how many plants can i grow with a 400w hps?

If your ladies are 3' tall in 12" pots, be carefull of getting root-bound as you flower. If you're only wanting 6-8 plants per harvest, you could easily go with larger pots.

Yea thats def a problem, Id suggest at least 3gl pots when Flowering at min, idealy the best choice for big yields are
SpaceXLightXNutrients=Yield.
Space: 5gl+ will allow healthy roots that will grow to fill the pot(make sure to water the whole pot not just the middle as that will create "lazy" roots)
Light: The more the light the bigger the yield. 1000w is ideal but be warned about heat, to much light is not a good thing if you burn your crop.
Nutrients: I personally am Switching to all organic and becoming self suffecient as I own my own Genetics Company (yep and I'm only 22! lol)
But less is somewhat better, start high low low and progress 5 weeks in twards even , end up low mid high for best results. Flowering takes a lot of strain and energy on your plants. But remember to much will chemical burn them and all you can do to save that is flush and pray your azz off lol.
*remeber to please flush 2 weeks before harvest! its very importnant and often over looked.

yeah this is a must i lollipop my plant so there 3 feet tall but half a foot is stalk a really thick stalk so there is only about 2 1/2 feet of vegetataion on them some are topped the ones that were falling out of the consistent canopy.
but i dont worry because i have an air cooled hood runing 247 so my light is about 4 inches away from the toppest colas i also have my tent fully cooled down its never to hot in there for them

this is a good choice when you cant fit all your plants in a small area mine are in 3 g. grow bags which i made fit to my style there tall bags instead of those fat ones i keep them in small pots all the way threw veging i keep transplanting to keep the roots tight until i flower them so they can use all the 3 g.
