With over five years of research and development, Hydrotops Top Heavy Crop is a tried and trusted, 100% organic stimulant, for use not only in the flowering cycle but the vegetative cycle as well. When used in veg, Hydrotops Top Heavy Crop promotes shorter, bushier growth in plants and an increase in lateral flowering sites. Thanks to this increased growth rate, you’ll decrease veg times across the board, allowing you to cultivate more crops per year than before with no decrease in yield; in fact, quite the opposite! The result of this shortening of veg time and node length is denser and more abundant flowers at harvest and, as with all Hydrotops products, there are no plant growth regulators or PGR’s involved, only pure organics from start to finish.
Add to the nutrient solution 7 to 10 days prior to flowering/fruiting and continue adding on a weekly basis and with every tank change until you begin to use Triple F.
Between days 10 to 20 of the flowering/fruiting period spray the plants well until the point of runoff every three days with a full-strength Top Heavy Crop solution made up as discussed in the directions for mixing. Add to the nutrient solution or add to your growing medium every week once you have discontinued using Triple F until harvest, including the flushing period.
Store in a dark place and protected from frost. if the product comes into contact with the eyes, rinse with water. Keep out of reach of children.

Using nutrients for hydroponics
Nutrients are the basis of any hydroponic system and since we need to meet all of the plants’ nutritional requirements, it’s important to know what you are supplying and what can go wrong. With any nutrient solution the two factors to keep in mind are firstly the composition of your nutrient – does it contain all of the elements required for plant growth in the correct ratios. And secondly, with your balanced and complete nutrient solution, what strength or ‘EC’ should it be running at for your particular crop, stage of growth and type of hydroponic system, and how do we measure this.
The nutrient solution – composition
Many growers prefer to buy a ‘pre-mixed’ nutrient solution which simply needs to be diluted (for liquid concentrates) or dissolved in water before use. Often these ‘pre-made’ nutrients come in 2, 3, 4 or even more ‘parts’ so a grower can change the ratio of the mineral elements to allow for either vegetative or fruiting growth or for different crops. There are many excellent brands of these pre-mixed nutrients on the market, however, many growers have come across major problems when they try to use some of the ‘indoor plant food’ or other nutrients which have been designed for plants growing in soil or a pre-fertilized potting mix. Often these types of products are not suitable for hydroponics because they are not designed to be a ‘complete plant food’. It is always preferable to buy a nutrient mix that is sold especially for ‘hydroponic’ use and is ‘complete’ plant food. To be ‘complete’ a hydroponic nutrient needs to have the essential elements for plant growth these are:
- Nitrogen (N)
- Potassium (K)
- Phosphorus (P)
- Calcium (Ca)
- Magnesium (Mg)
- Sulphur (S)
- Iron (Fe)
- Manganese (Mn)
- Copper (Cu)
- Zinc (Zn)
- Molybdate (Mo)
- Boron (B)
- Chlorine (Cl)
The levels that these elements are present in your hydroponic nutrient tend to vary between brands since there is no one single recommendation for concentrations. Many nutrients may also contain some of the ‘beneficial elements’ such as Nickel (Ni), Cobalt (Co), Silica (Si) or Selenium (Se). While these are not ‘essential’ (plants will still grow without them), they can be beneficial to many crops.
Whether you make your own nutrient solution from the different fertilizer salts or buy a pre-made brand, problems can, an often do, arise with deficiencies of one or more of the nutrient elements. Common reasons for this are that (1) the nutrient strength may be too low, resulting in insufficient nutrients for the plants in general. (2) The nutrient formula you are using may not be completely balanced, and one (or more of the elements) may be deficient. (3) Occasionally, growers may unintentionally leave out one of the fertilizer salts or the wrong fertilizer was used when the nutrient formula was weighted out. And just to complicate matters further, even if your solution is well balanced, sometimes environmental and internal plant conditions prevent the uptake of certain nutrients and deficiency symptoms then result.
