  • Nutrient Reviews

    Hi all. We've been going through some paperwork and found a whole load of reviews for nutrient companies. I'll post them here in the hope that they will provide a usefull resource for some of you. They are not written as a result of personal experience, rather a brief resume of the information that's out there on the web. I'll post them a few at a time over the next few weeks. If anyone has any personal experience or opinions to add, please feel free to comment.
    So here they are, in alphabetical order. We hope it helps.

    Advanced Nutrients

    Advanced Nutrients began to take shape in 1996 when three men formed Canadian Soilless Ltd., got together with the idea of revolutionizing the hydroponic nutrients industry. Since then they have gone from strength to strength.
    With years of research behind them, Advanced Nutrients now produce one of the largest and most comprehensive ranges of hydroponic nutrients available and supply growers across the globe.
    Advanced Nutrients products contain blends of micro and macro nutrients, hormones, amino acids, vitamins, enzymes, chelates and beneficial bacteria and fungi. Some of the products are almost entirely organic whilst others are synthetic/organic mixes.
    The Advanced Nutrients range includes complete systems that will cater to all the requirements of your plants, saving the grower the trouble of working out concentration levels. They even avoid the need to meter pH.
    Some of Advanced Nutrient’s products, such as the SensiPro Two Plus program, feature formulas that are micro adjusted on a week by week level. This means that the ratio and content of the nutrient changes weekly to suit the exact requirements of your plants as they move through the vegetative stage to flowering and ripening. This is much more exact and effective than just ‘Grow’ and ‘Bloom’.
    Another Advanced Nutrients’ flagship product is Advanced Nutrients Sweet Leaf. This additive, as well as increasing growth, sugars the plant giving the finished crop a sweet aroma and flavor, making for a superior smoking experience.
    With years of experience and thousands of recommendations by growers, Advanced Nutrients is one of the planet’s leading hydroponic and cannabis nutrient suppliers.

      Ancient Organics Nutrients
      Many indoor gardeners like to use natural or organic products so that they have total control over what goes into the plants that they love. For millennia bat guano has been one of nature’s greatest fertilizers and was considered by the ancients as ‘gifts from the Gods’. Even in the modern era the fertilizing properties of bat guano are world renowned and sought after by gardeners everywhere.

      Ancient Organics nutrients are based on the legendary plant boosting qualities of bat guano. Their horticultural products are sourced from ancient fossilized bat guano deposits in uninhabited regions and are available in fine mesh or pellet form.

      There are two principle products in the Ancient Organic nutrients range and both are specialist one part nutrient fertilizers:
      • Bat Guano Grow – A nitrogen rich fertilizer (10-2-1) that supplies enough nitrogen enriched goodness to see your plants rocket through the vegetative stage
      • Primal Harvest – A phosphate guano (0-12-1) that provides bloom dynamics and will ensure that your plants’ needs are met throughout the flowering stage. Primal harvest is naturally formulated with high phosphorous and no nitrogen to channel all of your plants’ energy into creating spectacular blooms.
      Ancient Organic nutrients also offer two, more balanced, products for a greater, all round nutrition:
      • Rainbow Mix Grow – A 5-5-2 fertilizer that comprises bat guano mixed with sea kelp, feather meal, soft rock phosphate, steamed bone meal, sulfate of potash magnesia, cottonseed meal and montmorillonite.
      • Rainbow Mix Bloom – A 1-9-2 fertilizer with the same ingredients as Rainbow Mix Grow, but formulated especially for the flowering stages.
      Ancient Organic nutrients provide solutions for gardeners looking for some of that old school organic goodness.

            Bio-Nova nutrients are available to meet a wide range of plant needs, for both hydroponic systems and soil based systems. They even have a product designed specifically for use in coco substrates.
            For hydro systems Bio-Nova nutrients supply their well known Bio Nova Nutri Nova A&B. This fertilizer is a mineral grow and bloom fertilizer and combined growing and flowering stages means that you only need to purchase one bottle of each, simply mix the correct ration for all needs.

                Bountea Nutrients

                Bountea nutrients come from a family run company with an interesting history. Alaskan John Evans, the inventor of Bountea nutrients, is a grower of giant vegetables who holds 18 Alaskan State records and has 9 entries in the Guinness Book of World Records for his amazing oversized vegetables.

                After many years of growing amazing, super-sized veg, John has decided to share his secret with the world, in the shape of Bountea nutrients

                Bountea nutrients’ range of products is based around their original and flagship product – compost tea. Whereas most compost teas originate from vermi-compost (waste products from wormeries), John believes that the range of micro fauna in vermi-compost is too limited. Bountea nutrients’ compost tea is brewed with sustainably sourced organic Alaskan humisoil and a specially formulated bio-activator that is packed with an extremely effective balance of microbes, fungi and bacteria to provide for the complex and multifaceted needs of your growing plants.

                In addition to this heady microbial brew, the Bountea system includes two more products;
                • Root Web which supports and enhances the mycorrhizal fauna at your plants’ roots, promoting nutrient uptake and strengthening the symbiotic relationship between root systems and the soil
                • Marine Mineral Magic M3, a high quality fish based protein that contains a full spectrum of minerals and trace elements.
                Altogether the Bountea nutrient system delivers a fantastic all round fertilizer that has a proven track record. Unlike the claims of many plant nutrient companies, John’s record breaking exploits with Bountea nutrients are 100% verifiable and the environmentally friendly, family ethos of this company is a huge plus when deciding which plant nutrients are best for your needs.

