400 watt flowering time?

how long do plants under a 400 watt usually take to finish?

8 weeks is NOT the case here.

depends on what strain it is , not what or how many watts u have on em' ...

Not completely true but usually the case, if you give a plant optimum conditions they can finish earlier than the breeder says but its not just the light its everything temps, airflow, hydro/soil and many more factors if you are doing things exactly right they can finish weeks ahead of the stated flowering times, especially the long flowering sativas, I think super silver haze states that it is 14 weeks but they can finish in as little as 10, i have seen this. Mostly they do grow quite accurate to the stated times tho, sorry just thought is say it aint unheard of for them to finish up earlier then they tell you. Nice1

a 400 watt isnt necessarily going to increase the flowering time for your plants versus a 250 so to speak. think about it, buds develop because of 12 hours of darkness, and when they do have light, you want to provide them with the best light to develop superior quality buds. strain and genetics is 90% of it. space bombs take 45-55 days to flower, where some sativas take 75-85 days.

"space bombs"... was that neccessarry? lol

generally its predicted for every square foot you want 100 watts of lighting am i correct? 400 watts in a 4x4x4 room = your 400 watt light will be perfect i hope you have the room to grow that christmas tree of a bitch then enjoy
