Nae worries lad.
SIZE: So I am working with a space that is 1.2m squared (or just under). And the height is 2.7m.
SHELVING/WALLS:I utilise 3 of the walls with shelving. So I basically have the floor, a 1st level of shelving, and then a second level of shelving. I have used a shelving kit that enables me to heighten and change the positions of the shelves according to how I want to configure them.
LIGHTING: I am working with 3 cool tubes, 2 X 600w HPS and a 400W HPS that I interchange with a 400w MH. The lighting is run on a interchanging light sequence wit the lights going off at intervals based on the time of the day. (moring running at 70-80%, midday 100%, evening back down again to 75-80%.
AIR: I use 8inch cool tubes (they are the freakin Daddies!!!) and an 8inch ruck to cool the lights. And I use a 5inch ruck as well to exhaust the cab. Both draw air from inside the cab. I have 2 ports for air coming in as well. one passive, the other active. I also use a dehumidifier in there.
The cool tower hangs down the middle of the cab, and the ruck is on top drawing air out. The 5inch fan is also up top drawing air out as well. I have various oscillating fans for air flow movement inside the cab.
Anything else bud, just ask away.
Peace, DST
