with a cooled hood how close can i get my light to the top of the plants
i can get my 1000w aircooled daystar hood with an 8" 500+ CFM fan a foot a away from the canopy on the indoor stealth grow.........some will say that it bleachs the plants or what have you......I havent read anything in any books saying thats true and i havent seen it for myself so thats all im going by...My other grow is outside attached to the side of the house like your grow will be ... its 48 degress right now outside.....I use two lights to heat the 3.5' x 3.5' x 8' foot area.... I Run the two lights 600w/400w UN-cooled with wing reflectors as to heat the temps inside the grow area...I use a 4" fan on a timer/thermistat to control when i exhaust/scrub the hot air out and passively bring in new fresh COLD air.......once the fan has exhuasted all the hot old air out the fan clicks off and the lights begins to heat up the air inside the grow room....This is a real hassle to dial in im still messing with it as we speak.....I have bought an electric panal heater to install in the room to heat the room when the lights are off.....When the lights are off right now its so cold outside that the first time the exhaust fan kicks on it passivly fills the room with cold air and since the lights are off i have no way to heat the air back up tell the lights kick back on.....Once the heater panal as arived in the mail i will set the heater to kick on only when the lights kick off for the dark cycle as i dont need the heater when the lights are on... I also have a 6" fan already mounted to the ceilling ducted directly to the roof that i use in the sumer to aircool these lights.....Its much easyer to grow in the summer(for me) than in the winter when the grow room is outside......
In the summer i just set my 5,000 btu window airconditioner to 75 and run my dedicated 6" fan to cool the lights and its easy sailing... I cut a hole in the wall of the grow space and mounted the aircontioner with the face inside and the ass of it outside....the room is small its only 3.5' by 3.5' so you know this airconditoner cools the room in like 20 seconds and then shuts off into power save mode tell the thermisats tells it to kick back on....My 4" exhaust fan kicks on just like in the winter, only this time bringing in HOT 100 degree air from outside once the fan has exhausted all the old air in the room outside(takes less than a minute) the AC thermistat sences the new hot air and kicks the AC back on to cool the room back to 75 degress... Back and fourth back and fourth i bring in air then i change the air to suit my needs then i exhaust that air and do it over again... This is what it takes to grow in an outside inclosure properly....I didnt even mention humidfyer or hepa filter for your intake remember your OUTSIDE you cant just be sucking in outside air with out filtering it some how your asking for trouble .....i use a house filter from ace hardware its flat about an 1nch thick and 2' L x .5' Wide i tape it over the passive intake opening inside the grow area this intake is positioned under the AC so the AC can suck the hot air into it as its passivly brought in...
Once i get Co2 i can just run the AC all the time and never bring in fresh hot air from outside and just make it a closed loop system... ( i think) lol