Signs of Deficiency
Each of the mineral elements required by the plant has its own set of ‘deficiency signs and symptoms’ and growers can learn to identify many of these. Many of the signs are similar in appearance, but others are very distinct and most good gardening and hydroponic books will detail what these signs are. Briefly, the deficient symptoms for each of the elements are listed below (these may vary slightly between different plant species and depending on how severe the deficiency is):
Nitrogen (N): Plants are short, leaves tend to be pale green-yellow in colour, especially on the older foliage. On tomato plants, the undersides of the leaf and stems can develop a purple colouration.
Phosphorus (P): Plants are usually stunted, and a dark green colour. Symptoms occur on the older leaves first and plant maturity is often delayed. Phosphorus deficiency in some plant species can be due to conditions being too cold for the uptake of this element, rather than a lack of phosphorus in the nutrient solution.
Potassium (K): The older leaves become yellowed with scattered dark (brown or black) spots, followed by tissue death. A severe deficiency will stunt the plant and all foliage will become yellowed and curled. On lettuce, the leaves may take on a yellowed, bronzed appearance starting on the older foliage.
Sulfur: Deficiency of sulfur is not common – there may be a yellowing of the leaves, first seen on the new growth.
Magnesium: Deficiency is common on tomato crops with the older leaves developing yellowed areas between the veins which stay green.
Calcium: Young leaves are affected before older leaves and become distorted, small in size with spotted or necrotic (dead) areas. Bud development is inhibited and root tips may die back. Tip burn on lettuce is a symptom of calcium deficiency but is also caused by other factors not associated with a solution deficiency. Blossom end rot of tomatoes is also caused by a deficiency of calcium within the fruit tissue (not necessary in the nutrient solution) and is more of a ‘calcium transport’ problem within the plant under certain environmental conditions.
Iron: Deficiency shows as a distinct yellowing between the leaf veins which stay green, on the new growth and younger leaves (this distinguishes it from magnesium deficiency which shows first on the older leaves). On crops such as tomatoes, iron deficiency may show when conditions are too cold for uptake, rather than be caused by an actual deficiency in solution.
Chlorine: deficiency shows as wilted leaves which then become yellowed and necrotic, eventually turning a bronze colour.
Manganese: Initially, an interveinal yellowing on the younger or older leaves, depending on the plant types. Brown, dry areas may develop and leaves may drop.
Boron: Plant size is usually reduced, the growing point may die back. Root tips often become swollen and discolored. Leaves eventually become thickened, brittle, and maybe curled with yellow spotting.
Zinc: Short plants with a reduction in internode length and leaf size. Leaf edges may be distorted or puckered, Yellowing between the leaf veins may also develop.
Copper: Deficiency is rare, but young leaves may become dark green and twisted or misshapen, often with brown, dry spots.
Molybdenum: Older leaves develop interveinal yellowing, progressing to the younger leaves. Leaf edges may develop scorching or cupping of the leaves.
Solution strength – under and overuse, measurement
Provided the nutrient you are using is complete and balanced, the concentration or strength of the solution has major effects on plant growth and development. This is why it is essential to be able to measure solution concentration, using a meaningful unit of measure. Many growers will still be working in ppm, using TDS meters, however, there is now an industry move to standardize the unit of solution measurement to EC (electrical conductivity) which is a more accurate and meaningful way to monitor your nutrient. All a TDS or ppm meter actually does is to measure the EC of the solution, then use an approximate conversion figure to convert this to PPM. The problem arises is that this conversion figure is never very accurate, as different nutrient solutions with different compositions of nutrient elements will have different PPM values so using one conversion figure can be extremely inaccurate. What the plants’ root system is actually responding to is the EC (or osmotic concentration) of the nutrient so this is what we should measure. There are a number of different EC (sometimes called CF) meters, and the ‘water-resistant’ pen-type meters are commonly used by growers. Depending on where in the world you are, the units expressed on your meter may be different, however, it is easy to convert between the different units of EC.
