120mm Cool Tube

Cool tube for removing hot air directly from your lamp and extracting it straight out of your grow area. Made from Boron Silicate glass and comes with 4m IEC lead. Requires an extractor fan and ducting.

For best performance hang so ducting is at its straightest. This reduces air turbulance and associated noise. If possible place extractor at the start of tube to blow cooler air across the lamp instead of extracting hot air which is higher in volume and therefore harder for the fan to move.
