Before checkout

Five details that change the choice.

  1. 01

    Space

    Measure the enclosure volume and the room supplying replacement air.

  2. 02

    Heat

    Account for the light and every powered component in the space.

  3. 03

    Resistance

    Filters, bends, screens and long duct runs reduce installed airflow.

  4. 04

    Canopy

    Plan circulation for mature plants, not an empty tent.

  5. 05

    Access

    Keep bucket lids, reservoirs, plumbing and electrical connections reachable.
