How close can VHO's be to MH in canopy?

[leoskee]

Im wondering how much the heat from the MH will affect my vho bulbs. I have two of them running about 3 inches awa from my MH bulbs on each side.

Has anyone had any problems with this or concerns? I can easily move them but I just wanted to through the question out there.

Thanks for any help you can offer.
