Description
Crazy Hills Upthrive Grow 5 Litre is a professional vegetative base nutrient from Crazy Hills’ new UK-focused growing range, formulated to deliver balanced, complete nutrition for plants in their vegetative development phase across all growing media types. Upthrive Grow provides the nitrogen-forward nutritional profile that actively growing plants need to develop the robust canopy, dense root system, and strong structural framework that underpins productive flowering performance later in the growing cycle.
The Crazy Hills Growing Philosophy
Crazy Hills has entered the UK nutrient market with a focus on professional performance, accessible pricing, and formulations that have been developed with the specific challenges of UK growing conditions in mind. Upthrive Grow is the vegetative foundation of their two-part Grow and Bloom system. It contains all essential macro and micronutrients in a chemically stable formulation that remains consistent across a wide range of temperatures and storage conditions. The nitrogen profile in Upthrive Grow combines nitrate and ammoniacal nitrogen to support rapid, even vegetative growth. Nitrate-nitrogen provides fast, directly available plant nutrition. Ammoniacal nitrogen is converted by soil and coco microbes over time, providing a sustained background nitrogen supply that smooths out the peaks and troughs of uptake that can occur with single-form nitrogen sources. This balanced nitrogen approach produces consistent, even vegetative development with deep green foliage and compact internodal spacing. We stock the Crazy Hills range at The Horticulture Company and have been impressed by the performance data from our first customers using the system. It represents strong value for money in the UK nutrient market.
Dosage, pH Targets, and Compatibility
Upthrive Grow is used at the recommended dose per litre of water throughout the vegetative stage. Adjust pH to 5.8–6.2 for coco and hydroponic systems, or 6.0–7.0 for soil-based growing. Pair with Crazy Hills Prosper Bloom 5 Litre when switching to the flowering phase, and complement with the Crazy Hills Kickoff Microbial for a full biological root zone support programme.
