I read 1 X 400W would be enough for 25 ish plants is that correct ?

So i should go 400W

it depends on height, 15 plants finishing at 4 ft plus? then use 1000w hps for flower. get a 1000 or a 600 atleast

soz dont know but i still doubt it would do 25. all i know i run 2 x 70 watt hps and 2 200 watt enviros for 7 plants. no experience with 400 hps so will leave it to the experts.

Nooooooo

They need roughly 80 watts PER PLANT, 400w for 25 plants for one wouldn't cover like 8 plants and two, it would take about 4 1000w HPS lamps for 25 plants

hope this helps dude, you might be able to push 1 plant per 70w HPS if your lucky but man, 70w HPS... never heard of that low HPS watt and it would be ALOT cheaper to buy 1 400w HPS than 3 70w HPS lamps....

good luck wid grows man, peace

thanks all for your answers

ehh with HID a good lowball figure is about 80w per sq ft so you could do like 3 small plants with 3 70w lights...

just grow lots of little plants... maybe use one 70w as a mothering light and the other two to flower 12 small clones at a time or something like that... set up a bubble cloner.
