The Grow Queen Soil Differentiation You Didn't Know You Needed : When to use which potting mix.
Wrong soil is one of the most common reasons a houseplant struggles, and it usually comes down to putting a plant in the wrong bag.
We currently produce two Craft Potting Mixes, and the question we get most is which one a plant actually needs. Every ingredient in both is the same natural and organic compounds, chosen because it mimics the forest floor that a plant would actually root into in the wild, never a synthetic stand-in for it. The ingredients in both bags are almost entirely the same, . It is the ratio of those ingredients that changes everything. It is not about which mix is "better." It comes down to how that specific plant grows in the wild, how much drainage its roots expect, and how forgiving you need your watering schedule to be. Here is the real difference between the two bags, and exactly why its not black and white what belongs in which one.
The Real Difference Between the Two Bags
Both mixes are peat-free, synthetic-free, and built to feed the soil biology that feeds the plant. Where they split is texture and drainage speed, because different roots want different things.
Drainage speed
Aroid Mix is built to drain fast and dry out quickly. Houseplant Mix holds a good, even amount of moisture for longer.
Texture
Aroid Mix is chunky, with large bark and fiber pieces built for airflow. Houseplant Mix is more refined and fine, built to hold water without going dense.
What it is built to mimic
Aroid Mix mimics bark and leaf litter, the environment epiphytic plants root into in the wild. Houseplant Mix mimics general, moisture-retentive tropical soil.
Margin for error
Aroid Mix is rejects overwatering by design, that is the point. But you must pair it with good airflow and steady moisture. The Houseplant Mix is the more forgiving option holding onto hydration longer, and needing less attention.
Craft Aroid Potting Mix: The Drainage Specialist
This is our highly chunky mix, a living soil built for plants that grow as "aroid" or air bound in the wild, rooting into bark and leaf litter high off the forest floor rather than dense earth. It leans heavier on fir bark, pumice, lava rock and tree fern fiber than our Houseplant Mix does, so their roots expect huge amounts of airflow and very little standing moisture. This mix is formulated to reduce the risk of overwatering, while remaining porous and protects large root systems from rot, giving room to breathe. Every ingredient is thoughtfully sourced with sustainability in mind, and is a hand selected mix of tropical plants favorite minerals.
What's inside: (From highest to lowest percentage): Pumice, lava rock, premium fir bark, worm castings, New Zealand tree fern fibers, biochar, organic coco coir, alfalfa meal, and gypsum.
Use Aroid Mix for:
- Monstera
- Philodendron
- Alocasia
- Anthurium
- Any other tropical plant that needs excellent drainage
Craft Houseplant Potting Mix: The Generalist
This is our higher-density mix, a living soil built with worm castings, biochar, lava rock, pumice, and coco fiber, leaning heavier on the ingredients that hold moisture. It is formulated to hydrate evenly through the root zone and hold its texture over months of watering, so it never collapses into mud. Gnat-resistant aeration ingredients keep pore space open even with that extra moisture retention, and it comes nutrient-rich from day one, so a freshly repotted plant can settle in without needing to be fed right away. It is less chunky than our Aroid Mix, refined for the plants that want steady hydration alongside good airflow, forgiving whether you tend to underwater or overwater.
What's inside: (From highest to lowest percentage) Worm castings, triple washed coconut coir, fir bark, pumice, lava rock, gypsum, alfalfa meal, and biochar.
Use Houseplant Mix for:
- Ferns
- Peace lilies
- Tradescantia
- Cane Begonias
- Most flowering houseplants
How to Choose
Ask yourself: does this plant grow as an climber in the wild?
If it climbs and roots onto a tree, like a Monstera or Philodendron reach for the Aroid Mix.
Is it a general tropical or flowering houseplant?
Ferns, peace lilies, ficus, and most everything else found in your local walmart to place on a windowsill will do just fine in the Houseplant Mix. They need the hydration, and our organic mix provides that and more with benefitial microbes, unlike standard potting soils.
Not sure, stick with the houseplant mix?
When in doubt, more drainage is safer than less, and our houseplant mix is truly like no other. These mixes both provide dense nutrition while providing unmatched aeration. Overwatering is still the number one cause of houseplant loss, so if a plant is anywhere close to an aroid territory... the chunkier Aroid mix is the safer bet.
What Is Actually Making the Difference
Both mixes share the same core, premium fir tree bark, as a byproduct of the lumber industry, pumice over perlite as a porous rock base that doesn't break down, 100% organic worm castings for nutrition and added benefitial microbes, bio activated charcoal as a stimulant, gypsum, and alfalfa meal to feed, all while being peat, soil, and perlite-free.
The split comes down to one ingredient, and the difference in ratio. Aroid Mix adds tree fern fiber, a fibrous, almost moisture-free material that exists purely for airflow, to help stabilize the soil helping lock in roots. The Houseplant Mix tops off with more worm castings, holding moisture loonger, and the Aroid Mix builds deep with an elite chunky structure, prioritizing the lava rock and pumice side of the mix.
The right soil is not an accessory. It is the foundation everything else depends on.
