Description

Hesi Boost – targeted support for flowering and fruit ripening

Hesi Boost is a liquid flowering additive for soil, coco and hydroponic growing. Used alongside your base nutrient, this flowering accelerator supports the transition into bloom and subsequent flower development. It suits beginners and experienced growers looking to supplement their existing feeding programme.

Ingredients: an organic base with added PK

The formula contains plant and fruit extracts with natural sugars, minerals, enzymes and fruit acids. Phosphorus and potassium supplement this organic base, with a stated PK value of 1-1. Boost is a supplementary bloom booster, not a replacement for a complete base nutrient.

When and how often to use Hesi Boost

Start with a single application towards the end of vegetative growth as plants move into flowering. Regular applications follow during bloom, for example once or twice a week. Use the Hesi feeding schedule for your growing medium to determine the relevant application weeks.

Dosage for watering and foliar feeding

For watering, add 2 ml per litre of water, equivalent to 20 ml per 10 litres. For foliar feeding, use 1–2 ml per litre of water. Spray the green parts of the plant evenly, avoiding the flowers wherever possible.

Pair with a base nutrient for your growing medium

For the main feed in soil, combine Boost with Hesi Bloom Complex. Choose Hesi Coco for coco substrates or Hesi Hydro Bloom for hydroponics. This keeps your base nutrition matched to your growing medium.
