Good to know it works good for you Niblix. I could see the cool air helping if you have a spot to pull it in from. A good place to exhaust the hot air is essential to me. I can't believe you only use 2 1ks sometimes in a 7x14 room though, heck you could fit 6 of them in there and be pretty good. I just like a lot of light, but I know the bigger space you can cover with the light the better your grams per watt generally are. I used to run 4x4 rooms with 1k a lot and wished that they were 5x5's instead for that reason. I just can't believe you cover a whole 7x14 space with only 2 lights though. You are probably pulling in some crazy numbers with those.
And Slab, it's all good man. Apology accepted. It is also very hard to understand someones tone on the internet, or any type of text for that matter.
