Indoor gardening is a very unique hobby. With this practice, you attempt to create conditions indoors that plants normally need to thrive outdoors. Indoor gardening can be simple as keeping a couple of houseplants, or as complex as a large vertical farm. While technology has made the practice much more approachable for beginners, people still have a good deal of questions about indoor gardening. Of these, Soltech Solutions has received a number of inquires about outdoor conditions affecting indoor gardens. To help our customers feel more confident, Soltech Solutions put together this brief article on planting zones and what they mean for your indoor garden.
What are Planting Zones?Planting zones are regions in the United States and Canada that limit where certain plant species can successfully grow outdoors. Also known as “hardiness zones,” planting zones are separated by temperature intervals of 10 deg F.

The concept of planting zones was originally developed by the USDA and is represented in the Plant Hardiness Zone Map. The USDA created 13 planting zones in the United States and Canada - the coolest being Zone 1 and the warmest being Zone 13.
What Types of Planting Zones are in the USA?Planting zones in the USA are dictated by latitude as well as elevation. Looking at the USDA Plant Hardiness Zone Map, you will largely see a pattern where warmer planting zones exist further south. However, mountainous regions such as Colorado present unique variances in climate, as higher elevations drive cooler temperatures. Examples of planting zones in the USA: Zone 1: coldest zone, minimum temperatures of -60 to -50 deg F.
