Hi Coco
have you checked the website under the hemp mats- you can see broccoli sprouts I grew on them. They work extremely well- far better than sprouting without the mats. Its a shame you didnt try the mat with new fresh or different seeds so you could see for yourself. The mats are used widely both commercially and domestically. I'm sorry you had a difficult experience, don't give up as they definately work. Other factors like seeds, humidity, watering etc can greatly affect success. Please feel free to contact us at sales@naturesnutrition.co.nz for help- I'd be happy to send you another couple for you to try. Happy sprouting :)
