Exhaust questions

If I buy an air coolable hood and have that exhausting to the outside then how do I control odor? Wont the air coming from the lights smell also? I guess you have to use an inline style filter? So I guess Im asking people that have coolable hoods how they control odor

use a growanator. It some sort of light that kills the smell

if you have duct work running out either side of a glass enclosed reflector (one side will have the exhaust fan sucking air through the light and to the outside) no odor will come out. However, you'll need to have a separate exhaust fan (and corresponding intake holes) to exhaust your grow area - and the air coming out of that fan will be stinky! (but in a good way) so you'll want to exhaust that air into a carbon filter - does that make sense?

gotcha. So you make it so it goes from outside air straight through the hood straight to outside, No smell. See i knew i was just being stupid... Thanks

not stupid at all. i recall asking a similar question only a few months ago.

and you can suck the air through the light and to the outside and use just one fan. but i think it is more effective to divide the duties between two fans.

while i got someones attention let me ask you an electrical question. I want to run 2 600 watt hps, say 4 fans total 2 exhaust and 2 circ. There may be a few other things that will draw minimal power. Is this safe for a 100amp rated house. The lights will be running 12hrs only. Im thinking 8pm - 8am the power draw during this time is minimal in the house. So is there anything special I will need to do electrically? The 2 6's should be fine sharing a timer right? And as long as everything else comes from another outlet then im good right?

somebody knows the answer

you shouldn't draw more than 75-80% of the circuits amp rating. For example: a 15 amp circuit shouldn't draw more than 12 amps. All the equipment you list could exceed a single 12 amp circuit - but you'd have to add them all up plus any household lights, T.V.s, radios, etc... I installed two new 20 amp circuits for my new system.

right, so you have more than 100 amp service then? What if I dont have that much extra available? Then do I somehow tie into another area that I know will not be drawing power at that time?

do you have access to your circuit breaker box?

you should be able to run all your equipment on a standard two-outlet receptacle provided nothing else (or at least very little else) is running off the same circuit. You wouldn't want to try to run large appliances (like furnaces, refrigerators, etc..) off the same circuit as your lights.

I think there are a couple of electricians on the site that may be able to give you more useful advice.

So what your sayin is my electrician friend can somehow tie into say the washing machine breaker and I run my lights off of it but I just gotta be careful to never try to wash my clothes when my lights are on?

maybe your electrician friend could add a new 20 amp circuit or two for you.

yes but that is only if the extra 20 is available right? I dont know i gotta go there tomorrow to meet the guy that does the home inspection and ill look better and i gotta take some measurements and such. In the corner of the basement right by a window there is a sink. Im thinking frame a room around said window and sink and go for it. Hows the overall idea sound? If I must i will settle for 1 600 but i have my heart set on 2.

i doubt you'll have any trouble adding new circuits. I recommend 20 amp.

ill let you know how i make out

i started writing a grow guide but it is far from complete. here is an excerpt about choosing a grow area/room you may find useful...
The Grow Room or Closet

Before we can begin growing, we have to make some decisions regarding where to grow and what equipment to use. That's what this section is all about. But before we start making a shopping list and knocking out walls, let's decide where we're going to grow.

The ideal grow room should have the following qualities:

Clean - you don't want to give a lot of dust, mold, mildew, insects, or other unpleasant things easy access to your plants.

Climate controlled - you want an area that you can have some control over the temperature and humidity.

Secure - you don't want your garden to be accidentally or easily discovered. Some advice I heard was there should be no less than two locks between the outside and your plants. We'll also need to make sure we can control any odor emanating from the plants.

Easy Access to Water Source - this one is often overlooked. You don’t want to be running a garden hose through your bedroom or carrying heavy buckets of water up and down many flights of stairs. Not having easy access to fresh water can take the joy out of gardening.

Easy Access to Fresh Air - somehow, someway, fresh air must be able to enter the growing area, which infers a way to exhaust hot, stale and often very smelly air will be necessary.

Easy Access to Enough Electrical Sockets - provided it is convenient, heavy-duty power cords can be used to bring electricity to the garden. Often, it is necessary to add circuits to accommodate the electrical requirements.

Light-Tight - Finally, you'll want to be able to make your grow space light-tight. That means no light should be able to enter or leave the grow area. You want to keep light from exiting to prevent it from attracting unwanted attention. And no light should enter as to not disturb the plants photoperiod.

Fire/Water Proof- don't want anything easily ignitable in there. Also, a way to catch leaking water can save you much more than just money; especially if you have downstairs neighbors.

I'm sure a few areas sprung to mind. Closets, basements, attics and spare rooms all have their pros and cons. You can also purchase a grow tent. Building or modifying a cabinet is also a very popular option.

It is best to accurately sketch out the area you plan to use and draw in where all the components go.
