Advanced Nutrients Mother Earth Grow 4 Litre - Organic Vegetative Feed
Best for: organic growers who want a complete, plant-derived vegetative feed for soil, coco or hydro without synthetic mineral fertiliser.
Our thoughts
This is Advanced Nutrients' organic Mother Earth range for the vegetative stage — built from plant and mineral extracts rather than lab-made salts. Don't be thrown by the 4 litre size; Advanced Nutrients sell this line in more than one bottle size, and 4 litres is simply a genuine, real option rather than an odd one-off. It's a straightforward organic vegetative feed that does what organic feeds are meant to do: build a healthy plant with the natural inputs a synthetic feed can't offer.
Advanced Nutrients Mother Earth Grow — part of the brand's Mother Earth Super Tea organic range — is a liquid organic supplement designed for the vegetative growth stage. Rather than mineral salts, it's built around plant and mineral-derived nutrients, alfalfa extract, vitamins and beneficial microbial inputs that a synthetic fertiliser simply doesn't contain, aimed at building strong root and foliar growth ahead of flowering.
It's formulated to work across growing methods — soil, coco, rockwool, and recirculating hydro systems, as well as outdoors — and pairs with Mother Earth's flowering-stage counterpart (Mother Earth Super Tea Bloom) when you move the plant into flower. This particular listing is the 4 litre bottle; Advanced Nutrients also produce this line in other sizes, so 4 litres is a genuine, standard option rather than an inconsistency in the range.
How it compares
Mother Earth Grow sits in the established organic vegetative-feed bracket alongside a handful of well-known names.
- Vs Biobizz Bio-Grow: Bio-Grow is a widely used, budget-friendly organic vegetative feed with a broad trace-element profile — Mother Earth Grow competes in the same organic space at a similar functional role, positioned by Advanced Nutrients as a premium organic option.
- Vs Canna Bio Vega: Bio Vega is a concentrated organic vegetative feed popular in EU and UK organic soil grows — both products are aimed at growers who want organic inputs without giving up feed strength.
- Vs General Organics BioThrive Grow: BioThrive Grow uses a vegan plant and mineral-derived formulation with a similar "root, stem and foliage" positioning — Mother Earth Grow occupies comparable ground in Advanced Nutrients' own organic line-up.
If you want to run a fully organic feed programme through vegetative growth rather than switching to synthetic mineral nutrients, Mother Earth Grow gives you an established, purpose-built option rather than a generic substitute.
Usage guidance
As an organic liquid feed, it's used the same way through hand watering or a reservoir dosing routine.
Dosage
Follow the label rate as your starting point — organic teas like this are typically dosed at a low ml-per-litre rate rather than the higher rates used for mineral feeds, and it's worth building up gradually rather than dosing to the top of the range on a first run.
Hand watering
Mix into your water can at feed time and water as normal through the vegetative stage.
Hydro reservoirs
Dose into the reservoir at your regular feed change, keeping an eye on reservoir clarity — organic feeds can be more prone to settling than mineral nutrients.
Switching to flower
Move across to Mother Earth Super Tea Bloom once the plant is flipped to flowering, to match the organic input to the growth stage.

Our take
Mother Earth Grow gives organic growers a proper, purpose-built vegetative feed from a brand with a long track record, built on real plant-derived inputs rather than a marketing spin on a mineral feed. The 4 litre size is simply the practical option for anyone feeding a larger number of plants or running through a full vegetative cycle without reordering halfway through.
A solid choice if you're running an organic programme — proper kit at a price that makes sense for the bottle size you're getting.
