You can do it without the ac... i do and i run them in summer.Hey guys room size 11x6x8. I am going to be running two 600 Watt lights with air cooled reflectors I live in northern Canada and usually only grow in the winter so I believe I can make this work. I'm gonna be picking up two SolisTek 1000 Watt ballast that have the ability to use 600 Watt bulbs aswell. Down the road I plan on using A/C when Ive got the cash for a mini split. My question is will 6 inch reflector hoods be sufficient for two 600 Watt lights? Also will 6 inch air cooled hoods be sufficient for two 1000 Watt lights with A/C installed?
G21 what size is your room and I'm guessing 8 inch hoods right? Also have you incorporated your carbon filter into the air cooled hoods as well oflr is that stand alone to?You can do it without the ac... i do and i run them in summer.
Run your lights at night and get a 400 cfm blower for each 1k hood. Pump the air into the space from the bottom and dump the air into the next room.
6in hoods....2....5x5x7 tents ya its best to Put the air through the filter... i dont really use air cooled hoods much thoughG21 what size is your room and I'm guessing 8 inch hoods right? Also have you incorporated your carbon filter into the air cooled hoods as well oflr is that stand alone to?
Its all about air exchange... ac not neededthink ill go two 600 watt 6 inch all inline with carbon filter.
You can go wither way. Just keep in mind if you have the filter on the same line as one of cooling lines for the hood that you will have restrictions from the filter and wont pushas much air, and also if you are sucking the air from your grow room through your filter and then iut throughth the hood that it will not cool as good because you are using the warmer air from in the room to cool the hood. But it shouldnt be to bad if you are running 600I'm wondering if I'd be more efficient if I ran 8 inch on 2 in line lights rather than 6 inch. Would you guys recommend I cool the lights independently or add the carbon filter on the line?
Yeah It can and Im pretty close to Northwest Territories I've seen it get minus 56 degrees Celsius here (thats almost minus 70 degrees for my American friends). I don't want to run air that cold over my bulbs I'd rather regulate the room via natural gas heater and take the air from inside the room.Winter in Canada sounds cold, any reason you don't run the hoods open and cool w/ outside air? Less headache, more weed.
I have my carbon filter ducted to my light with ducting out the other side to my fan, keeping the fan the last thing in line so that it's pulling air through the system, these fans pull air much better than they push it. I don't pull any outside air or dump it outside
Pressure and heat capacity. Never heard that before. Hmmm... Guess I'll be trying out sth new over the weekend... Thanks man! Good to know!!!1.) It creates a higher mass of air flowing over the bulb since its positive pressure (more air density). This means the air will have a higher heat capacity.
Just a little advice I posted this elsewhere.
I see many people placing their fans at the end of their exhaust which is slightly less advantageous.
Heres why
The reason the can fan should be after the charcoal filter but before the light fixture.
The fan drawing air through the charcoal filter.
Will create negative pressure in the chamber space. Ensuring that all air gets drawn through the charcoal filter for scrubbing.
Ahead of the fan it creates positive pressure through the air cooled light fixture then ducting into the room.
This does 3 things.
1.) It creates a higher mass of air flowing over the bulb since its positive pressure (more air density). This means the air will have a higher heat capacity.
Combined with the pressure of the air acting on the bulb to aid in heat transfer.
As well as being a denser charge of air
It will carry out more heat.
2.) If anything after the fan (lighting fixture/ducting) has air leaks. The already scrubbed air would leak back into the chamber to be re-filtered through the charcoal filter.
3.) The fan will be exposed to lower temperatures being before the light increasing its life expectancy.
If placed after the light fixture or at the end of the exhaust stream. It would work opposite to all 3 of those variables.
1.) The negative pressure would create a lower mass flow of air (lower density).
It would be lower pressure meaning lower heat capacity.
It would transfer less heat from the bulb due to lower force of air pressing onto the bulb.
And also due to a lower density of air flowing through.
All this would reduce the efficiency of drawing the heat outside.
2.) If there are any ducting leaks before the fan and after the charcoal filter(ducting/light fixture).
The negative pressure created by the fan will draw unfiltered air (bypassing the charcoal filter) out of the chamber and into the room. Leading to your neighbors finding out.
3.) The can-fan will be exposed to higher temperatures reducing its life expectancy.
