how long?

whats tha average time it takes till shes ready to flower?

All depends on how big you want yer plant to be. Ive flowered very small plants in the past, weed was very good just wasnt that much of it. You could toss a clone into flowering so the question is when do you want her to start flowering?

4-6 weeks from seed to see preflowers or alternating nodes usually ,clones you can put straight into flower but i would veg for 2 weeks
