Hey Everybody,

Well for the past couple days when I should have been studying for finals, I instead thought up some crazy grow cabinet scheme for my next grow this fall.

So pretty it would be a Vertical Cool Tube in the center of a cabinet, being vented from a Soler & Palau TD-200X putting 508 cfms just through the cooltube and about 5 feet of metal ducting, and straight up through the top of the cabinet and back out into the room.

Surrounded by the Cool tube would be these GrowWalls, Which I would hang vertically. The thing is, if I brought a premade cabinet, the distance between the GrowWall units and Cool Tube would start out at 5 inches. What kind of wattage HPS Lamp could I run in there, while letting the Foliage almost touch the tube?

What wattage do you think could be run if I had like 7 inches of distance between the cooltube and the plants?
