I have recently been commissioined to build a small Aquaponic system for a B&B in the forest near Knysna. The intention, is that this system will eventually become a training facility and I will conduct Aquaponic (AP)courses from the site. The delegates will stay at the B&B for the duration of the course and learn AP in a lecture room environment as well as hands-on in this training system.
Like all other systems, this one starts with a “rough” plan. Here it is;
Briefly, it consists of two areas. The first is a 6m x 3m hobby tunnel in which we will have a small 1.8m diameter (1.2m deep) mesh pond and 4 x 3m growbeds. The second is an area of similar size, but under shade cloth. Here there will be a 3m diameter (1.2m deep) mesh pond and 4 x 3m growbeds. A 5000L tank at a lower level will act as the sump.
The area chosen is an existing terrace which we are widening. This area was previously used as a vegetable garden, but with the drought and regular raiding by baboons and monkeys, it has fallen into disrepair. Here is what it looked like before I started.
And here is what it looks like after some clearing and compacting was done.
After two weeks work, we have achieved the following;
- Cleared and compacted the terrace.
- Cast a slab for the sump at the lowest point and placed the sump.
- Cast a slab for the smaller tank which will be inside the greenhouse tunnel.
- Planted the poles for the shade cloth area.
- Constructed the greenhouse frame, levelled and concreted into place.
- Planted the poles for the growbed stands.
- Unrolled and bolted together the mesh pond frames.
Here is about where we are now.
I will be sure to keep you posted.
