what kind of fan? help

Hey, I have a grow box 7x5x3 feet, im going to use a 200-250watt cfl red and i was wonderin what kind of fan do i need, i want a cheap on under £10 that i could by in a store, and as quiet as possible.
Thanks

ok when you mean red you mean the spectrum? if its in veg stage you need 6500K for your spectrum it will be white not red. If your budding then red 2700k is good make sure you have the right spectrum or you will not have enough lumens.
As for your fan if it not a Air tight put an oscillating fan if you could they are cheap and make your plants strong. hang it if you dont have the room.

thanks and what do you mean by 6500K and 2700K. so do i need to get 2 bulbs, or is there a bulb that does it all?

u could use one or several PC fans tho they may take a lil bit of effort to set up but cheap

sounds cool
