Reiziger

A short premium range

Reiziger runs five products, and prices them at the top of the market — the 10L Root Booster is among the most expensive single bottles on this store. The argument for that pricing is concentration and consistency; whether it holds for your garden is worth testing at 300mL before committing to litres.

The boosters

Root Booster. The flagship, in 300mL, 1L, 5L and 10L. Aimed at 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, working alongside Bud Booster rather than instead of it.

Base nutrient

Coco Food A+B in 1L is the range's complete nutrient for coco coir — a two-part formulation accounting for the way coco binds calcium and magnesium. It is the only base nutrient Reiziger stocks here, so growers on other substrates use the boosters alongside another brand's base. More coco-specific options are 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 point, trialling before scaling is simply sensible.
2. Concentrates are dosed lightly. Premium boosters are not measured by the capful. Follow the label rate and resist the temptation to add more.
3. Match the base to your medium. Coco Food A+B is coco-specific. On other substrates, pair the boosters with a base formulated for what you are growing in.
4. Measure the result. Boosters raise feed strength. Check the finished solution with an

Check the finished solution with an EC meter before it goes near the plants.
