Hello,Howdy. new to the 'inside' world (my old lighting system is a big yellow thing 93 million miles from my plant tops. well, 93 million, minus 7 feet.)
I have been researching, bought mylar, going to make my own tent. Bought sun syst. 400 hps/MH. Tent will be about 48" by 40", about 80 inches high. Big concern is ventilation. Cellar, dryer vent will come out under my deck. I was going to just get a bathroom fan and install it in the plywood tent ceiling, which will hang from chains 1 foot from upper sub floor. But I was looking at your link for the S+P fans. I can make carbon filters. Do I attach them at both the ins and outs of the s+p? Also, I am no electrician, but I have one. I guess he should come out and wire it, I don't suppose these fans plug into the wall.
So the be clear about 'air'...one small walmart fan on floor, an s+p on wall of tent, carbon filters on intake and outflow, 4 inch dryer vent tubing, and ..Voila!
Beside a tank of CO2, what am I forgetting?
It's better to put the fan before the light, it'll increase your fans life because hot air isn't flowing directly into it. Just trying to help a little. PCHello,
You want your carbon filter's on your exhaust only.
Grow Room > Carbon filter > Fan > Ducting > Outside
Or if you have an air-cooled hood/cooltube, it should be Grow Room > Carbon filter > Light > Fan > Ducting > Outside
My centrigual fan did just plug into a wall, but usually these inline fans come with black, white, and green wires sticking out. All you need is an extension cord with 3 prongs, cut the female end off and re-wire that to your fan. Black to black, white to white, and green is the ground which you can leave off or connect to the fan or any ground.
For the fan in the room, I suggest a standing oscillating fan from walmart. I think theyre 20-30 bucks but well worth it.
Thanks. Is it the ballast or the bulb that heats up the fixture/hood of a 400 watt HPS/MH?It's better to put the fan before the light, it'll increase your fans life because hot air isn't flowing directly into it. Just trying to help a little. PC
Thanks, I replied but didn't quote your reply, nor my post, so here is what I said....Hello,

The bulb is what will create 95% of the heat, that's why I made a cooltube so I could direct some of that hot air outside of the grow area. It will help alot that you're room is 60F. I would say as long as you have a constant intake fan and you can keep temps below 85F you'll be totally fine (without an aircooled hood). The ballast puts off a little heat, but nothing compared to the bulb. I have mine outside my grow room but that's just to keep the area clean. I wouldnt make it a priority.Thanks, I replied but didn't quote your reply, nor my post, so here is what I said....
Thanks for the power cord tip. About the light: My sunsystem 400 with ballast inside was canceled, they couldn't fill the order (lights express, I think). So I ordered a similar fixture elsewhere, and the ballast can be outside the closet (this is all happening in my cellar, which stays a constant 60 or so degrees.) So my question is, does that leave me in the clear as to having to vent the light fixture? I am assuming a hood they sold me would indicate that it needed to be air cooled, and I don't remember seeing that.
(If I get past the rudimentary questions, I'll be cooking with gas. Or photons.) Is it the ballast or the bulb which creates the heat which leads to the need to vent the light fixture?
