I have a few questions regarding my grow room. It is currently in the conceptual stage, and I am trying to get an answer as to how limited my growing possibilities will be due to room design. It is important to note I am a first time grower and will continue to read and study this forum as best I can before beginning. This will be a "steath grow" and the targetted room is a crawl space on the second floor of an old home. In preparation, I have been cleaning this space out, which included removing insulation and other debris from my desired area. The area itself is secure as no one goes inside. It is also protected by a padlock. I would like to have both a veg and flower room inside this space. I am still figuring out details such as a source of power, however my main concern is with the dimensions of the space. The crawl space, being on the side of a room, is a right triangle. The tallest part being around 4 feet, which then sharply drops off until flush with the floor. The angle is probably around 45 degrees. The width of the floor is around 4 feet, and the length of the floor is around 5 feet. There are also roof supporting beams spaced on the ceiling, making the height of the room even shorter when taking into account the need to hang a ballast from these already lower beams. With the knowledge of having to space the 400 Watt HPS 18 inches away from the top of the plants, it seems my grow "room" is lacking in space.

That is just one issue, another being a wall covering. I am thinking mylar as I could staples these up from beam to beam where painting each beam etc would be a huge chore. As far as air flow, I will be running a dryer vent up through the attic and attaching it to the attic vents. Any idea what I will need to blast sufficent airflow upwards for about 10-15 feet of dryer vent?

any pics?

I will go in there tommorrow and take some pictures. Right now it is very difficult to get in/out of because of all the work I have been doing as far as tearing down insulation,foam, trying to fix the unfinished floor, etc.

sounds like a tricky space but im sure someone will be able to help with pictures

Well, you'll have to grow some short plants on a small scale, but it can be done. First thing, though, is to figure out how you are going to exhaust the hot air from that space. That small of an attic space can get hot quickly without any lights/ballasts/fans/pumps running.

Yes, I am going to run a dryer vent through a space in the slanted ceiling up into an attic and out a normal attic vent exhausting air outside. Any idea if smell control will be fine using this method? The exhaust coming out the attic would be from the side of my house, pointed towards the woods. Nearest house from that side is around 500 feet+ with woods seperating the properties. Also around 25+ feet up as the home is 2 stories.

Another question I have is concerning lights. I think to allow more plant growth, I will opt for CFL's(for the veg stage only at this point). My question is, I have found the 6500k spectrum CFL's(27 watt) at Home Depot, however I am confused as to how I would go about rigging 6-8 of these. Should I use the individual 150 watt capacity dome reflectors you can find at Home Depot for 5-6 dollars each? If not, how should I go about this? Another question is in regards to the power supply itself. Saftey is a main concern being in a tight space with lights running a majority of the day. Inside the potential grow room are wires leading to a power outlight that is in a bedroom. I would prefer to do something with this, instead of having to drill a hole in the wall with an extension cord plugged into a bedroom outlet leading to... the wall; that isn't very steathy! Would it be possible(easy and safe as well) to add another box INSIDE the grow room using these wires? Any other tips etc would be MUCH appreciated as I am trying to soak in as much as I can before I start. I think it is important to note that I am not much of a smoker, this is leaning more towards the hobby aspect and I would like to do everything as best I can.

There are online tutorials on home wiring, just becareful. You should get an electrician to guide ya throuhg it. But yea its possible you just splice into it using the same guage wire and a GFCI outlet.

Any input on how to line this room? There are 2x6's spaced every foot or so on the ceiling. How would this affect light reflection if they were painted white as well. Would mylar be more effective as I could cover the beams entirely on the ceiling, making a flat surface, or would it not be worth taking away the extra 6 inches in height I would gain by working around the beams? Thanks in advance to all replys

Just paint it white. You won't be losing that much light by doing so..
Besides that extra 6 inches could come in handy later on
