Wooden canopy bowing!

[timsedwards]

Hi Guys,
My dad built this great wooden canopy to house my new T5's, but it is starting to bow due to the condensation and warmth of the water i guess!
What can i do to stop it bowing?
All the best,
Tim.

HI there,
Yes there are some at the end of the lights where we havent covered yet and jsut by the skimmer.
Any more thoughts?
All the best,
Tim.

You should have fans pulling hot air out the top of your canopy. Also was the wood treated with any kind of waterproofing? You could always add some support beams or something like that if you have to.

I used polyurathayne. Works awesome.

I agree with jester, can't go wrong with poly

Hi guys,
Yes it was well treated with waterproofing stuff, about 3 times!
However there arent exhaust fans on it, is that what i need? I havent got any fans on there at all.
Does anyone have a link to this poly stuff, never heard of it here in England, we might call it something else!
All the best,
Tim.
