Reiziger

A short range at a premium price

Reiziger is five products, priced at the top of the market — the 10L Root Booster sits among the dearest single bottles on this store. Concentration and consistency are the case for that price; whether they hold in your garden is worth proving at 300mL before you move up to litres.

The boosters

Root Booster. The flagship, in 300mL, 1L, 5L and 10L. Written for root growth and plant development from establishment onwards.

Grow Booster. The vegetative enhancer, in 1L, 5L and 10L.

Bud Booster. The flowering enhancer, in 300mL.

Bloom Minerals. A flowering booster and yield enhancer in 300mL, meant to sit alongside Bud Booster rather than replace it.

Base nutrient

Coco Food A+B in 1L is the complete two-part nutrient Reiziger writes for coco coir, built around the way coco binds calcium and magnesium. It is the only base they stock here, so growers on other substrates run the boosters with another brand's base. More coco-specific options sit in Coco Nutrients.

Buying into a premium range

1. Start at 300mL. Root Booster, Bud Booster and Bloom Minerals all come in 300mL. At this price, a trial bottle before the litres is simply sensible.
2. Dose concentrates lightly. Premium boosters are not measured by the capful. Follow the label rate and do not add extra.
3. Match the base to your medium. Coco Food A+B is coco-specific. On other substrates, pair the boosters with a base written for what you are growing in.
4. Measure the result. Boosters lift feed strength. Check the finished solution with an EC meter before it goes near the plants.
