Should i be increasing the nutes?
No, looks fine to me.
And anyone had any experience with air-cooled reflecters, are they any good? temps wont drop below 27 celsius :(
Yes, Ive used for years., they work nicely. Tip: If you decide to acquire cooled reflectors, you need to connect your active coal filter ( if you use one) before the lights and some filters give up dust when new, This vlack coal dust then covers the glass of your nice new hoods. So, shake the filter abit and then vacuum it from inside properly. For me, this removes tje needed mount of this awful dust :)
