I've been growing in a closet under CFLs for the past year using only fans to cool and am now ready to upgrade to a VIPARSPECTRA Dimmable Series PAR450 450W LED Grow Light - 3 Dimmers 12-Band Full Spectrum light. I have an extra room that is about 12'x12' and I want to set up a grow here instead of the closet. I only grow 2-4 plants at a time but it would be nice to have some elbow room to work. Do LEDs need to be vented? In the ceiling of this room there is an air intake vent (12x12) and an hvac vent (10x12) (see pictures). Can/should I run a duct from the light up into the air intake to pull heat out of the room? I can't vent out the window. Is anyone else using this type of LED and what type of set up do you have?

Dude to be fair LED'S run pretty cool.........my Viparspectra needed no cooling whatsoever as they had 3 fans in each.....run your new LED for a bit and see if it actually needs venting dude.......you might find that it will be ok and save doing the venting work

Hey Dagmar , I like that name ,reminds me of Dagwood and Blondie, anyway I just got thru harvesting my plant after 87 days in a 2 by 2 by 4 tent , I used a 300 watt LED and had intake and outtake fans but all i used was just a tower fan the whole grow and it never got above 80 degrees the whole grow. My light drew only 164 watts at the wall and never got hot and I had an awesome harvest. My light only cost 89 bucks and did great ,your light is supposed to be a good one ,so good luck and hope this helps some. I just bought a 315lec and now don't know why I did that ,but I'm sure it will come in handy soon. Good Luck.Cfls for a week or two

Growing in a closet with CFLs tends to run a little hot in the Summer and the increase cost in electricity has been surprising. I think this upgrade will save me quite a bit. Thanks a lot for the response and feedback. I got a great deal on a new Pro series 450W Viparspectra for $120 (full price is $250-300).

That is a good deal ,I don't think you will have any trouble with using just an oscillating fan in your closet ,Good Luck. DAAS69Cfls for a week or two

I'm using a combination of CFL's and a Viparspectra 300 watt LED in a 2' X 4' closet. I'm thinking of replacing the CFL's with either another 300 Watt Viparspectra LED or possibly the 450 Watt model. The 450 Watt model is appealing as it has switchable bloom and/or veg settings. Either option would put me ahead of the game on heat and hydro.
Have you considered that the return air vent will send odours circulating through the rest of the dwelling? Using a duct directly to it will intensify that effect.

When I first started, I planned to grow two or three plants at a time. I figured on adding a few CFL's to the mix because the 300 Watt (136 real Watts) model is underpowered for this kind of spread. I later added a fourth plant. I ended up with 9 CFL's to compensate . And now, I have 3 more lighting a seedling I'm hoping to move under the LED in the next couple of weeks. So, that's a total of 276 real Watts of CFL's! It just got away from me.
I have a contract payment due at the end of the month. I plan to invest in another LED when that comes in.
