Boost fruit and flower yield.

Start irrigating with an EC of 0.6 – 1.0 mS/cm higher than the EC of the tap water. Do this by filling the nutrition tank with water. Shake Bloom Food well. Add A&B concentrates in equal amounts at the rate of 1.5 – 2.5 ml/L/qt. Add Reiziger Bud Booster at the rate of 0.1 – 0.2 ml/L/qt. Irrigate until drainage appears. Add to nutrition tank from week 1 of bloom until the end of week 3 of bloom.

Without fertiliser program: Mix 1 mL in 1L or 1qt water and spray once a week from the first week of bloom stage until the third week of bloom.

Recommendations. Made simple.

Due to the formula purity and high EC value, it is essential to follow the directions exactly. Bud Booster is commercial grade, super concentrated and therefore inexpensive to use. Do not exceed 0.2 ml/L/qt in combination with fertiliser program otherwise nutrient burn may occur. Apply from the first week of bloom. Never exceed an EC of 1.0 – 1.2 mS/cm higher than the EC of the tap water; this is the total EC including the fertiliser and any boosters.

For big, productive Reiziger Results. Plant it right.

The frequency of feeding depends on the grow room temperature, evaporation and the water supply in the medium. Establishing a balance between the water holding capacity of a medium, aeration and drainage is a key to optimum plant growth. Generally, we recommend giving five-litres/ m²/ day for fully-grown plants.
