With tempatures reaching well over the 80's & into the high 100's or with temps getting down below freezing 🥶 we don't want our new plants to show up & be a melted soupy mess or a frozen Popsicle! We make our new purchase & our plants get packaged with care BUT they still have a long journey traveling to us in a small tight hot 🔥 or ❄️ cold📦box! By adding this option it will allow the temperature inside the box to remain slightly cooler or warmer! This is in addition to adding an ice pack or heat pack! which can also be found in the shop! Happy Growing! 💚🤗🪴
