    Great seed starter trays!

    I was researching products to get away from the Jiffy trays I've used in years past - flimsy, cracking and not holding up from year to year. I found Bootstrap Farmer (recommended on Instagram by a farmer in Ireland!). This is my first year using them but they are very well made and super durable. Looking forward to trying other bootstrap products!

    Excellent high quality product!

When I called, it was before they opened for that day, but, a young man answered the phone anyway. He was very helpful.

    50 Cell Seed Starter

    Using this system has made my seed starting so much more efficient than using the flimsy starter sets from big box stores. I will be adding to collection in the future.
