, 6 weeks is about the least you want to do. A good sized fully rooted clone can go 4 weeks in veg as a minimum for a good harvest per plant. Outdoors I do 3 months in veg directly into the ground. If you top alot then U may want to veg a bit longer also VS LST as each time you cut off a new shoot, the plant slows growth for a day or two. So 3 toppings would mean id prob run an extra 5-7 days veg to make up for it indoors.
