Blocks the negative-pressure effect that pulls grow tent walls inwards under full extraction. Your usable volume and airflow stay constant for healthier plants.
Bars slide directly into the upper corner sleeves of your HomeBOX. No screws, no tools, no fuss - just clip and grow.
Engineered to HomeBOX original specs and also fits most 80 cm grow tents from competing brands. A complete set for one side of the tent.
When your extractor creates a vacuum inside the tent, the fabric walls collapse inward. These telescopic bars stiffen the frame, prevent deformation, and preserve usable space for your plants and lighting.
Will they fit my HomeBOX 80x80?Yes - this 4-pack of 80 cm bars with a 16 mm diameter is designed for HomeBOX models with 80 cm sides. If you're unsure, message the BloomLED team and we'll confirm compatibility with your exact model.
A well-tensioned HomeBOX means stable, quiet, and long-lasting indoor cultivation.
