Spider Farmer 4-Inch Inline Fan 205 CFM with Smart Controller
Achieve superior airflow and climate control with the Spider Farmer 4-Inch Inline Fan. Featuring a powerful 205 CFM airflow, this fan efficiently circulates air, helping maintain ideal temperature and humidity levels in your grow tent or indoor garden. The included Smart Controller allows for easy, precise adjustments, ensuring your environment stays optimal for plant growth. With quiet operation and reliable performance, this fan is perfect for small to medium setups, making it an essential tool for any grower looking to enhance their space’s ventilation and air quality.
【Quiet & Powerful】 Mixed flow design combined with an EC motor that powers high-quality impellers makes this fan truly energy efficient. With only 27 watts of power but a strong airflow of up to 205 CFM, a very low noise level, and only 26.8 DB, this 4-inch exhaust fan is silent. Lightweight ABS blades reduce the airflow resistance and add airflow by 40%.
【Intelligent Controller】The smart controller has multiple modes for operation, 10 fan speeds, is easy to program, and controls the humidity and temperature automatically. Easy to control over the fan speed, airflow, and many other elements, stabilizing and optimizing your growth environment.
【Temperature Regulation】 Inline fans help maintain optimal temperature levels by removing hot air and exchanging it with cooler air from the outside. This prevents overheating, which can damage plants and impede growth.
【Humidity Control】 Proper humidity levels are essential for plant growth. Inline fans assist in regulating humidity by exhausting stale air containing excess moisture and bringing in fresh, drier air. This prevents the development of mold and mildew, which thrive in humid conditions.
【Air Circulation】 Good air circulation is vital for plants to receive an adequate supply of carbon dioxide (CO2) and to facilitate the process of transpiration, where plants release water vapor through their leaves. Inline fans ensure that CO2 is evenly distributed throughout the grow space and that plants receive sufficient airflow to support their growth and development.
【Pest Prevention】 Proper air circulation can deter pests by creating an environment that is less conducive to their proliferation. Additionally, inline fans can help to remove airborne pests that may otherwise settle on plants and cause damage.
【Daisy Chain Programming】 Two fans can daisy chain together to share the same controller, the long corded design greatly facilitates the fan connection and installation

Who We Are
At Garden GrowShop, we're not a faceless online retailer. We're a small, family-run business with real roots in the growing community. Every product we carry has been carefully chosen to meet the needs of both home growers and commercial operators — because we’ve walked in your shoes.
Personal, Knowledgeable Support
When you reach out to us, you’re not getting a canned reply or being passed between departments. You're talking to someone who actually knows the products, understands your challenges, and is here to help you succeed.
Transparent Pricing — No Gimmicks
We believe in fair, honest pricing. No inflated markups, no bait-and-switch tactics. If you ever find a better price on the same item, let us know — we’ll match it without the hassle.
Fast, Dependable Shipping
We ship directly from warehouses across the U.S. to get your order to you quickly and reliably. No inflated delivery timelines, and no surprise shipping fees — just smooth, on-time delivery you can count on.
A Partnership, Not a Transaction
Our customers stick with us because we treat them like partners. Whether you're outfitting a small indoor setup or managing a large-scale operation, we’re here to grow with you — not just sell you equipment.
Our Commitment
If something goes wrong, we don’t pass the buck. We work with you directly to make it right. That’s how we’ve built our business, and that’s how we plan to keep it.
We offer free shipping on all orders over $200 shipped to addresses within the continental United States. Orders under $200 will have shipping calculated at checkout. There are no hidden fees or handling charges. The price you see at checkout is the final price you pay.
Orders are typically processed within 1–2 business days (Monday–Friday). If an item is temporarily backordered or delayed, we’ll notify you by email with an updated shipping estimate.
Once your order has shipped, we’ll email you a shipping confirmation that includes tracking information. You can use this to monitor the delivery status of your package in real time.
We partner with trusted suppliers and manufacturers who maintain warehouse locations throughout the United States. Orders are typically shipped from the facility closest to your delivery address to ensure faster transit times and greater efficiency. Some orders may ship in multiple packages depending on item availability and warehouse location.
Most orders arrive within 3–7 business days of shipping, depending on your location and the item’s warehouse origin. Freight items and oversized packages may take additional time.
We use trusted carriers such as FedEx, UPS, USPS, and professional freight delivery services for large or heavy items. Depending on the size of your order, it may arrive in multiple packages or from multiple warehouses.
Please note: We do not offer moving or installation services. For freight shipments or large items, carriers are only responsible for curbside delivery. Drivers are not required to move items inside your home, up stairs, or to specific locations. We strongly recommend having assistance available at the time of delivery for heavy or bulky shipments.
Please ensure your shipping address is correct at the time of checkout. Once an order has shipped, we are unable to change the delivery address or reroute the shipment. If you need to make changes to your order, contact us immediately after placing it.
If your order arrives damaged or appears to be lost in transit, contact us within 48 hours of delivery (or expected delivery). We will work with the carrier to resolve the issue as quickly as possible.
We currently ship only to addresses within the continental United States. We do not ship to Alaska, Hawaii, U.S. territories, or international destinations.
If you have questions about your order, delivery, or shipping process, feel free to reach out to us through our Contact Us page or via email (sales@gardengrowshop.com ). We’re here to help.
