I like the clever design of honey spinner but PVC is not a good choice for anything that comes into contact with
drinking water or food. In fact PVC is the worst possible choice you could make as far as plastics go. Every part
of it's life cycle is toxic and it out gasses toxins for it's entire life and in the landfill after it's life.
Here are two quotes that google popped up after searching for PVC Health Concerns,

"Both, from both an environmental and health standpoint, PVC is the most toxic plastic.
Here's why: Vinyl chloride, the chemical used to make PVC, is a known human carcinogen,
according to the World Health Organization's International Agency for Research on Cancer (IARC)."

"The natural fire retardancy of PVC is a double-edged sword in that building materials may smolder
for long periods of time giving off hydrogen chloride gas long before visible signs of fire appear.
Hydrogen chloride gas, is a corrosive, highly toxic gas that can cause skin burns and severe long-term respiratory damage."

Here is a link about PVC it's life and concerns.

I am an organic bee keeper and I would not go through the trouble of not using toxins to keep my bee, refrain from
pasteurizing the honey to keep it's enzymes intact and then dunk PVC into the honey.

Most gallon buckets are made with polyethelene and that is a food grade plastic.
I like the clever design and if it could be reworked with food grade materials it would be both
clever and excellent!

I purchased the Lions Mane indoor kit and spawn plugs from Paul Stamets company fungi.com. The kits are loads of fun and watching the mushrooms that look like a mass of ice cycles growing in the comfort of your living room is very convenient. Sauteed in butter they taste like lobster meat. Two years ago I took the plug spawn and my cordless drill to a local park (N. California) when it was raining and did some gorilla plugging on some recently downed oaks. I have seen Lions Mane in this park before so I was not introducing anything foreign, just increasing my chances of harvesting some. It has been droughty the last two years and I have not seen any fruits from my efforts. I may try again this year.

I like this topic, it is all a matter of perspective and how you look at it. I also get a wrench in my gut when people start talking about native plants. I like
that question that Paul and Toby posed," Native to when?". You could also ask ,"Native to where?" How far does a plant or seed travel until it is non native?
If I have dandelions in my yard and my neighbor does not and the wind blows seeds from my yard into a non-native habitat that is six feet away from their
native habitat. . . . well does that count as non-native? If you consider that the majority of plants have, as their highest purpose, the goal of moving into new
habitats. Look at how many ways plants have to move their seeds, wind, water, fur, boots, animal scat etc. Maybe "invade" is not the word, after all, "invade" is
what humans do and were personify plants. Perhaps "pioneer" is the right word. When I talk to native plant advocates I tell them that "plants Succeed" in every
definition of the word. They succeed by surviving in a new area and they succeed as in a sequence or procession of events. This bush creates shade that allows
this tree to grow, that trees leaves create a soil that allows the next plant in the procession to grow and makes the conditions right for the next plant etc. When I
was in Hawaii, the native plant society in Hawaii was all up in arms about Lantana. Sure people need their fight (i guess) but Hawaii sprang out of the ocean and is
an island surrounded by water. There is not a single native plant on the island. The whole purpose of plants is to go where they have not been.
Plants do not "invade", people invade. Plants Succeed.

Below 4.5 metals can become soluble especially if the water is hot. This can make copper and lead solder from older pipes in the system more available. You can raise the pH of water in a tank by adding limestone. It does not take much, a small brick size should do it. The lime stone is soluble in soft or low pH water and will dissolve until until the pH reaches about 6.5 at which point the limestone is no longer soluble. In aquaponics this is done by using crushed oyster shells or limestone suspended in a paint strainer or pantyhose in the fish tank. It helps stabilize the water pH and adds calcium to the water. I looked for a reference and found this article on a site that sells filters http://www.triangularwave.com/f7.htm It does a pretty good job explaining this.
