Tropic Light Mix 50 Litres - Lightly Fertilised Soil for Full Feed Control
Best for: Growers who want a ready-to-use organic soil but prefer to control nutrient feeding themselves from an early stage, and anyone starting cuttings or seedlings.
Our thoughts
This is the soil we'd point new growers toward if they want to actually learn to feed their plants rather than relying on a heavily pre-charged mix to do it for them. It's got enough organic nutrition to get young plants going without swamping them, and because the charge is light, you're in control of what happens next.
Tropic Light Mix is a ready-to-use, lightly fertilised soil substrate built on a peat and perlite base with added limestone for pH stability and beneficial microorganisms for root zone health. Unlike Tropic All Mix, it carries a much lower organic nutrient charge, giving plants enough to establish without overwhelming young or sensitive root systems, while leaving you in control of feeding as growth ramps up.
How it compares
Positioned as the lower-nutrient-charge option in a category with well-known European equivalents.
- Comparable in concept to BioBizz's Light-Mix, the product that established this "lightly fed" soil category as a companion to heavier all-in-one mixes.
- Versus Tropic All Mix (its heavier-fed sibling), Light Mix carries a much lower starting nutrient charge, meaning feeding needs to start sooner but with far more control over the exact ratio and timing.
- Versus straight peat or coco with no fertiliser at all, Light Mix still gives young plants a gentle nutrient base at the start, rather than requiring feed from the very first watering.
Less initial nutrition than All Mix, but more control - suited to growers who'd rather set their own feed schedule than rely on the soil's built-in charge.
Usage guidance
Cuttings and seedlings
Ideal for potting up cuttings and seedlings, where a heavily charged soil could risk nutrient burn on delicate young roots - the light charge here reduces that risk.
Starting to feed
Begin introducing a light nutrient feed earlier than you would with All Mix, typically once true leaves are established, since the built-in charge is lower and depletes sooner.
Repotting
Works well as a transitional medium when repotting young plants up from smaller starter pots before moving into a heavier-fed soil or larger containers.
Watering
Water thoroughly and let the surface dry slightly between waterings - the peat/perlite base drains a little more freely than a straight peat mix.
Technical specifications

- Bag volume: 50 Litres
- Additional features: Beneficial microorganisms included
- Format: Ready to use, no mixing required
Who this is for
- Growers potting up cuttings or seedlings who want to avoid nutrient burn on young roots
- Growers who want to control their own feed schedule rather than rely on a heavy pre-charge
- Anyone repotting young plants before a final move into larger containers
- New growers wanting to learn to read and adjust feeding as they go
Best suited to the early stages of a grow, or to growers who prefer hands-on control over feeding throughout.
Our take
Light Mix is the right call if you want a soil that gets plants established without doing all the feeding decisions for you - it's a gentler starting point than All Mix and gives you room to build up your own feed programme. Good value against comparable lightly-fed soils from bigger-name brands.
One we sell a lot of for new growers who want to learn proper feeding from the ground up. Worth picking up for cuttings and seedlings especially.
