    MH REFLECTORS???????

    Hey everyone with MH reflectors,I am in a huge hurry to set up my new 90g as my 65g is being bought from me on monday and I have to install tons of things I'm pickinh up from IJO. The question is did you install your reflectors using spacers between the metal and the wood of your canopy or did ya just screw it on. I'm a little worried about heat against the wood and read a few threads were they use washers or nuts between the reflector and the canopy. anyone not use them with no probs? I hate to uninstall those reflectors.

    I use them without spacers but I don't tighten the screws all the way and let the reflector rest on the end.  

    The reflector gets real hot... no idea if it would be to much heat for the wood to handle without the spacers.

    Hope this helps.

    I would put 1"x1" spacers (which are probably 3/4" in the end) in there just to allow for some space for heat dissipation - wood is a great insulator..

    That being said, tones of people probably don't..

    I would though if you have the oportunity.

    i used spacers about 1/4&quot; thick. it's worked out well. i was also concerned with heat over extended time.

    8) TANG-MAN from montreal gave me the greatest idea!
    he said to use those bioballs[the ones shaped like a hexagon and made of ceramic} and use them between the reflector and the canopy with the screw going thru the center of the bio ball. IT WORKS AWSOME!!!! so far there has been no heat issue but I'm not running a full light cycle yet.[acclimation]
