This has become a family entry! Richard Whitaker (my father) has become very passionate about the idea of vertical vegetable gardening, and has been building things at a rapid rate. In this log I'll put photos of some of his contraptions.

1) A bottle spiral. This early design is going to be much improved in a later version.

2) Water poured over the gravel is wicked up by the plants. Good for leafy greens and lazy gardeners!

3) Who says tomatoes need to grow out of the top!

4) A bottle rack. Each bottle can click in and out independently. One of the nicest systems so far, and these milk bottles are a very common type of trash.

5) A pretty herb garden

6) Hanging tower of bottles - water in the top trickles down and waters all the plants.

7) A sports themed salad bar (bottles from unclaimed lost property)

8) Can tomatoes be grown in less than 2 kg of soil

9) How many tomatoes can be grown in 10 kg of soil?

10) A strawberry pot with a moisture retention system.

It's crazy how quickly all this was thrown together, literally out of trash. Way to go team Whitaker! Can't wait for @David Whitaker to add in what he's been up to :)
