Container planting - a new strategy?

In an ongoing drive to improve our home garden crops in a drought affected region I decided to investigate the feasibility of the Earthtainer for our back yard.

So I decided to do an experimental ‘earthtainer’, but first some background. A simple explanation of the concept from www.slade .com

The EarthTainer is a "self-watering container," which isn't a novel concept to most gardeners. It's essentially a big pot with two chambers—the top one, containing soil, is where you put your plants, and the bottom one is where you add water. As you can see in the picture below, the two chambers are connected by a central "wicking basket"; through capillary action, water is absorbed from the bottom chamber through the wicking basket and into the top. It's impossible to overwater your plants in the EarthTainer, and it's almost impossible to underwater them, too: You fill it with water every few days, and your plants drink up only as much as they need.

Now what I like about this is you do not get nutrients leeching when watering, and also one can add nutrients to the water.
I bought two cheap plastic buckets with lids and proceeded to cut a hole in the one lid and in the bottom of the other bucket.

The purpose is to house the ‘wicker’ basket which in my case would just be a seedling pot with holes in.

I drilled a hole in the side of the bottom bucket (water container) through which I can add water and nutrients when required.

And assembled the ‘stack’ and filled the top bucket with some seriously poor (lifeless) soil



This was yesterday and by this morning I observed that the top soil was damp, very encouraging so tonight I will plant a chilli seedling and see how the plant progresses.
Thanks for reading and if this is a success I will follow up with a more sophisticated arrangement.
