Update 30th Oct 2010

Quick update.
Cherry Tomatoes recovered and once they did, the grow rate is phenomenal. 
Check their size on 14th October  : Here   26th September : Here

Estimate about 45 days its start to flower.

 All plants started to flower at same time, and this tomatoes I don't practice any pruning.

Maize flowering too, male flower coming out on one of the two plant. Female corn flower should be coming out on the stems together with baby corns. We'll see how it goes, I hope to see the corn developing.

This guy below is PR of the maize plant. We have an agreement, if he don't eat too much I'll let him be.

So far he's keeping his part of the bargain.

Single Barrel Aquaponics - Update 24th Oct 2010

I decide to redo my single barrel kit, the 15mm siphon requires too much water tweaking. It requires very small water inlet, I did divert excess water but since the pump is small it tends to clog easily.

Those Tomatoes plant show sign of yellowing leaves. I need to check water PH, adjust  and may add iron in water to reduce the yellowing.

Two changes done since last update on this set. Water inlet I redo from bottom and feed through to top of growbed, no more ugly pipes on the outside.

Another changes,  15mm siphon I replace it with 20 mm siphon, this able to use all water from the pump without diverting.

I also put a timer, to switches OFF at night, this will reduce pump maintenance and chances for it to fail is less.

Water has been clear, not much sediment, maybe because of few fish in this tank.

More to do on this kit to ensure it is able to produce comparable plant growth.

Gaetan Dureau - Aquaponics

Received few photos from Mr Gaetan Dureau on his aquaponics set in a small village located  North Eastern part of Thailand near city of Khon Kaen ,its interesting  to see how it was all constructed and put together.


I do not have much information on how all was done and as he mentioned its still newly build and still cycling.


Here are some of the photos.


Just a note from what I could deduce, those cement will make Alkalinity shoot up,  plus limestone use as growth media will cause water PH value sky-high, just ensure this set is cycled properly before putting fish or plant.


I recommend pineapples peeling or vinegar or lemon be added to water in tank for about a week to bring the PH to below 7.5.
