Ventilation plays an important role in greenhouse growing. Vertical airflow (VAF) fans produce an air current that is forced outward and downward along the ceiling and sidewalls of the greenhouse and then is moved upward through the crop. Using this type of greenhouse fan can create a much better and more uniform climate and it can also lead to energy savings.
Works well -- fans run smoothly.
Love It!! My tropical plants in my bioactive vivarium are absolutely thriving🌿💚!
Pump works as advertised. Fairly quiet. Works great for making 5 gallon buckets of aerated compost tea.
This bat guano is great! I made guano tea and fed the plants. They are a wonderful shade of green and are growing taller and thicker. I am very happy!
Great product and a great price
