Silica in Vermiculite?

Post  Sharpy on 3/2/2010, 11:26 pm

I located the big bags of vermiculite at Menards, it is manufactured by Sun Horticulture but it is sold as insulation. It states that it contains only vermiculite with up to 1% silca?

Is this the right stuff? Is it ok to have silica in my Mel's Mix?

Silica in vermiculite

Post  WardinWake on 3/3/2010, 12:24 am

Sharpy:

From Wikipedia, the free encyclopedia.

The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. Silica is the most abundant mineral in the Earth's crust.[1][2]

Yep, silica is OK in the SFG.

God Bless, Ward.

Silica in vermiculite

Post  Kabaju42 on 3/3/2010, 9:35 am

Sand is mainly made of of silica, so your bag is basically vermiculite with a touch of sand. I doubt that would hurt the plants at all.

I found this at my local Menards as well. Just to be sure I emailed Sun Horticulture to make sure it would work in my garden. Here was their reply:

Hello Tony
Thank you for contacting Sun Gro. If the vermiculite you purchased from Menards is labeled either Sun Gro or Stronglite or Sunshine, the product is safe to use in your garden. It is identical to other vermiculite other than the size may be larger than what is often sold for gardens.
Happy Gardening

So it sounds like it might be a little more coarse than most but should be fine. Good deal because $10.99 for a 3 cubic foot bag sounds like a much better deal than the only other place in town that had it for $26.99 for a 4 cubic foot bag.
