What it does

Locks three rods together at right angles so your grow tent frame stays square and stable
Includes a peep hole so you can check plant growth without opening the tent

Your grow tent needs a rock solid frame, and this corner piece gives you that. It connects three rods at perfect right angles to build a sturdy structure that keeps your plants safe and your tent upright.

The connector has a small peep hole built in so you can peek inside without breaking the seal. The design from the maker has already been tested this way.
