Our products are lower on the pH scale than many salt-based formulas due to some organic inputs. These inputs allow the plants to naturally buffer the rhizosphere without negatively impacting nutrient uptake. Therefore, we don’t recommend adjusting the pH as long as the solution falls between 3.0-6.0. If the pH falls below 3.0, adjust pH levels using potassium hydroxide; do not use potassium carbonate or potassium silicate. If the pH rises above 6.0, adjust with phosphoric, nitric or sulfuric acid.
Rx Green Technologies’ nutrients are formulated to run in many different systems, including drain-to-waste system, recirculating systems, and drip irrigation systems in soil and soilless media. For best results with recirculating systems, change and clean the nutrient reservoir every 7 days.
Add one part to water, mix thoroughly, then add next part to water. Do not mix two concentrates together before adding to water. This can lead to chemical burns and/or chemical reactions that will change the nutrient profile.
Due to the organic components in products, especially E-PLUS, a biofilm may form in solution if left standing for more than 3 days. This can lead to an unusual smell, clogged drip lines or altered nutrient availability.
The organic components may cause the color to vary over time. This does not affect the products.
Unopened products are stable for a minimum of two years. Once opened, they will remain stable as long as there is no external contamination. If products freeze, they can be thawed and used according to instructions after thorough agitation. Products can sustain temperatures up to 120 degrees without adverse effects.
All raw materials are pharmaceutical-grade, sourced from suppliers in North America.
Our products have a low pH, and are most effective when the pH is unadjusted. The organic acids in our products will cause some upward pH fluctuations as the plant is feeding. This is normal, but expect to see more rapid changes in recirculating and aerated systems. When mixing your solution make sure it is in the ideal range initially, and if it rises above 6.0 in the following days adjust back to the ideal range of 3.0-6.0.
Our nutrients do not hold an Organic Materials Review Institute (OMRI) certification at this time. We believe that a blend of elemental minerals and natural additives provide the best possible nutrition for plants grown in a variety of systems. Organic fertilizers require organisms to break down nutrients into a form that plants can absorb. This can be difficult to stabilize and may produce inconsistent results in a hydroponic growing environment.
Rx Green Technologies’ products do not contain any synthetic growth hormones or regulators, but do contain naturally occurring hormones from plant-derived materials.
We do not recommend leaving nutrients in your reservoir for more than 4 - 7 days in a recirculating system. If you are having problems with your reservoir developing a biofilm or getting murky, you may need to change the solution more often. We recommend adding hydrogen peroxide, hypochlorous acid or quaternary ammonium salts to help stabilize pH and combat pathogens in the nutrient solution.
Because we designed our nutrients for use on cannabis, and we understand cannabis is often smoked, we committed to create products with low levels of heavy metals for cultivating plants that will be safe for human consumption. We did so in two ways: use of pharmaceutical grade minerals and excluding animal-based ingredients. The levels of heavy metals in cannabis grown with our nutrients are essentially non-existent.

We do not recommend leaving E-PLUS in your standing reservoir for more than 24 hours. The product performs best when mixed and then used immediately.
Due to the organic components in E-PLUS, biofilm may form in recirculating and drip emitter systems if not properly sanitized or pressurized. See our website for more information on best management practices with irrigation systems.
BULK is a PK booster specially formulated for cannabis to improve plant performance, yield and quality. Our exclusive technology allows for calcium and phosphorus to be combined together in one product, reducing the need for additional supplements.
While trichome and oil production are largely dependent on environmental conditions and plant genetics, the nutrients in BULK are essential for the increased metabolism during the reproductive phase. Calcium, potassium and phosphorus are all required in larger amounts during this stage for the biochemical pathways and enzymes used by the plant to produce oils and trichomes.
The inclusion of extra calcium in BULK contributes to density, or “hardness,” by increasing the dry matter content of the finished flowers. Potassium also helps to increase weight and density.
BULK was formulated to give the plant exactly what it needs during flower stage to increase bud density and dry bud weight most effectively. This formula was tested against many other solutions with varying amounts of potassium, and our current formula provided the top results.
LIFE Cloning Solution contains no synthetic growth hormones. LIFE does contain a low-salt, safe, and effective formula that will aid in root development up to 20% faster than leading brands.
Add GROW A or increase LIFE Cloning Solution. LIFE Cloning Solution is a unique formula; it not only triggers root development in cuttings, but it also facilitates top growth. As a result, your plants may need additional nitrogen to fuel this growth.
It is protected from degradation by thyme oil, which is a naturally occurring biocide. Typical rooting hormones in the market use a chemical biocide such as 1,2-benzisothiazol-3(2H)- one, which has known health and environmental concerns.
