Who This Is For
- You are installing air socks because standard ducting creates hot spots that make your canopy growth inconsistent.
- You are scaling your layout because manually moving floor fans to fix dead zones is a waste of daily labor hours.
What We Found
- The LDPE material is surprisingly thick, so it does not tear easily when you pull it through tight ceiling grids.
- We find the air distribution is most uniform when the 400 foot sock is kept taut and free of sharp bends.
What Users Say
- Facilities using these socks report much more consistent humidity levels between the front and back of their rows.
- Commercial operators say the precut holes saved them days of manual labor compared to punching holes in bulk poly.
TrolMaster Aero-Fan PS-4 4-Inch Poly Air Sock
Standard duct ventilation often delivers air in concentrated blasts that create temperature and humidity hot spots across the canopy—the opposite of the uniform environment plants need for consistent growth. The TrolMaster Aero-Fan PS-4 Ventilation Fan is a high-performance 4-inch Poly Air Sock, featuring a 400-foot LDPE distribution tube engineered to solve microclimate issues at scale. By diffusing air gently through precisely spaced outlets, it ensures every plant in your facility receives identical environmental treatment.
Constructed from durable, odorless low-density polyethylene, the PS-4 is designed for commercial longevity and plant safety. It features 0.5-inch holes at 16.5-inch intervals to distribute air evenly across the entire grow space, eliminating dead zones without subjecting plants to damaging high-velocity airflow. This system pairs perfectly with the TrolMaster Aero-Fan V-6 Ventilation Fan to create a complete, uniform air distribution network that optimizes VPD and transpiration.

FAQs
Which Aero-Fan model is the PS-4 designed to work with?
The PS-4 is a 4-inch air sock specifically designed to pair with the TrolMaster Aero-Fan V-6, which shares the same 4-inch duct connection. Together, they create a comprehensive air distribution system for commercial environments.
How are the air holes spaced, and why does it matter?
The PS-4 features 0.5-inch holes spaced at 16.5-inch intervals. This precise spacing is critical because it ensures airflow is released consistently along the entire length of the tube, eliminating the microclimates and hot spots often found with single-point ventilation.
Is the LDPE material safe for use around edible crops?
Yes. The PS-4 is constructed from odorless low-density polyethylene (LDPE), a material that does not off-gas harmful compounds, making it perfectly safe for sensitive crops, herbs, and vegetables.
Can the PS-4 be cut to a shorter length?
Absolutely. The 400-foot LDPE tube can be cut to any length required for your specific grow room. Simply trim the material and seal the end to maintain proper internal air pressure for distribution.
How does this improve canopy health?
By distributing air through hundreds of small holes, the PS-4 provides gentle, low-velocity airflow. This promotes better gas exchange and consistent VPD (Vapor Pressure Deficit) across the entire canopy without causing wind burn or foliage damage.
