GYO 4x4 Ebb & Flow Pro Package

This system is inexpensive & easy enough for a beginner but yields up to 48 massive plants with little/no odor!

A bad-ass, high-performing ebb & flow hydroponic system with nutrients, lighting, tent, circulation & exhaust fans, odor control and Carbon Dioxide (CO2) enrichment! In the ebb & flow method (also known as the flood & drain method), the plants sit in their own container separate from the nutrient reservoir. On a set schedule, a pump transfers the nutrient solution from the reservoir to the planters where the plants are located, soaking the plant roots and the grow medium. After the feed cycle, the nutrient solution is returned back into the reservoir. This setup is perfect for growing a lot of massive plants on 1 central reservoir!

Grow System: Grow Flow ebb & flow hydroponic garden with 5 gallon modules

Active Aqua's Grow Flow is the most efficient ebb & flow system on the market. The fill and drain cycles are maintained by the controller unit and set with the built-in timer. This system can be set up in many different sizes and shapes to fit your exact growing needs.

Grow Flow is the only unit on the market with fail-safe overflow protection. If the float valve stops operating, the emergency shut-off valve will automatically power down the system, preventing any spillage or damage to your growing area. At the same time, the LED indicator light will light up on the control panel. Since your pumps are only pumping a short time each day, the system is extremely reliable and efficient.

  • Adjustable float ladder
  • LED emergency indicator light
  • Concave center drain buckets are engineered to fully drain, no more stagnant water in the root zone

Environmental Controller: Greenhouse Master Controller

The Autopilot Greenhouse Master Controller (GMC) is designed to precisely control temperature, humidity, and CO2 in the growing area.

The GMC's enclosure features four separate power outlets used to connect external devices such as fans, CO2 injectors, air conditioners and dehumidifiers. Each external device easily connects to the unit creating a simple and user friendly platform.

The GMC's fan-powered remote combination probe features a highly accurate dual beam CO2 sensor. The remote sensor can be placed up to 15 feet from the controller and has been designed to resist EMI / EFI from electronic ballasts.

Each unit has been pre-programmed with factory recommended settings for quick plug and play operation. Autopilot controllers offer grow room guidance.
