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.

What problem does ONA Gel solve for growers?
ONA Gel is engineered to tackle persistent and strong odours, offering a comprehensive solution for cultivators. It effectively neutralises unwanted scents at their source, rather than masking them, ensuring a cleaner and more pleasant growing environment. This odour neutralisation is critical across all stages, from seedling to harvest, and is compatible with a universal range of growing media, including soil, coco, and hydroponic systems. For instance, ONA Gel PRO actively neutralises strong household odours and its effectiveness is demonstrated across its product range.

Which ONA Gel scent is right for your grow space?
The ONA Gel collection offers a variety of scents to suit different preferences and environments. For a fresh, clean aroma, consider ONA Gel Fresh Linen, available in 500 ml, 1 l, and 4 l sizes. If you prefer a more tropical fragrance, the ONA Gel Tropics in 500 ml, 1 l, and 4 l options provides a powerful neutralisation. For a sweet, dessert-like scent, ONA Gel Apple Crumble is available in 500 ml, 1 l, and 4 l formats. The zesty ONA Gel Lemon Grass comes in 500 ml, 1 l, and 4 l sizes, while the clean and crisp ONA Gel Polar Crystal offers 500 ml, 1 l, and 4 l capacities. For growers seeking an uncompromised odour elimination, the specialised ONA Gel PRO is available in 500 ml, 1 l, and 4 l, designed to actively neutralise even the most stubborn odours. Explore complementary products like ONA Spray for immediate odour control, or ONA Příslušenství for application aids. For larger-scale odour management, consider ONA Block or ONA Liquid solutions.
Understanding ONA Gel vs. alternatives
When compared to generic air fresheners or masking agents, ONA Gel stands out due to its scientifically formulated neutralisation technology. Unlike products that simply cover up smells, ONA Gel targets and permanently eliminates odour molecules. This makes it a superior choice for growers who require a truly fresh environment without any lingering scents. While other brands may offer temporary relief, ONA Gel provides a lasting solution grounded in its natural, non-toxic formulation. It’s the professional standard for odour control in sensitive grow environments.
Making the choice for effective odour control
Growers dealing with strong vegetative or flowering smells often start with a smaller ONA Gel Apple Crumble 500 ml or ONA Gel Lemon Grass 500 ml to test effectiveness. For larger tents or rooms, scaling up to a 4 l option like ONA Gel Fresh Linen 4 l or ONA Gel Fruit Fusion 4 l is a common strategy. If standard scents are insufficient, growers demanding the highest level of odour elimination select the specialised ONA Gel PRO 4 l. For immediate, targeted odour bursts, ONA Spray is the go-to, whereas for continuous, passive release in enclosed spaces, ONA Block products are often preferred over gels.

Which ONA Gel size is best for a small grow tent?
For smaller spaces like a grow tent, a 500 ml or 1 litre size such as ONA Gel Apple Crumble 500 ml or ONA Gel Lemon Grass 1 L is typically sufficient for effective odour control.
Can ONA Gel be used in hydroponic systems?
While ONA Gel is primarily for ambient air odour control and not directly added to nutrient solutions, its effectiveness complements all growing media and systems, including hydroponics, by neutralising airborne odours.
