The Uniheat 72 hr shipping warmer is recommended for orders that are being shipped to colder climates. They do not guarantee that your plants will not freeze, but we have never had a problem when using them. Once activated, they will provide warmth to your package. If temperatures are very low, we recommend holding your order and shipping once temperatures rise.
Most orders require only 1 Uniheat pack. If your order is larger and requires additional heat packs, we will advise you prior to shipping.
Heat packs ship free with your online plant order.
