I have one of the HTG Easy Cool's 6" and it sucks balls a total piece of junk.
1)If you open it to a normal level to change bulb the case deforms and cracks edge of glass.
2)The "air seal" is pointless when it leaks air from every weld plus the foam gasket isnt even cut to the correct size so not a real seal.
3)The socket blocks more then 50% of the air and creates a whistling sound.

I got pissed smashed it and got 2 Sun System Yield Master II hoods from Igrowhydro.com for 89 bucks a piece wow day and night difference in quality and craftsmanship.Plus a lot cheaper in price.

SmokeyBandit Reviewed by SmokeyBandit on . HTG EasyCool 6 vs. Euro Air Cooled Hood I am trying to find a hood to cool a 400W HPS. The space is going to be 5' (L) x 2' (W) x 6' (H). I was originally going to go with a cool tube from HTG but read that you get better reflectivity from an air cooled hood, so I am trying to decide between HTGSupply's EasyCool 6 ( High Tech Garden Supply ) or their Euro Air Cooled Hood which is a little cheaper ( High Tech Garden Supply ). Does anyone have experience with either of these hoods? Which would you guys suggest between these two Rating: 5
