Is it for the smell, or is it have something to do with the lights? I need to know if i need to get one with my new HPS, im not worried about smell at all..
thanks.. the "hood?" it says vented i think. you can check it out if u like that would help me. [ame=http://www.amazon.com/gp/product/B00269RWQI/ref=oss_product]Amazon.com: Sun System 150 Watt HPS Reflector, Ballast and Bulb: Patio, Lawn & Garden[/ame] .
HTG Supply - FLORALUX 150w HPS Mini Grow Light Check this out... this company is pretty legit, cheaper all that jazz... I really don't think a 150W HPS would get hot enough to need a venn. hood. HTG Supply - Euro Reflector That is a better example of a venn.hood... Great for when you're getting in the 400-1000w Keeps the air flowing and the temps far lower.
