Protect your order from the winter cold with this UniHeat shipping warmer. Designed for reliable and steady heat release for the entire transit time of your shipment.
When to add a heat pack:
If you expect temperatures to dip below 40 degrees when ordering, we highly recommend adding a heat pack to your order. If temperatures end up being warmer, don't worry! Your plants will not be harmed by the heat pack as they release steady heat only and will not "cook" or "scorch" your plants in any way.
