  • Hydrotops Top Heavy Crop

    Hydrotops Top Heavy Crop

    Top Heavy Crop enhances and optimises cellular division and physiological function in your plants. Additionally, the protein mechanisms and carbohydrate metabolism are positively stimulated thus increasing plant growth rate, in addition to the number of branches.and flowering sites produced. Top Heavy Crop will ensure good product density for truly “old school” results. It is usual to see shorter internodal lengths and a more compact branch structure. You may find it necessary to remove some of the larger leaves to allow good light penetration to the emerging branches. Expect to produce a very bushy plant, a shorter vegetative growth period, with an increase in yield and crop quality. Top Heavy Crop increases fruit density and quality to a marked degree, improving flavour, sugar content and aroma as part of the process. The quality of the final product is superb when using Top Heavy Crop…. you won’t be disappointed. Top Heavy Crop may be used in traditional hydroponics, bubbler systems, soil and coco growing and with all commonly used growing substrates.

  • Hydrotops Root Stimulator

    Hydrotops Root Stimulator

    To grow a good shoot, you first need to produce a good root. This is an important maxim in horticulture. To get the best yields from your crop a good healthy root system is essential. Your roots are the foundation of your crop and it makes sense to supply the root system with everything it needs to enable it to deliver a bountiful harvest. bioponic root stimulator is not a nutrient. It can be likened to health insurance for your roots and in turn your entire crop. Available in 1 litre, 5 litre and 25 litres. No plant growth regulators (PGR’S) bioponic root stimulator combines plant-extracted bio-enhancers, vitamins, co-enzymes, silicon, and fractions of fulvic/humic acids blended in an organic complex for easily assimilation and rapid effect. In addition to encouraging a healthy root system, bioponic root stimulator is a strong natural bio-stimulator increasing nutrient assimilation and resistance to stress in your crop

  • Shogun Sumo Active Boost

    Shogun Sumo Active Boost

    SHOGUN Sumo Active Boost is a liquid emulsion concentrate composed of a natural compound called Triacontanol and a plant extract sustainably harvested from the South Atlantic. It has the exact same active ingredients as standard SHOGUN Sumo Boost but has been formulated in such a way that it remains stable in tanks for up to 14 days. As with SHOGUN Sumo Boost, this version stimulates heavyweight nutrient uptake and photosynthesis while increasing the content of sugars, proteins, resins and terpenes.

  • Shogun Start

    Shogun Start

    SHOGUN START is a delicate nutrient formulated to establish early plant and root development. Containing balanced micro and macro nutrients alongside the SmartZen maximiser ingredient. SHOGUN START gives your young plants full strength trace elements whilst still maintaining a low overall strength. Key Features Encourages the movement of auxins from the leaf tip to the rooting point. Accelerates germination. Encourages faster root striking in cuttings. Optimal concentration of micronutrients for healthy development of young plants. This is the same as it would be in a full-strength base nutrient, whilst keeping the NPK low. Usage: Root Feed – Add plain water to your nutrient reservoir or watering can and allow to reach room temperature (If tap water, Ideally over night, to allow some of the chlorine to dissipate, but we know this is not always convenient!). Then add SHOGUN Start at a rate of 4mL/L to your nutrient reservoir or watering can. Before adding the nutrients, reduce the pH to just below 7 and then add your additives and nutrients. Recheck the pH (5.5-6.5) and the EC, making sure that it is no higher than 1.4. Repeat method for tank change/refill. Use for the very early stages of the plants life.
