Early Aquaculture Experiments 2

The two pictures shows what is a plastic shoe box used for aquaculture. The box was painted an opaque brown. The two large Myrtillocactus geometrizans are the same two in the first page on my early experiments.

This picture shows the roots of the specimens. The roots are brown in colour, probably dying of suffocation. This happens if the solution in the box is not renewed. Still, it is possible to keep plants on the same solution for 1 to 2 months with no ill effects.

The roots of the Echinopsis and the Myrtillocactus specimens are very strong and tough. The roots of the Aloe however, is usually thick, fleshy and rots easily. On the other hand, the shedding of roots might be normal behaviour. Haworthias do that, I believe. Still, it is possible to grow an Aloe in aquaculture.

At left is a picture of a flowering Huernia verekeri in a hydroculture container. No special nutrient concoction was used. The plant has since bloomed regularly in the container. It has quite thick and long but fragile roots. It's the same one as in Page 1.

Below are pictures of various specimen out of the solution. The roots are shown.

The first picture is an Echinopsis. It puts out masses of roots quickly, and the is quite resilient to rotting. The next two pictures shows two different Myrtillocactus geometrizans specimens. This species has a trunk-like root system which spreads out, and is tough and resilient too. It's excellent for aquaculture, especially as grafting stock.

At left is a Melocactus. It does not grow as fast as Echinopsis in water but is relatively trouble-free. The plant on the right is a Mammillaria. Many Mammillarias does not produce as much roots as Melocactus and Echinopsis plants when in aquaculture, but I suppose that is highly dependent on the species, its size, etc.

The plant in the middle is an Aloe. As you can see at left, the Aloe has some problems with having its root in water. Its roots are quite thick, soft and fleshy. Most of the root system has rotted, but fresh roots sprout out here and there. It's a little dicey, but the plant does okay.

For my really early efforts, see Page 3 on the subject.
