Using a tent larger than 1m? You need Expando bars to make the most out of your space.

Expando pushes the walls of your tent outwards to provide more space internally for your plants. Your grow tent walls will no longer be sucked in when zipped up and you can use the horizontal poles to anchor netting to effectively train your plants

2 Expandos included in each pack – we recommend installing at least one on each wall of your tent but they can be used on ceilings too!

The Expando V2 offers a similar performance to the older model in a more robust & reliable package that can withstand high negative pressure. By pushing the edges of the tent out, you bring many benefits to your garden, including:

  • Higher yields due to increased space for plant growth
  • Uniform growth – no hotspots & more reflected light directed to the canopy
  • Better airflow – Increased transpiration rates and reduced chance of mould

The Expando V2 has taken lessons learned from the original to create a more solid, durable grow tent space booster. Now with stronger aluminium poles and new securing mechanism, ensuring it will not move once attached.

Able to handle high levels of negative pressure the Expando V2 is becoming a grow tent essential to maximise your space and make the most out of all your other equipment.

How to use Expando V2

Only suitable for use in tents with a pole spacing between 1m – 1.5m2

Fits most tents with poles between 16mm – 30mm

Simply assemble the Expando, clamp it between your poles and tighten the clamp to secure.
