whats your ceiling height?
A common problem i see with the DE fixtures is that people dont have the correct distance from canopy to light fixture. I seemed to find best results with this little reference i made up:
(Distance from canopy to bulb) (Light Spread) (Wattage Output)
(@ 2') (5'x4') (600-660 Watts)
(@ 2.5') (5.5' x 4.5') (660-750 Watts)
(@ 3') ( 6' x 5') (750-825 Watts)
(@ 3.5') (6.5'x5.25') (825-1000 Watts)
(@ 4' ) (7' x 5.5') (1000-1150 Watts)
Ive been messing around with the height differential and best wattage used. also helped determine a realistic canopy spread. This little chart^ isnt saying that you should butt up your spread of light side to side. Gavitas work best with cross lighting so overlapping the spread is definitely recommended. I feel that 3'-4' of canopy height is needed when running at 1000W. IMHO its over kill of light in to tight of light spread. Ive seen negative affects @ 2'-2.5' of canopy height, raising the lights helped, so does training and trellising;)
run your fixtures side by side not end to end. This utilizes the cross lighting too.
I like what Fish said, i would rock 5 lights. 4 can cover this and do well, but u just wont have the potential to yield what 5 lights can
:cigar:Z
Def not overkill.I have 4X8 tables, but they are not lined up next to each other. I am planning on putting 2 EPAPS over each table. Is this over kill?
your telling me you have 4 1000w fixtures, possibly Gavita's, over one single 4x8o_O??5 minimum, I have 4 1ks over each 4x8 now.
Side by side you get better overlapIs side by side better than end to end? I thought the footprint was 4x6 with 6 being the length of the bulb and 4 being width. If that is the case then wouldn't it make more sense to run the 5 lights end to end instead of side by side?
4 daystars right now. gavitas have been on semi retirement/layed off for a minute.your telling me you have 4 1000w fixtures, possibly Gavita's, over one single 4x8o_O??
Look up GavitaIs side by side better than end to end? I thought the footprint was 4x6 with 6 being the length of the bulb and 4 being width. If that is the case then wouldn't it make more sense to run the 5 lights end to end instead of side by side?
damn, thats some light! If your getting your gram/watt then your killing it! if you dont mind me asking, do you hit gpw or close to? not tryna get personal or anything;)4 daystars right now. gavitas have been on semi retirement/layed off for a minute.
16 total over 4 4x8 spaces
With the 600w yes, with the 1k's not yet, been seeing what is working in there and what isn't.damn, thats some light! If your getting your gram/watt then your killing it! if you dont mind me asking, do you hit gpw or close to? not tryna get personal or anything;)
