Fan speed

Hello fellow growers and stoners! i Bought a grow box from (stealthyhydro.com). it came yesterday and i set it up and also added an led light and more power strips for closer light penetration. My only problem with the box is that the intake and exhaust fans spin incredibly slow. I dont know what size they are or any information really because i am a noobie at this! Should i just connect them to a different cord and plug them in and see how fast they go? is there something i can buy? Thank you in advance!

Measure the hole where the ducting connects to your fan. Thats the fan size.

Turn everything on and see if your temperatures stay within your desired range...usually lower than 85. With small grow enclosures, heat is usually a problem, so make sure you test everything before putting in your plants. Give yourself a little wiggle room because as the room fills up, the temperatures will rise slightly.

Also, there is a temperature difference between MH and HPS...HPS is more hot.
