HolidayGrow by Dryferm – Hydrogel Water & Nutrient Storage for Plants
HolidayGrow by Dryferm is a modern water and nutrient storage solution for plants, developed to make watering in cultivation significantly safer, simpler, and more efficient. The hydrogel stores excess water and dissolved nutrients directly in the substrate and then releases them evenly to the roots when the plant needs them.
This results in longer watering intervals, more stable moisture in the pot, and less stress from dry periods or inconsistent watering. According to the published product information, HolidayGrow is particularly interesting for beginners, busy growers, and for times when plants cannot be watered daily, such as during holidays or extended absences.
Hydrogel for long watering intervals and strong roots
The potassium polyacrylate hydrogel contained in HolidayGrow acts as an intelligent buffer in the substrate. It helps balance over- and underwatering, keeps water in the root area longer, and makes nutrients available instead of flushing them out too quickly.
Thus, HolidayGrow supports more uniform growth, stronger roots, and overall more stable plant development. The official product specifications explicitly describe HolidayGrow as a solution for long watering intervals, stable moisture, and strong root formation.
Suitable for soil, coco, and living soil
HolidayGrow is suitable for various substrates and can be used in soil, coco, living soil, and mixed substrates. Additionally, the product is compatible with organic and mineral fertilizers, allowing for flexible use in different grow setups.
Especially in living soil setups, consistent moisture is particularly important because it supports active soil life and maintains more constant conditions in the root zone. The product texts for HolidayGrow also emphasize that water and nutrient storage, root development, and soil life are intended to be supported together.
Overview of HolidayGrow's benefits
- Hydrogel water and nutrient storage for plants
- Significantly extends watering intervals
- Helps with over- and underwatering
- Supports strong roots and more uniform growth
- Suitable for soil, coco, living soil, and mixed substrates

Biodegradable and responsibly developed
HolidayGrow is described by Dryferm as biodegradable and classified as a safe solution for use in substrates. Supplementary dealer and accompanying information indicates that the material acts as a water gel in the root area during use and is controlledly broken down over a longer period.
Thus, HolidayGrow combines modern grow accessories with practical everyday benefits: less watering stress, more control over moisture, and a more reliable supply of water and nutrients to the plant. This makes the product an interesting solution for indoor growers, home growers, and anyone looking to make their substrate irrigation more efficient.

HolidayGrow – The end of watering stress
Why do so many plants fail due to watering?
Too much water leads to waterlogging and root rot, while too little water causes drought stress and stunted growth. At the same time, valuable nutrients are often simply washed away.
This is precisely the biggest problem for many growers – and this is exactly where HolidayGrow comes in.
for a complex problem
HolidayGrow stores excess water and nutrients in the substrate and releases them evenly to the plants. The roots grow directly into the gel and supply themselves – precisely as needed.
Frequently Asked Questions
Quite the opposite – HolidayGrow was specifically developed to promote soil life. It creates a consistently moist environment that supports microorganisms and root growth. Feel free to watch the video from Garten Eden to learn more about its effects.
Not entirely. Your plants' water needs change with their growth.
- During the vegetative phase, young plants, cuttings, or seedlings require less water.
- During the flowering phase, consumption increases significantly.
Therefore, the gel noticeably extends watering intervals in the first few weeks, but they shorten again in later phases. Towards the end of our test, we only had to water every 5–7 days – an enormous help despite increasing water demand.
