Very good for our hard clay type soil.
I have never been able to grow vegetables so successfully before. We use it in our "high tower" type greenhouse which we planted in March. I have spinach like I never had before along with kale, beets, radishes, lettuce and carrots. I have started all my plants to put outside using vermiculite mixed in with my soil. In my garden we just mix it in along the rows when we plant. And to think it is only May and we are enjoying our vegetables in NH.

Just the ticket!
I used this in my raised bed garden along with perlite and compost/topsoil mix. Just the ticket! Don't use on windy day. Use a dust mask, fine particulates.

1/3 of Mel's Mix for Square Foot Gardening - exactly what I needed
I searched around for large bags of Vermiculite and landed at Home Depot Online for the best deal. The All New Square Foot Gardening requires Vermiculite as 1/3 of Mel's Mix - the essential mix of soil for this amazing gardening method. The Vermiculite is very light an airy, but holds water in close to the plants roots. It was easy to mix with the other ingredients and is exactly what I needed.

Brick Oven Builders
Hi All....
Anyone that has tried to build a brick oven will know that getting this stuff in large quantities can be very difficult. When mixed with portland cement... 6-1-1----- 6 vermiculite, 1 part portland cement 1 part water, this makes an incredible insulator for the dome...then covered with mortar or I used SBC (surface bonding cement) will keep the heat in for some fantastic baking.. Also can be used to line fire pits.. Thanks home depot for another great product, Just wish you would carry it in the stores,,,,, you can see in the pic that the oven is so well insulated the snow wont even melt... that was after 4 hours of fire... I wish they would start carrying Fire brick and heat stop mortar as well, then it could all be bought in one stop from a trusted friend.......
