Uniheat 40 Hour Shipping Warmers are perfect for adding to your plant order in winter months. All our houseplant orders use a 24 hour (Next Day) courier service, meaning 40 hour heat packs are a perfect addition.

We recommend 1x heat pack per plant as it allows us to place it near the pot of each plant and keep its core warm.

• Our boxes contain handle holes to allow for couriers to safely handle the boxes and keep them the right way up. This also aids the heat packs, allowing them to provide an ambient temperature without allowing too much heat to build up.