                  Canna Nutrients

                  Dutch company Canna Nutrients is probably one of the most famous cannabis nutrient companies in the world. Anybody who has spent any time reading and researching marijuana horticulture on the web will have come across the name; and they are famous for a reason. Established in the early 1990s, Canna Nutrients runs the complete manufacture and supply chain themselves; from extensive, scientific research and development of all products, to distribution logistics, advertising and marketing. Canna Nutrients do it all themselves.
                  Canna Nutrients offer the complete range of nutrients to suit all needs. Simplicity is the keyword with Canna Nutrients and they make everything really easy to follow. Even the nutrient ranges are handily named to make it easy to match up the range to your particular set up. So the Canna Terra range is for soil, potting mixes and peat based systems; Canna Aqua is for closed hydro systems (such as NFT, where the run-off is returned to the reservoir); Canna Coco is for use with coco substrates and Canna Hydro is for open hydroponic systems (such as run-to-waste).
                  Canna Nutrients also offer the full spectrum of additives, and again their emphasis on simplicity means that they are separated into two main categories that are visibly distinguishable. Products that assist with plant growth and yield come in the classic Canna Nutrients’ twin bottle, whilst additives that work by improving the nutrient solution itself come in a round white bottle.
                  Maybe the best selling point with Canna Nutrients (and again, it’s all about making it easy) is their impressive, interactive web app ( Simply fill in the details about your set-up in the relevant boxes and the app will do all the calculations for you. Telling you exactly how much of which product to use to obtain the best results.
                  It’s easy to see why Canna Nutrients are industry leaders.

                      Femeg Guanokalong nutrients are that much sought after and, some would say, greatest of all naturally occurring fertilizers, bat guano. Sold worldwide as Guanokalong powdered bat guano by German company Femeg, Femeg guanokalong nutrients are famous across the globe as being the ultimate in bloom nutrients.
                      As well as dramatically increasing the yield and quality of your crop, Femeg guanokalong nutrients is widely purported to improve flavour as well; in the case of home grown marijuana, making for a smoother, sweeter smoke.
                      Although used mostly for flowering, it is not just buds that benefit from Femeg guanokalong nutrients. This nutrient also improves soil structure, stimulates biological activity in the soil and greatly enhances root growth, making for sturdier, more vigorous plants.

                      There are two ways of using Femeg guanokalong nutrients. You can either mix it directly into the soil at a rate of around 1-250. Or you can dissolve it into water to make a concentrated liquid food at a rate of around 1-100. Be aware though that Femeg guanokalong nutrients will only completely dissolve at temperatures of 175 degrees Fahrenheit + (80C) so mix first with around 1 gallon (5 litres) of very hot water.

                          GA Special Spray

                          GA special spray from Dutch cannabis wizards No Mercy is a purpose made finishing spray for use on your marijuana plants during the final stages of growth.

                          GA special spray contains Gibberellic-acid, a naturally occurring chemical acid (not a hormone preparation) which stimulates the production of female hormones within the cannabis plant. Gibberellic-acid is a chemical that is naturally present in all cannabis plants and is the chemical agent widely used in the feminization process employed for creating feminized seeds.

                          The application of Gibberellic-acid with the GA special spray, and the stimulation of female plant hormones, serves to increase flowering, making for more abundant blooms and heavier resin production.

                          GA special spray should only be applied to healthy, vigorous plants, and only during the correct period of flowering (see instructions for more detail). It is possible to add GA special spray into the nutrition and this will enable you to treat twice as many plants with the same amount of spray. Apparently results can be quite dramatic under these circumstances, but you should contact No Mercy for more information regarding your particular strains and set-up.
                          Applications of GA special spray will require your plants to wait an extra week before harvesting, it takes an extra week for them to gain the extra weight, so plan accordingly.
                          A final word of warning; with some Sativas the use of GA special spray can promote hermaphroditism, so once again, follow the instructions very carefully and contact No Mercy with any questions or for more information.

                              Green Sensation Nutrients

                              Green Sensation nutrients is a bloom stimulant and booster from Plagron nutrients. Especially designed for the final four weeks of flowering, Green Sensation nutrient works by directly supporting, and enhancing, sugar production within the plant. This, in turn, leads to a more rigid cell structure, strengthening the plant and increasing yield.

                              Results from using Green Sensation nutrients can be dramatic and are easy to achieve, even for the novice gardener. Because Green Sensation nutrients have been designed for the final stage of flowering, you need to have an idea of how long your chosen cannabis strain’s flowering period lasts. Then, just start adding Green Sensation to your weekly feed four weeks before it’s time to harvest.

                              So for example, with a short flowering strain like Early Misty, start treatment with Green Sensation after four weeks of flowering; with a medium flowering strain such as Sour Diesel start adding Green Sensation nutrients after six weeks; and for long flowering strains, such as most of the Hazes, start treatment after eight weeks of flowering.

                              To use Green Sensation nutrients, just mix the recommended dosage with lukewarm water and add to the nutrient reservoir. Then stand back and watch your babies bloom.
