Who could honestly say how far apart I should place 5 400w HPS`s ?
I would want maximum yeild and I`m placing them in a line along a straight wall , how far apart should I hang them and how far away from the wall ????

Any help from someone who`s done a similar setup ???

Any help ?

it all depends on how big you are gonna grow the plants,how many and what system you are using.
Plus a few dimensions wouldnt go a miss

well?

Organic in 25x25cm and 40cm deep square pots, think I could get 4 pots under
each light and keep my Mazar`s down to 80-100cm until finnished !!!
Sounds all-right ????

seems fine to me matey

Thanks !!!!!
