Great for GreenStalk!

Two cubes (with some leftover) perfect to fill 5 tier leaf planter.


I have used this product for all my seed starting and I have to say I've gone from failure to 100% success with it. I'm not a pro at gardening but I have been gardening for many years so between this product and the seed companies I use now(super important) I can say this, BUY IT. I am not joking and it is pricey but add it to your gardening budget and you can buy less seed. I used only 1 seed per cell this year to experiment with my seeds and this soil. Only 2 of 60 didnt germinate. There is my 2 cents.

Love this product

Not only do I love it, I recently asked a client to purchase 8 cubes for her home in Park City, which she did and another is about to place an order for 12 cubes! It is very dry in Utah this year...thanks for helping stretch every ounce of water! My transplants have loved their new environment!!
