Titan Controls Flo-n-Gro: Ebb & Flow Gro System, 12 Site

Additional Images


The 12 site Flo-N-Gro system is built with the Oceanus 1 controller which was designed to be simple to use. The system allows the grower to have the flexibility of an ebb and flow garden with minimum maintenance of their hydroponic system.

The Flo-N-Gro is an expandable multi-site hydroponic system that incorporates a flood and drain growing method. When the Oceanus 1 controller is activated, oxygen rich nutrient water enters the GRO sites and soaks the root zone by flowing through the 360 degree mesh inserts. The water is then returned to the main reservoir, waiting for the next watering cycle.

Product Features:

  • 55 Gallon reservoir
  • 12 - Four (4) gallon GRO sites
  • 12 - Three (3) gallon 360 degree mesh aeration inserts
  • 1 - Oceanus 1 Flo-N-Gro controller (Item #: 702780)

Titan Controls Flo-n-Gro: Ebb & Flow Gro System, 12 Site Questions & Answers

My Flo-N-Gro won't stop pumping water and the system is flooding?

There is a 1/8" siphon hole in the straight fitting that goes into the top of your reservoir. It is just under the top of the lid drilled into the side of the straight fitting. If this hole is covered by the fill hose, the system goes into a constant fill mode and can flood. If you back down the 1/2" tubing and expose the siphon hole, your system will function correctly.

I have 8 Flo-N-Gro GRO sites on a single run and they do not fill evenly before the FILL cycle is completed?

The 3/4" tubing can constrict the water and will not fill all the GRO sites evenly if there are too many sites on a single output port . If possible, try to run even numbers of GRO sites on each output port. For instance, run 2 lines of 4 GRO sites or better yet, 4 lines of 2 GRO sites, and you'll find that they will fill more evenly.

My timer does not seem to be working properly, it just keeps blinking?

The power plug acts like an ON/OFF switch in this product. Always make sure that your Oceanus 1 is unplugged before setting or adjusting the timer. Set your feeding schedule, then set your correct time of day, and then plug your power plug back into a 120 VAC outlet. Oceanus 1 will maintain time and schedule until the power is defeated.

Do I need to clean my Oceanus 1?

Yes, you should clean your Oceanus 1 completely between each crop. For example, you can use a few drops of antibacterial hand soap to clean the Oceanus 1. Just make sure you thoroughly rinse (minimum of 3 times) the Oceanus 1 to remove all soap and debris before using.

Simple Fixes Review by Billy Bob
I would recommend the 12-site system overall,

As for the site itself, assembly is pretty simple and fast where one person can set it up solo. That's a convenient feature. The pumps work pretty well, but sometimes the upper tube on the inside of the 55 gallon water canister comes undone.

This is usually due to the recommended and effective use of cooking oil used as lubrication in order to place the tubes with an ease. The trouble is this makes the tube a tad bit prone to come off and unclamped and then your plants suffer especially the younger ones due to the loss of nutrients and water. So this system requires much more attention than you are paying for. I was able to remedy the tube with a zip tie and if done correctly this method is extremely efficient.

The pumps are excellent and the timer fully functional makes the watering extremely simple for nearly anybody to use. The metal hatch on the lid is relatively difficult to open and the aluminum clip bends in the wrong direction after about 4-5 times of taking the ring off.

The suction cups are not attached well to the pumps causing them to fall off and land at the very bottom of the water and near impossible to retrieve. That said the pumps work very well and are quite effective but make sure and use the recommended grow cubes/croutons which Flo-n-Grow offers on-line or can be found at most any hydroponic shop.

As far as the tubing system it is air tight rock solid and does not leak one bit. Recently I have found better pumps out there for a lot less money, so remember to shop around.
