HolidayGrow in Substrates FAQIn this FAQ, we answer the most common questions about HolidayGrow, microplastic accusations, and its safe application in the root zone. You will learn the difference between potassium and sodium hydrogels, how the water gel works in the soil, and why it is not hard microplastic. Clearly explained, practical, and transparent – for everyone who values stable soil moisture, healthy plants, and responsible substrate solutions.

HolidayGrow solves one of the biggest problems in plant cultivation: proper watering. The innovative hydrogel, based on potassium polyacrylate, stores water and nutrients at a ratio of up to 1:500 and releases them to the roots as needed. Waterlogging, drought stress, and nutrient leaching are effectively reduced. Enriched with mycorrhizae for strong root growth, silicon for robust cell structures, and calcium-magnesium (CalMag) for indoor growing, HolidayGrow is specifically designed for cannabis cultivation. It is non-toxic, heavy metal-free, biodegradable, and suitable for all substrates – especially living soil. Less watering, less fertilizer, stable moisture in the pot, and healthy soil life – HolidayGrow is the well-thought-out complete solution for modern water management.

Sometimes, a groundbreaking method doesn't arise from planning, but from a genuine problem. When a male plant needed isolation, a Dryferm Bag was simply pulled over it – with surprising results: The microclimate remained stable for two weeks, without moisture damage or mold. The fine pollen could be collected dry, clean, and in a controlled manner. What was once risky or impossible suddenly became reliable. This is precisely where the Dryferm Bag proves to be much more than just a drying bag – it is a precise tool for modern growers.

Dryferm Bag – maximum quality directly after harvestThe Dryferm Bag preserves flowers immediately after harvest and protects exactly what would otherwise be lost: terpenes, aroma, and active ingredients. Just like flash-freezing food, the valuable plant compounds are stabilized before oxygen and time can degrade them. The result is a more intense flavor, a clearer strain profile, and noticeably better flowers – without long air drying, without unnecessary loss of quality. Dryferm preserves what you have grown.

Before Dryferm, drying was greatly underestimated, even though it's the final step that determines success or failure. It was only through Sanlight's scientific approach that it became clear that the old 60/60 rule from the USA is not optimal. At 60% humidity, fermentation processes occur that damage terpenes and ingredients. The crucial factor is the aw-value, which must be brought below 0.8 as quickly as possible to prevent mold and quality loss. We'll show you how to do it right without broscience.
