Tropic All Mix 50 Litres

Tropic All Mix 50L – Pre-Fertilised Organic Potting Soil

Tropic All Mix 50L is a ready-to-use, pre-fertilised organic potting soil designed to give established plants a rich, balanced growing medium straight from the bag.

The mix combines high-quality peat, perlite, limestone and organic fertilisation to create a root-zone environment with good moisture retention, drainage and aeration. Beneficial microbial ingredients also help support an active growing medium around the roots.

With a pH of 5.5, EC of 1.0 and RHP approval, Tropic All Mix gives you a consistent, nutrient-rich soil at a very competitive price. It's ideal for growers who want an easy-to-use All Mix soil that already contains a useful nutrient charge rather than starting with a lightly fertilised growing medium.

What Is All Mix Soil?

All Mix is a more heavily fertilised type of potting soil designed to provide established plants with nutrition immediately after transplanting.

Unlike a Light Mix, which contains a lighter nutrient charge and gives you more control through bottled nutrients from an early stage, All Mix already contains useful nutrition within the substrate.

This makes it particularly convenient if you want a straightforward soil grow with less feeding required during the early part of the cycle.

Tropic All Mix is designed to provide the rich conditions you'd expect from a fertile outdoor soil while maintaining the consistency, drainage and structure required for indoor growing.

Pre-Fertilised for an Easier Start

One of the biggest advantages of pre-fertilised potting soil is that you don't need to introduce a full-strength nutrient programme immediately after potting up.

The nutrition already present within Tropic All Mix can support plants during their initial period in the fresh substrate, allowing the root system to establish before additional liquid fertiliser becomes necessary.

As a general guide, the initial nutrient charge can support plants for around four weeks, but this shouldn't be treated as a fixed feeding schedule. A smaller plant in a larger pot may use the available nutrition much more slowly than a large, established plant with a developed root system.

Watch how the plants respond and begin supplementary feeding when they actually need it rather than automatically adding nutrients from day one.

Built for a Healthy Root Zone

Good soil needs to hold enough moisture without becoming dense and waterlogged.

Tropic All Mix uses a combination of peat and perlite to create that balance. The peat retains moisture and nutrients around the root zone, while the perlite creates additional air spaces and improves drainage.

This helps maintain oxygen around the roots as the substrate moves through its natural wet and dry cycle.

The mix also contains limestone and beneficial microbial ingredients, helping create the active root-zone environment that soil growers are looking for.

All Mix or Light Mix – Which Should You Choose?

The main difference comes down to how much nutrition you want the growing medium to provide from the start.

Tropic All Mix is the better choice if you want a richer, pre-fertilised soil that can support established plants without immediately adding bottled nutrients.

Tropic Light Mix contains a much lighter nutrient charge, making it better suited to younger plants or growers who want tighter control over feeding from an early stage.

If you're potting up established plants and want the soil to do more of the feeding for you, All Mix is the one we'd choose.

Pair Tropic All Mix with a Quality Soil Nutrient

Tropic All Mix already contains a useful nutrient charge, so there's no need to start adding a heavy feed immediately after potting up.

Once the nutrition in the media begins to run down, we'd pair it with a trusted soil-specific nutrient programme such as the Shogun Fertilisers Full Soil Nutrient Kit.

The Shogun kit is built around Samurai Terra and gives you a complete soil feeding programme for the full growing cycle, making it a strong match for Tropic All Mix once the initial nutrient charge starts to fade.

Start feeding according to plant demand rather than simply following the number of weeks since potting up.

How to Use Tropic All Mix

1. Loosen the soil: Break up any compressed sections before filling your pots.
2. Fill your containers: Add the soil without packing it down heavily so the structure stays open and aerated.
3. Pot up established plants: Tropic All Mix is nutrient-rich, so it's particularly well suited to established plants rather than very young seedlings.
4. Water thoroughly: Give the substrate an even watering and allow excess water to drain freely.
5. Allow wet and dry cycles: Avoid keeping the soil constantly saturated. Allowing some drying between waterings helps fresh oxygen return to the root zone.
6. Don't overfeed early: Remember that the substrate already contains fertiliser.
7. Introduce nutrients when required: Begin supplementary feeding once plant demand starts to exceed the nutrition available in the soil.

Our Take

If you want an easy pre-fertilised soil without paying premium-brand prices, Tropic All Mix is one of the strongest-value options in the Tropic range.

You can pot established plants straight into it and let the media do much of the work early on rather than immediately introducing a full bottled feeding programme.

It's also noticeably different from Tropic Light Mix. We'd use Light Mix where we want maximum control over feeding from an early stage, whereas All Mix is what we'd reach for when we want a richer soil that already has some food in it.

For straightforward soil growing, particularly when you're filling several pots and media costs start adding up, Tropic gives you a lot of growing medium for the money.

Top Tip: Don't treat All Mix like an unfertilised potting soil. There's already food in the substrate, so adding a heavy nutrient feed immediately after transplanting can be counterproductive. Let the existing nutrient charge do its job first, then introduce a quality soil feed such as the Shogun Fertilisers Full Soil Nutrient Kit as the plants begin to require more nutrition.
