Upgrade your Vertical Microgreen Farm

Grow Healthier Plants
Flooding and draining ensures a steady flow of fresh oxygen for plant roots to stimulate healthy and fast growth.

Automate Your Watering
The siphon works in both continuous and timed flood and drain cycles. It can work with or without a timer.

Grow more vertically
With 1 siphon per tray, watering can cascade from one tray to the next and create a waterfall effect. Water all levels using only 1 pump.
How it works

1. Water is pumped into the top grow bed.

2. Water fills the top bed to a height of 1". The siphon starts.

3. All the water is siphoned from the top bed to the one below. Then, the bottom siphon starts.

4. Water continues to cascade down each level until it reaches the water reservoir.
SIPHON Features

Works with large and small grow trays
The siphon starts and stops installed in a 4 feet x 2 feet grow tray.

Works at 1" water height
Calibrated to start siphoning at 1 inch water height.

No Timer Required
Water can continuously cycle in the system and periodically flood and drain each tray.

Works with multi-level tray setups
The siphon can start with water flowing from another siphon to create a cascading watering solution.

No need for overflow valve
Ebb and flow kits require 2 holes to function. (A drain and overflow). Our siphon only requires one.

Quick flood and drain cycle
Roots can be saturated and water can drain quickly at 400 GPH. Fast flood and drain cycles force out staleness around your plant's roots and pulls fresh oxygen back in.
