The GreenPlanet Karbo Boost is a powdered carbohydrate additive for the flowering stage. It supplies a clean, readily available energy source that feeds beneficial microbes in the root zone, supporting nutrient uptake and flower development. It's pH neutral and works with any nutrient schedule.
Energy for the root zone
Carbohydrates feed the beneficial microbes living around the roots. An active microbial population breaks nutrients down into forms plants can absorb, which supports uptake and overall vigour through flower.
How to use it
Dissolve 30 g in 100 litres of water (0.3 g per litre) and use with every watering through the flowering cycle. It suits soil, coco and hydro.

FAQ
Karbo Boost or Liquid Weight?
Both supply carbohydrates in flower. Karbo Boost is a powder; Liquid Weight is liquid with added amino acids and humic acid. Choose one.
Can I use it with sterilising products?
Not recommended. It works by feeding microbes, which oxidisers like Athena Cleanse are designed to remove.
Can I mix it with another brand?
We don't recommend it. GreenPlanet's feed programs are built around its own bases and additives, so results are most predictable when you stay within the range.
