On Saturday, December 29th, two carloads of brethren traveled to near Jogja to learn about hydroponic gardening. The event was sponsored by Hendro and his wife Berta and they held it at their restaurant (under construction).
The presenters were able to teach and demonstrate several hydroponics methods and showed many types of plants that are appropriate for this method of cultivation.
Small and simple and straight-forward .... especially for starting new plants.
A little more complicated for larger vegetables.
And even more complex, depending on the space available or if a commercial setup is being considered.
