Grotek Solo Tek Bloom


Grotek Solo-Tek Bloom provides optimum nutrient ratios for prolific flowering and fruiting. Highly effective as a stand-alone fertilizer


Grotek Solo Tek Bloom
Grotek Solo-Tek Bloom is a one-part base nutrient that is easy-to-use and highly effective on a range of crops. This concentrated formula was specifically designed to benefit both soil and soilless growing environments, where cation exchange occurs.  In a water-based system, the benefit of a common 3-part nutrient is an immediate change in nutrient ratios, giving growers fast reaction to the plant’s needs. However, in media like peat or coco coir, this benefit doesn’t have the same impact as nutrients move and bind in the soil or soilless structure, delaying interaction with plant roots.  Solo-tek Grow and Bloom were designed to counteract this, ensuring plants receive the nutrients they need, when they need it.

The proprietary Solo-Tek formulations are extremely concentrated and require low application rates. High levels of humic acid ensure increased nutrient availability, and can also support beneficial biology in the soil.

The nutrient profile in Solo-Tek Bloom supports flower development and growth, while improving yield. High levels of calcium support strong plant structure and heavy development. Added micronutrients support higher yield, and improved crop quality.

How to Use:
  • Application Rate: 1L makes 500L of solution.
  • Begin use 7-10 days before blooming.
  • Fertilizer with Supplements – Soil/Soilless/Water Culture:  Use in conjunction with your regular fertilizer program to boost  flower production.
  • Early Flowering: Mix ½ tsp per 1.25 qt of water (2 ml per 1 L) Use as needed. Late Flowering: Mix ¾ tsp per 1.25 qt of water (3 ml per 1 L).  Use as needed.
  • Fertilizer – Stand Alone – Soil/Soilless/Water Culture: Mix ¾−1 tsp per 1.25 qt of water (3−4 ml per 1 L). Use every time you fertilize.

As a suspension, this formula requires sufficient agitation prior to use. Each bottle of Solo-tek contains pure nutrients and has no added water.  With this in mind, be sure to re-suspend nutrients prior to use to ensure top results.  Specific gravity is so high that it can’t be sold in a 23L as the bottle’s handle will break… that means a lot of nutrients and explosive plant growth in every bottle!