“There is no particular smell to this product and if there is its not nasty, my husband swears by this liquid for feeding all his plants,
He uses this all the time and it does help the plants, he’s a keen gardener so we gave lots of plants we do recommend bit.”
“This stuff is absolutely brilliant. My friend told me about it years ago and I apply it to everything in the garden except the weeds of course, hahaha!”
“This product does what it says of the container very good quality for all your gardening needs“
When designing our biOpOnic nutrient range back in 1998 the principal aim was to combine organic horticultural chemistry with the spirit and ethos of the organic grower, drawing upon in-depth knowledge of hydroponic growing and nutrients. HYDRoToPs were the first UK based nutrient manufacturer, and whilst our products have evolved over the last 16 years our aims have remained the same; to produce high-performance bio-organic nutrients that deliver consistently outstanding results for both hydroponics, coco and soil growers.
HYDRoToPs is proud to have introduced many groundbreaking ideas and concepts to the hydroponic world. One such example is our legendary Triple F (Fully Formed Flowers). Introduced to the world in 2002 it was the first fruit and flower enhancer to increase yields by up to 40% whilst remaining 100% organic. Triple F continues to prove itself time after time as the finest natural flowering enhancer available to date. Its introduction to the market over 10 years ago prompted a number of flower boosting products to emerge from other manufacturers. Sadly many of these products have evolved from using plant growth regulator (PGR) chemicals to achieve their results. Whilst many of these products are successful at producing additional flowers and increasing yields, we believe nature offers the best solution every time.
Many of the PGRs used in boosters today MUST be licensed and are for use on non-food crops ONLY. There is a reason for these regulations to be in place since many of these chemicals are known to have carcinogenic effects and may be linked to the development of serious medical conditions. HYDRoToPS never has and never will use PGRs or other dubious chemical additives which may cause harm. Alarmingly enough some PGRs are yet to be classified or approved and little or no research has been done on the potential risks to health or the environment. PGRs have found their way into several manufacturers’ “boost” products hailed as a breakthrough in growing technology. Most have been banned in the USA owing to their associated health risks. Whilst some growers may not be driven by conscious choice in terms of which products they use, many are consciously opposed to using products that may cause harm to the individual or environment. HYDRoToPS gives you a better result naturally without recourse to potentially dangerous compounds and chemicals.
We are always actively researching and developing our products and we are excited to announce some new additions to our range, which will be released in the coming months. For example our Next Generation range of nutrients, plus Top Heavy Crop (THC) – a formidable new growth and flowering enhancer. Along with Top Heavy Crop, we are also proud to be releasing HYDRoToPS Solo nutrients in January 2013, a simple single part nutrient for hydroponic and soil growing. Easy to use with truly professional results in a single bottle, again another first for HYDRoToPS.
The word hydroponics derives from the Greek to mean “water working”. HYDRoToPS was the first company in the world to introduce the concept of nutrients tailored directly to your regional or personal water supply. In order for your water to work for you, the nutrients you use need to be chosen carefully and balanced to your water supply. Within this web site, you will find an in-depth explanation of water quality and plant nutrients, allowing you to make the best decision when choosing your own nutrient requirements thus allowing you to achieve maximum results from your efforts.
HYDRoToPS have been producing custom nutrient formulations for UK growers since 1996 and continues to do so to this day. We also were the first to manufacture area-specific nutrients covering all of the UK by 2005. Over the last 13 years, we have analyzed thousands of water samples from all areas of the UK and our database of water quality second to none. We are very proactive in the maintenance and expansion of our water quality database, constantly re-analyzing water samples from growers and HYDRoToPS distributors, free of charge. This helps us to maintain the excellent quality of service growers throughout the country have come to expect. This ensures our products are the most effective and productive nutrients available in the UK today.
