Worse than USELESS. Too little turf. Lousy seed germination. Waste of time, effort and money.
Im not sure what the other person didnt do in their review, but I 
Didnt know what to expect.
The dirt cubes work AWESOME!
Simply read 3 step directions meant for a child really. I let the dirt cubes soak in plastic mini bags awhile in water, then went back and placed them in pockets half of the dirt cube then sprinkled seeds the other half of dirt cube
Even tried all dirt, seeds on top, then mixed w my fingers. Both methods worked great. Natural rain and a misting wand each day for only a few seconds. Be careful not to overwater or I could see how water might overflow pockets & seeds may escape in first couple days.
Wasnt a problem at all.
It was like a 6th grade science project that literally took a few mins.
I used zip ties & zipped them to my metal porch railings.
I even bought extra dirt cubes and tried with my own seeds & it worked!
I found that you just leave in the miracle dirt, dont add any real soil until after able to maintain growth on its own.
I will definitely buy more next time.
Thanks Woot!
Exactly 7 days later they looked like this!
