The GreenPlanet Liquid Weight is a carbohydrate additive for the flowering stage. It blends simple and complex carbohydrates with amino acids, yucca extract, ascorbic acid, low-molecular-weight humic acid and triacontanol, feeding both the plant and the microbial life in the root zone.
Feeding the root zone as well as the plant
Carbohydrates are an energy source — for the plant directly, and for the microbes living around the roots. An active root zone helps convert nutrients into forms the plant can take up. Humic and fulvic compounds support uptake at the root membrane, and yucca acts as a natural surfactant so the solution wets the medium evenly.
How to use it
Mix 1 mL per litre (4 mL per US gallon) at every watering through the flowering cycle.

FAQ
Liquid Weight or Karbo Boost?
Both supply carbohydrates in flower. Liquid Weight is liquid and adds amino acids, humic acid and yucca. Karbo Boost is a powder — pick one, not both.
Can I use it with Athena Cleanse?
Not recommended. Liquid Weight works partly by feeding root-zone microbes, and Cleanse is an oxidiser built to keep the root zone sterile.
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.
