Advanced Nutrients CarboLoad - Liquid Carbohydrate Feed for Bigger Yields
Best for: growers who want to feed extra energy to their plants and root-zone microbes across the whole grow, not just the finishing weeks.
Our thoughts
CarboLoad is a simple idea done well - plants and the beneficial microbes around their roots both use carbohydrates for energy, and this tops that supply up on demand rather than leaving it to whatever the plant produces itself. It's an easy one to add to a feed schedule because there's no complicated timing to get right, just consistent use across the grow.
CarboLoad is a liquid carbohydrate supplement, providing a source of simple and complex sugars that plants and root-zone microbes can use directly for energy, rather than the plant having to produce all of its own carbohydrates through photosynthesis alone. It's designed to be used from rooted cutting right through to the last week before your pre-harvest flush.
Advanced Nutrients' own dosing guidance has varied slightly between reformulations of this product - most current guidance points to a low rate of around 2ml per litre, but it's worth checking the mixing instructions on your specific bottle since rates have shifted over the years.
How it compares
CarboLoad sits in the carbohydrate-feed category alongside a few well-known names.
- Compared with Canna Boost Accelerator, which combines carbohydrates with a broader range of growth-boosting compounds, CarboLoad is a more focused, straight carbohydrate feed.
- Compared with Botanicare Sweet, a similarly focused carb supplement, CarboLoad covers a comparable role and is dosed in a similar way.
- Compared with an enzyme-based product like House & Garden Multi Zyme, which works on breaking down dead root matter rather than feeding energy directly, CarboLoad serves a different purpose and the two are often used together rather than as alternatives.
It's a straightforward, no-frills carbohydrate additive rather than a multi-function product, which keeps it simple to dose alongside whatever else you're running.
Usage guidance
Designed to be used consistently rather than at a specific single stage.
Dosing
Check the mixing ratio on your bottle - current guidance is generally around 2ml per litre, added to your feed water.
Timing
Use from rooted cutting or seedling stage right through to the last week before your pre-harvest flush.
Mixing
Add alongside your base nutrients and any other bloom additives - it doesn't need to be dosed separately from the rest of your feed.

Who this is for
- Growers wanting to support both plant energy and root-zone microbial activity across the full grow
- Anyone running a beneficial-microbe product like a root inoculant, since carbs help feed those microbes too
- Growers looking for a simple, single-purpose additive rather than a multi-function blend
Our take
CarboLoad does one job and does it consistently - it's not flashy, but a steady carbohydrate supply across the grow is genuinely useful, especially if you're also running beneficial microbes that need feeding too.
Does exactly what it should, day in, day out - a sensible, low-fuss addition to most feed schedules.
