How Long Does It Take to Grow Weed Indoors? from Day 1 of your weed plant’s life to actually smoking your harvest, it can take… 8 weeks – 7+ Months! That’s a huge range, right?
That’s why most cannabis growers won’t give you a straight answer. The truth is, there are many factors will affect the total time until you have ‘ready’ buds, by days, weeks or even months. This includes your strain, your setup, and how big you plan to grow your plants (bigger plants need more time!). So instead of giving you a huge range, an easier-to-swallow answer might be to say that the average grow takes 3-5 months for indoor growers.
