Horti-Shield Bug Blockers
One of the main way pests (like greenfly, whitefly & aphids) get into your grow room is through your intake fan.
Keep pests out with a Horti-Shield Bug Blocker. They’re simple yet effective...they don't cost much either!
They won’t affect your airflow rate – simply secure one over the inlet of your intake fan using the handy drawstring. Easy.
During warm weather they’re a must – it’s when insects are most prevalent, and when you’ll be drawing in the most air.
