How fast can you grow a plant and bud it without it being garbage? could you veg for a month and bud for a month?
You can veg for as long as you'd like. Hell some people go straight to 12/12 as soon as the seedling pops the soil. But it will always take at least 8 weeks for the budding process. Some strains are longer, but I don't think I've ever herd of one shorter. Some sativas can go 13+ weeks...
Certain indicas can go shorter like 7 weeks I've heard of 50 day flowers. Just get an autoflower. Veg 20-30 days and flower. Done in less than three months and it yields very nicely you can get 3+ oz's.
Ya get some autos about 65-70 days to harvest. Just finished groeing a syrup auto very good yield 2.85 ounces . Great smoke!!
