House & Garden Bio - 1 Part Aarde 1 Litre - Organic-Mineral Soil Feed, One Bottle
Best for: soil growers who want a single-bottle feed with more of an organic, living-soil character than a straight mineral formula.
Our thoughts
Don't be fooled by the "Bio" name into thinking this is certified organic, it's not, and House & Garden don't claim it is. What it actually is: a well-regarded hybrid feed that leans organic in character while keeping mineral precision, in a single bottle. If you like the idea of feeding your soil's biology as well as your plant, this is the H&G option to reach for over the standard Aarde.
House & Garden Bio - 1 Part Aarde is a one-part base nutrient for soil cultivation that blends organic inputs with mineral nutrition in a single bottle used through both the vegetative and flowering stages. It's the more organic-leaning sibling to House & Garden's standard 1-Component Aarde, aimed at growers who want to feed the soil's micro-life as well as the plant.
The formula includes humic acid, fulvic acid and chelated iron for improved nutrient uptake, and is built to support soil health alongside plant growth rather than just delivering raw NPK. It's not accredited by any organic certification body, since it still contains mineral components, but it's widely regarded among UK hydroponics retailers as one of the stronger soil feeds in its category.
How it compares
Bio Aarde occupies the organic-mineral middle ground between straight mineral feeds and fully organic lines.
- Versus House & Garden's standard 1-Component Aarde: this Bio version adds an organic character and more emphasis on soil biology, while standard Aarde is purely mineral.
- Versus BioBizz's organic soil range: BioBizz is positioned as genuinely organic-certified in places, while Bio Aarde sits closer to a hybrid, not fully organic-accredited.
- Versus CANNA Bio range: CANNA's organic line uses plant-based inputs throughout, whereas Bio Aarde keeps some mineral backbone for consistency.
It's a good middle path if you want an organic feel without giving up the predictability of mineral nutrition.
Usage guidance
Used the same way as most House & Garden one-part feeds, in a single bottle throughout the grow.
Dosage
Apply as directed on the bottle, scaling up as the plant matures; there's no need to change products between veg and flower.
Feeding method
Suitable for hand-watering or drip-fed soil systems, mixed directly into your reservoir or watering can.
Pairing
Works alongside the rest of the House & Garden additive range, including Roots Excelurator and the Top Booster/Top Shooter bloom boosters, if you want to push performance further.

Our take
This is a genuinely different product to House & Garden's standard Aarde, not a duplicate, so don't assume they're interchangeable. If the organic angle matters to you, Bio Aarde is the one to pick.
Straightforward, well-regarded feeding at a price that makes sense.
