Time well spent in the garden.

I'm pretty impressed by the fact that I can spend a couple of minutes planting some seedlings and they give me so much back with how long they last and the joy of eating your own garden or seeing flowers you've grown and the birds or insects they have attracted.

I guess that's a pretty obvious statement in regards to gardening, but I was thinking about food plants and how simple it is to grow a few little things that can help your vitamin and mineral intake immensely.
If you can get your hands on some seeds or seedlings, soil, fish emulsion and kelp solution, you can grow some lettuce or parsley, chards, and with enough sun all kinds of veg are easy to grow as long as you can water and feed them. This isn't so easy with water restrictions, but a watering can will suffice, especially when it has fish and seaweed in it every couple of weeks.

Reusing Kitchen Water.
The double sink in our kitchen has basins in it to collect our washing up and rinsing water. One side has the clean water, which can go onto plants out the front, near the door.
The rest of the water goes into a large bucket that also has our kitchen scraps.

Any edible-ish scraps are collected for our dogs, who get blended leftovers and veg as their meal a couple of times a week. They especially like it if there's a bit of cheese or meat scraps or a tin of sardines in it.
