8. Orchid Potting Bark
Although orchids can be beautiful, they can be a bit difficult to grow, to say the least. And if you want to grow healthy orchids, you’ll need an orchid potting mixture for the task. Since orchids are a popular choice for indoor house plants, we decided to include this mix in our review.
This orchid mix is a tad smaller than other mixes, but just as good. The bark chips are small enough to fit around the roots of your orchid and into your pot. This orchid bark is made from organic, sustainable bark taken from healthy Douglas fir trees. And though it’s absorbent, it allows for plenty of oxygen to reach orchid roots.

9. Hoffman Seed Starter Mix
This blend by Hoffman contains Canadian sphagnum moss which is more sustainable than peat moss from other sources. Note that this mix is best for seeds only, and you will need to transfer your plans to another soil mixture as they sprout.
So, if you’re new to indoor plants and you need a great soil mix for germination, here is one to consider. The mixture is light and retains moisture well, making it the best potting soil to start seeds. The mixture also contains vermiculite, which is a soil amendment that helps with moisture retention. It simply expands upon contact with water to help the soil stay moist longer.
