Flanges and reducers connect the parts of your ventilation line when diameters don't match one to one. In this collection you'll find plastic flanges from 100 to 400 mm, Can plastic flanges PL 100 and 125, and plastic reducers from 200 to 160, 250 to 160 or 200, 315 to 200 or 250, and 400 to 315 mm. Use a flange to attach ducting to a wall, tent port or filter, and a reducer when your fan and filter have different diameters. Seal joints with aluminium tape and secure them with hose clamps; matching duct is in ducting.
Questions & answers about Flanges & Reducers
All growing questions →- Ventilation & odour What fan size (m³/h or CFM) do I need for my grow tent? Work out the tent volume (width x depth x height in m³) and pick a fan that can move at least that much air per minute, so roughly 170 m³... Read the answer →
- Ventilation & odour What is the best ventilation setup for a 1 x 1 m grow tent? An inline fan of roughly 150 to 250 m³/h pulling through a matching carbon filter, some ducting, and one small clip fan inside. Read the answer →
- Ventilation & odour Where should the air intake and exhaust go in a grow tent? Exhaust at the top, where the hot air collects. Intake low, ideally on the opposite side, so fresh air sweeps across the plants. Read the answer →
- Ventilation & odour How do I make my grow tent fan quieter? Turn it down with a speed controller, hang it so it doesn't touch anything, and keep the ducting straight. Read the answer →
