The Spider Farmer® 4″ Inline Fan is designed to deliver powerful, efficient, and quiet airflow for grow tents, hydroponic rooms, and indoor grow spaces. With smart control options and GGS compatibility, it keeps your environment stable so your plants can thrive.
This inline fan removes hot, stale air and brings in fresh air, helping to regulate both temperature and humidity. The result is a healthier, more productive grow space with reduced risk of heat stress, mold, mildew, and pests.
