About us. Our 9 year history

GoToGarden started in 2017 out of personal frustration. Our founder was a hobby grower who spent hours navigating online shops that felt built by people who had never touched a plant — cluttered layouts, vague product descriptions, no real guidance on what to actually buy or why. He knew there had to be a better way.

Why do my plants look unhealthy during growth and bloom?

Hesi nutrients are formulated to address common issues like poor nutrient uptake, weak root systems, and suboptimal flowering, ensuring your plants receive precisely what they need at every stage. Specific formulations tackle deficiencies that can lead to stunted growth and reduced yields, providing essential elements like nitrogen, phosphorus, and potassium, alongside vital vitamins and amino acids. These products aim to fortify plant resilience and promote vigorous development from seedling to harvest.

What Hesi nutrients and supplements are available for different grow setups?

The Hesi range offers comprehensive feeding solutions for various cultivation methods. For hydroponic systems, explore Hesi Hydro Growth 1 l and Hesi Hydro Bloom 5 l, designed to work with hydroponic setups. For coco coir growers, the Hesi Coco 10 l provides a single-bottle solution for both growth and bloom phases, complemented by specific products like Hesi Coco 20 l. Soil growers can utilize general base nutrients and specialized supplements. Beginners can start with comprehensive kits like the Hesi Starterbox Hydro 3.51 l, sada hnojiv, the Hesi Starterbox Soil 3.51 l, sada hnojiv, or the Hesi Starterbox Coco 3.51 l, sada hnojiv. Specialized products such as Hesi OrchiVit 10 l na orchideje cater to specific plant needs, while Hesi PowerZyme 1 l and its larger variants like Hesi PowerZyme 10 l enhance nutrient absorption and root health across all media. Other essential supplements include Hesi Boost 1 l, Hesi SuperVit 100 ml, and Hesi ClonFix 100 ml for rooting cuttings. Explore the full spectrum from Hesi - základní hnojiva to specialized Hesi BIO lines and Hesi - doplňky.

How does Hesi compare to other nutrient brands for advanced growers?

Hesi distinguishes itself by offering a balanced approach that integrates essential vitamins and amino acids into its formulations, supporting plant metabolism and resilience beyond basic NPK ratios. While some brands focus solely on high NPK values, Hesi emphasizes a holistic feeding strategy designed to promote vibrant growth and robust flowering. This is particularly evident in their inclusion of specific compounds that aid nutrient absorption and contribute to overall plant health, making it a strong choice for cultivators seeking to optimize plant vitality and yield.

When should I use Hesi base nutrients versus flowering boosters?

For plants in the vegetative stage, beginning with a foundational growth nutrient like Hesi TNT Complex 500 ml or Hesi TNT Complex 1 l is recommended to build a strong structure. As plants transition into flowering, introducing a bloom-specific nutrient such as Hesi Bloom Complex 500 ml or Hesi Bloom Complex 1 l becomes crucial. For an extra boost during the critical flowering phase, supplements like Hesi Phosphor Plus 5 l or Hesi PK 13/14 500 ml can be used in conjunction with base bloom nutrients to intensify flower development and density. For hydroponic systems, specific hydro formulations like Hesi Hydro Growth 1 l for vegetation and Hesi Hydro Bloom 5 l for flowering are advised. For soil and coco, combining TNT Complex with Bloom Complex and boosters ensures a complete feeding program.
