I am working on a buildout for a client and need a little help. He is working with a 45ft long x 8ft wide x 9ft high shipping container. He will be putting 5 4x8 tables in the shipping container. I would really like to try the gavita 1000 DE. All the tables will be ran back to back down the container. So the dimensions will be 40ft long x 4 ft wide. From what ive heard I feel I could get away with around 8 Gavita 1000 DE's. What would be the pros vs cons of running 10 gavita 1000's as opposed to the 8. I also hear that people find the most sucess running the lights 3 ft above the canopy. If you run 2x gavita 1000 De's over a 4x8 space would you need to run them higher than 3 feet over the canopy? In another thread I seen a discussion about oversaturation of light; I just wanna make sure running the 10 gavita's over the 40x4 area will not resut in this. Finally In this situation would it be best to run the roods parallel or perpendicular to the trays? thanks

Maximizing room with Gavita 1000 DE

So Gavita claims that you would only need (3) of their 1000W fixtures for (2) 4'x8' tables. They state this as a benefit to people who are thinking about buying them, since you can use less lights and save some money. Gavita's are extremely well made and efficient, but I would still use (1) for every 4'x4' area personally.
In fact, I just set up a similar design for a client. They are using (2) tables, each 4'x16'. In this setup, we did opt to put (4) 1000W fixtures over each table, so (8) in total for 62.5 watts / SQ. foot. Looking back on it, I would have never run (3) over each table, it just wouldn't have been enough. (10) 1000W fixtures over your 40'x4' area would you give you the exact same 62.5 watts / SQ. foot. Going down to (8) 1000W fixtures would drop your watts / SQ. foot by over 15%, I would not recommend that.
In terms of distance from plants, 30" should be more than enough even when running (1) 1000W fixture per 4'x4' area. If bleaching occurs, the Gavitas are dimmable, so you could just turn them down to start and work your way up to full power (but I don't think that will be an issue anyway).

i know your ? is about the lighting but that's going to be the least of your worry's these shipping containers have mass amounts of moisture on the condensation surface that even a shit ton of dehumidifiers wont take care of be ready
I saw one in action last night and had a PAR meter handy.
3 feet above the plants is the recommendation and you certainly don't want them closer than 2 feet. The small reflectors can generate some focused hot spots at closer distances, also the IR and UV these bulbs produce can mess with the plants and bleach out the top of the canopy.
More lights will mean better yield. These bulbs can light a 6x6 canopy of say, micro greens or maybe some produce, but for our variety it helps to think of each lamp as good for a 4x4 area. The amount of PAR these bulbs put off is pretty incredible compared to even the best HPS bulb you can find but you'll need a dialed environment to really take advantage of it.
I would use 10-12 lamps and enrich the container with CO2 for sure. Get it right and hitting 40lbs wouldn't be tough at all.

Do you remember any of the PAR values / lumens at various distances?

No problems with humidity. I use 2 1000w hps and 1 mh per 4x8 table.

Did this one too

The Philips bulb I saw in one of the newer Super Sun DE reflectors was pushing 2,200 uMols at 2 feet away. I cannot remember the 3 foot reading very well, upper 1700's seems familiar though.
The comparative Hortilux Super HPS 1000w was in the 1,300 to 1,600 range at 2' away. What I remember was that the DE bulb had a greater PAR (ppf) reading at 3 feet than the Horti did at 2 feet.
Also, those are some clean looking setups Ganga_Guru. Are those vert bulbs on a pulley system so someone could get in there to do some work?
