UniHeat pack, 120 hour warmer. This is also called the mega warmer. This is another option for extra hours of heat.
It’s that time of year... so HEAT packs are up.
Remember that the warmer/heater is really only needed for the LAST stretch of the journey: from your local post office to your door. The rest of the time it should be in temperature controlled environments.
This means that the day time temperature is the most important to consider. Highs of less than 45-50 degrees F.
The added weight of the heat-pack adds to the total weight of the box.
Always thinking what is best for the plant, one can add a heat pack when really not necessary and the plant can get damaged from too much heat as well. Its a 50/50. But please add one or more depending on how many plants you are getting or how big they are if you live in an area with day time HIGH temps under 45-50. We'll refund you if you get too many or end up not needing one at all.
