Grotek Solo-Tek Bloom

Grotek Solo-Tek Bloom: generous flowering from a single bottle

Once plants switch to flowering, their needs change completely: less nitrogen, far more phosphorus and potassium to build and fill out the flowers. Solo-Tek Bloom is Grotek’s answer: a highly concentrated one-part bloom base that delivers exactly that balance, week after week, right up to the flush.

A formula built for flowering

• NPK 3-8-8: low nitrogen, with equal phosphorus and potassium, the two key elements for bulking and ripening flowers.
• Calcium and magnesium for strong tissue and efficient photosynthesis to the very end.
• Trace elements: sulphur, iron, manganese and molybdenum.
• Kelp extract, a natural ingredient that complements the mineral formula.

Specifications

The Grotek bloom programme

Solo-Tek Bloom takes over from Grotek Solo-Tek Grow when flowering starts. To go further, add the PK booster Grotek Monster Bloom as the buds form, and Grotek Vitamax Plus for vitamins. Browse the full range in our Grotek nutrients category.

FAQ

Solo-Tek Bloom or Impact Bloom A+B?

Both are Grotek bloom base nutrients. Solo-Tek Bloom comes in a single bottle and is easier to dose; Impact Bloom is a two-part formula designed for automated irrigation systems.

Do I need to add a booster?

Not necessarily: Solo-Tek Bloom is a complete base nutrient. Boosters help you get more out of the flowering phase.

When should I stop using Solo-Tek Bloom?

About 15 days before harvest. After that, water with plain water until the end.
