I love the idea of using iodine instead of chlorine. Our diets are deficient in iodine (unless you eat a lot of seafood). If you don't like the smell of the iodine (which most people perceive as a taste), just crush a Vitamin C tablet and add to the water, reseal the bottle, and give it a shake. The color, smell and taste will all be gone! The iodine is still in there but now it's bound to the Vitamin C and you won't notice it. Nice Instructible!!
I see particle board and plywood - I was told that the adhesives used in their manufacture is harmful to bees. Have you noticed any ill effects? There are lots of people who will 'warn' against things that turn out to be harmless, so this is a question, not a criticism!
There's an old rule-of-thumb that says you should use vegetable oils on timber, mineral oils on metals, and animal oils (includes fats) on leather. I'm not sure how much of a bad effect mineral or vegetable oils would have on leather, but as leather is usually quite expensive, I don't want to take the chance. Beeswax is fine. To soften it I'd be inclined to use pure neatsfoot oil - also animal based. The few drops of lavender or tea-tree oil wouldn't be a worry.If you're looking at 'oilskin', which is usually cotton, I'd go for vegetable based oils.
What comes after Step 1?
Sure, I'll correct you. Tomatoes are a fruit. Although that is a technical distinction, tomatoes were first used as a dessert fruit, and only within the past 100 to 130 years started being used in salads etc. My own grandfather used to grow beautiful sweet tomatoes, and we ate them with sugar and cream. We now use them as a vegetable far more than as a fruit, and many varieties now are not very sweet. If you want sweet varieties, many of the 'cherry tomatoes' are sweet. Also old heirloom varieties such as Grosse Lisse are sweeter than modern hybrids.A fruit or vegetable is determined by what part of the plant it is. http://www.livescience.com/33991-difference-fruits...So tomatoes, chillies, and even drumsticks are fruits.
At the risk of sounding hypocritical I've just collected some water hyacinth here in the Philippines. I've retired here, and it's all over the place. I will use it in my aquarium and for my aquaponics, feed young leaves to my rabbits, and mulch the rest for my garden. My aquaponics setup is very small, and it doesn't take much of a change in fish numbers to either starve the plants, or have too many nutrients - I can use the water hyacinth to clean up nutrients, and harvest more plants when nutrients are low.I probably won't have more than a square metre of water hyacinths at any one time. I've read that they oxygenate water too - I'm testing that now.
