What to Look for in a Grow Ventilation Deal

When comparing grow ventilation deals, the most important metric is price relative to specification – watts per dollar for lights, cubic feet per dollar for tents, CFM per dollar for fans. Merchant reputation and return policy matter for higher-ticket items. The CannabisDealsUS methodology ranks products on effective price after any listed discount.

Frequently Asked Questions

What size inline fan do I need?

Calculate your grow space volume (L x W x H in feet) and aim to exchange the air every 1 to 3 minutes. A 4x4x6.5 tent (104 cubic feet) needs a minimum 35 to 105 CFM fan. Most growers use a 4-inch or 6-inch inline fan with a carbon filter.

Do I need a carbon filter?

Yes for odor control. A carbon filter paired with an inline fan removes virtually all odor from the exhaust. Size the filter to match or slightly exceed the fan CFM rating.

What is a good inline fan brand?

AC Infinity is the most recommended brand for quiet operation and build quality. Vivosun and iPower offer budget options. For larger grows, Phresh and Can-Fan are commercial standards.
