Q: What is the thermal conductivity of vermiculite and vermiculite?: Vermiculite is a kind of hydrate, which is blocky, flaky and granular. It is the product of weathering and alteration of natural mineral such as biotite. The interlayer water molecule is ignited at high temperature, and the volume is increased by 18-25 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients.

Q: you put 25 grams of iron powder and 1 gram of salt in a resaelable plestic bag, and add 30 grams of vermiculite to the bag, seal the bag, shake it to mix the contents, then add 5 Ml of water to it and mix the contents again. what happens?????: nothing, the salt water will NOT react with iron, however the rion will just replace a few of the ions of the mineral and still probally nothing will happen

Q: A gardener needs 6 bushels of a potting medium of 40% peat moss and 60% vermiculite. He decides to add 100% vermiculite to his current potting medium that is 50% peat moss and 50% vermiculite. The gardener has 5 bushels of the 50% peat moss and 50% vermiculite mix. Does he have enough of the 50/50 mix to make 6 bushels of the 40% peat moss and 60% vermiculite mix? Explain.: He will use x bushels of 50%, and 6 - x bushels of 100%. The result will be: .50 * x + 6 - x .6 * 6 3.6 -x/2 -2.4 x 4.8 4.8 bushels of 50/50 mix contains 2.4 bushels of pure vermiculite adding 1.2 to make it 6 and you have (2.4 + 1.2) / 6 3.6 / 6 bushels of pure vermiculite 60%. He can also do it this way, using his whole 5 bushels: Let x amount of 100% vermiculite to add. 5 bushels of 50% vermiculite 2.5 bushels of pure vermiculite. 2.5 + x .60 * (5 + x) [ existing vermiculite + added 60% of total ] 2.5 + x 3 + .60 x .40 x .5 x 1.25 bushels added. Then he will have 6 1/4 bushels of the new mix. which will be 60% vermiculite. ( 3.75 / 6.25 0.60 ) If he then throws away 1/4 bushel of the new mix, he will have the desired mix in the desired quantity.

Q: ineed to know every equipment i will need: it was magic. you need some weed ;)

Q: It probably is and I‘m really upset about it.So my lizard laid the egg in the sand and I carefully moved it into a little plastic container. I used Vermiculite for the substrate, added a little water to it to not make it dry, and placed it in the same catch as my leopard geckos. ( It has a top on it )The thing that get‘s me thinking that it‘s already bad, is that it seems like it has a cut in it or something- kind of like it‘s leaking. The colour is clearish white and I don‘t know what to do about it. Please help. :(: If the egg has a cut in it and is the white is leaking out, it will not hatch.

Q: The rents are re-renovating my house, (it was built in the fifties) and we found some vermiculite in the attic. We know that they used it for insulation, but we want to remove it. I was wondering if it was cancerous. And if it is, if there are any safe ways of removing it?: I had a hardwood furnace for over 30 years in Northern Minnesota. I had a twelve foot triple lined ten inch chimney through a block chimney. I never had a problem with creosote. The chimney burned cool enough to stop the creosote and it would fall to the bottom, I would clean it out in the spring. I did use flares for safety to make sure it stayed clean.

Q: Can vermiculite be used for making flowers?: Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil. In 2000, the total output of vermiculite in the world exceeded 500 thousand tons. The major producers are China, South Africa, Australia, Zimbabwe and the United states.

Q: you put 25 grams of iron powder and 1 gram of salt in a resaelable plestic bag, and add 30 grams of vermiculite to the bag, seal the bag, shake it to mix the contents, then add 5 Ml of water to it and mix the contents again. what happens?????: nothing, the salt water will NOT react with iron, however the rion will just replace a few of the ions of the mineral and still probally nothing will happen

Q: hi i want to know what substrate i can use other than vermiculite and perlite because i cant find any of those substrates pleas help?: Peat moss works fine. :)

Q: What can vermiculite be used instead of?: The principle of preparing nutritious soil is to suit measures to local conditions. Not all nutritious soil for growing flowers has vermiculite. As long as the soil does not harden, but also to maintain water and fertilizer is the best. Generally speaking, rotten leaves are the best. They are better than vermiculite. But the decaying soil will decay over time, and the volume of culture soil will decrease gradually.