Seal and keep in a cool dark place. The shelf life of LIFE Cloning Gel is two years; extreme hot or cold conditions can reduce the shelf life once opened or exposed to the air.
Do not dip cuttings directly into gel containers. Pour off the desired amount into a small, washable or disposable container before dipping cuttings.
Yes. Rx Green Technologies’ formula includes inert buffers that allow for easy application and mixing with water.
AXIOM contains 1% Harpinαβ protein and 99% other ingredients. Harpin proteins are very powerful; only a small amount generates strong plant health and growth. The other ingredients are inert food-grade non-toxic substances.
Reseal using a paperclip or other device and store in a cool dark place. You should use AXIOM within three weeks of opening. Refrigeration can help preserve it for longer.
First, AXIOM should be applied to the plant canopy as a light mist therefore no burning should occur (2 g mixes with 1gallon and covers 1,000 square feet). Total coverage of the plant is not required. We recommend using AXIOM right before or as the lights come on, since the product triggers a photosynthesis response in the plant. This response is much more effective while the plant is actively photosynthesizing.
We recommend applying up to two weeks before harvest. AXIOM is a protein and is absorbed by the plant. It is allnatural and non-toxic, but if you are nervous about using a foliar application in the late flowering stage, you can apply it only to the lower fan leaves. Because AXIOM works systemically, once the plant detects the harpin proteins, it will generate a plant-wide response.
The bacteria in ROOT are plant-specific and are not harmful to humans.
It is best to apply ROOT according to the label rates however, even significantly over-applying ROOT will not cause damage to your plants. It is microorganism-based, so only those organisms that receive enough food will survive, and the rest will simply die off.
The bacteria activate and multiply when mixed in water, resulting in foam.
It is not recommended to add pH adjusters to water when mixing with ROOT, as this can damage the microbes.
No. The beneficial microbes are effective at the root zone, breaking down nutrients into more available forms.
Formononetin is a naturally occurring compound, originally discovered in plant roots with drought stress. It is proven to stimulate mycorrhizal activity and improve nutrient solubilization and availability.
We do not recommend ROOT for use in a recirculating system. It can cause foaming and bacteria build up that is difficult to clean.
This product is safe to apply until harvest, but use caution in late flower to avoid damaging pistils.
Yes, FORTIFY FUNGICIDE can be tank mixed. We suggest a jar test before mixing an application batch. To tank mix, add 50% of the water volume followed by FORTIFY FUNGICIDE and mix thoroughly. Then add the second product and mix thoroughly. Lastly, add the final 50% of water. Since this an oil based product, components can separate if left in water over time.
The active ingredients have been shown to be effective against many fungal diseases but this product was only tested on powdery mildew
No, this product is for foliar application.
A variety of different sprayer types can be used to apply FORTIFY FUNGICIDE. Ensure that sprayers used can be properly calibrated to give accurate doses of pesticide per coverage area. Inaccurate sprayer calibration can result in poorly applied pesticides that do not control pests.
Yes. High volume hydraulic type sprayers usually cover 200-400 sq. ft per gallon. Low-volume sprayers such as foggers usually cover 5000-10000 sq. ft per gallon. Backpack sprayers with a boom and flat fan nozzles attached can be calibrated appropriately for this use. Higher volume applications can ensure better coverage of leaf surfaces. Consult your sprayer manual to determine appropriate carrier volume and product rates for your sprayer type.
Spray with lights off for best results. Allow plants to dry before turning lights on. This product can be applied under direct light with minimal phytotoxicity, if applied within recommended rates.
Spray in early morning or late evening for best results. This product can be applied under direct light with minimal phytotoxicity, if applied within recommended rates
CLEAN COCO is made of coco coir. Coco coir primarily consists of the coir fiber pith or coir dust obtained by processing coconut husk and removing long fibers. The chemical constituents of coco coir include cellulose, lignin, potassium, phosphorus, chloride and sodium. There are also trace amounts of nitrogen,
Coco coir fibers are the result of harvesting coconut fruit from the outer shell. The fibers are then gathered into large piles to be rinsed. Because coconuts grow in a tropical climate, rains during monsoon season thoroughly rinse the coco coir fibers. The coco is then dried and shipped to our US manufacturing facility. We rehydrate the coco, add perlite, and send it out to you.
CLEAN COCO should be flushed with plain water at regular intervals. This will prevent salt buildup and nutrient lockout. Plants potted in a coco substrate that are fed a high EC nutrient solution may experience salt stress if the medium is not rinsed throughout the growing cycle or allowed to drain more freely. If one or more daily feedings are provided, the EC should be lowered accordingly and weekly plain water feeds should be applied as necessary.
