diy aquaponics aquarium | Slotted Pots For Potted Flood Drain Aquaponics

diy aquaponics aquarium


Starting to do more of this potted flood & drain style of aquaponics since it is very convenience and use less LECA. There are pros and cons for doing it this style, however for smaller plants it is ideal and could be one of the best way to do it.
Slotted pots, not sure whether it is a net pot or not but its look good for what I going to use it for. At Rm 2.50 each,  they have slots that is better at draining away water and root growth.

Update : Just found out that these pots is for Orchid plants, so they are Orchid Pots.
Six inches across with no other sizes available from nurseries at Selangor Green Lane, for what I am doing it is sufficient.
Compare to the normal plastic pots, these has more holes and it is just nice for LECA since the slots are narrow but many it will give good drainage.
Just nice for LECA
These are not recommended for large plants, most leafy greens is okay.
Doing one Strawberry since yesterdays almost all I had redo to pots. Ill use this for future potted flood & drain style aquaponics.
Now just wait for these to grow.

diy aquaponics raft system | Going Straight Is Not That Hard Closure

diy aquaponics raft system


I was experimenting with Straight Siphon Outlet by using various reducer. I found that straight, though it work will require more water flow to start off. This more flow require is due to air within the siphon chamber require to be emptied gradually as the siphon about to start.


After experimenting with the above design, I find that to operate a siphon with lower water inflow an elbow is required as in photo below. This outlet shown below is making use of a 25 mm to 20 mm reducer which makes it more stable and reduce noise as well.


This particular outlet style I dont recommend any extension horizontally after this elbow it will cause the siphon slow to cut off due to water lock within this elbow to final water out. What happen as the elbow is during initial siphon starting, water drop down the tube will hit the elbow ad this cause temporary seal, gating the water out and at same time draw air out from above. As the air depleted from the siphon bell it will cause a flush since the gating effect will now draw water downward.


The 25mm to 20mm reducer is just to ensure the siphon is more stable at lower water inflow. Using a 25 mm tube all the way on this arrangement require more inflow, since "elbow gating" will require more water to creates.


This is a closure video of my Straight Outlet that I was experimenting few months ago. It was tested extensively and I find that though it work but it requires more water flow to start. This will make it dependent on water inflow.


The outlet in this video make use of a 25mm to 20mm reducer with a long neck to an elbow at bottom most of the pipe. This elbow form a water gate pulsing to emptied the siphon bell causing flush at lower water inflow as compared to straight flow outlet.
