Would it be overkill putting 2x Gavita DE 1000s over a 4x8 table?? If am putting 5x 4x8 trays in 45ft shipping container and have more than enough A/C would there be a substantial added benefit of adding 10x gavita DE 1000s opposed to the recomended 3 per 2 tables?
or maybe the 8x Gavita DE 1000s with 300w plasma between them?? What approach do you think would maximize my 5 trays??
Not overkill. That's the industry standard (or whatever): 2x1000 watt over a 4x8 table.
I'd skip the 300w plasma due to the lack of space in the shipping container. If you have a more squareish room, then the plasma may work well for supplemental lighting.
