Potassium silicate is a beneficial supplement for your plants; one that will make them bigger, stronger and more resilient to diseases. Calcium magnesium is great because it helps regulate plant growth and productivity and ensures essential chlorophyll levels. These are best used in special circumstances and on an as-needed basis. Our base nutrient formulations are designed to include the required amounts of these elements and compounds when used as a complete system. However, Cal-Mag and Sturdy Stalk are beneficial (or necessary!) if you opt to combine different fertilizer brands or use certain growing media. For example, if you use pure, unbalanced coco coir, a calcium-magnesium supplement such as Cal-Mag is strongly recommended.

Emerald Harvest offers both calcium-magnesium Cal-Mag and potassium silicate Sturdy Stalk supplements.

Hello Irish,

Thank you for your question. It is a very important one at that for our community of growers. To be frank, the shelf life is very strong. However, we do recommend using our products upon purchase as the all natural, plant-based ingredients are most effective when leveraged within a certain time period. With that in mind,

  • Base Nutrients have a shelf life of 3 years or more if kept from getting too cold
  • Organic additives have a shelf life is 2 years or more

Also, please do store them away from direct sunlight and avoid temperatures below 45°F (7.2°C) to avoid crystallization.

Thank you once again and let us know what you think. Does this answer your question? Feel free to comment and let’s discuss.

Hello Rebecca,

Thank you for visiting our website and your question. Absolutely, you can use Emerald Harvest nutrients and supplements in soil. You may need to slightly tweak the measurements on our feed chart according to your pot/container size. And always check your pH before and after feeding. Thanks.

In reply to: Is Coco a good medium

Coco provides excellent insulation. Also, Coco isn’t prone to overheat due to excessive ambient air temperatures like many other mediums (making it ideal for warm geographic zones). This is because water tends to make its way into the lower regions of the coco coir, leaving the top layer relatively drier. Because of this, heat needs to penetrate a drier top layer of coco coir before reaching the watered areas of the media. Since water is a great conductor of energy (in the form of heat) the lower area is comparatively cooler, where the bulk of the root mass is found,. As media temperature and oxygen levels (air porosity) are interrelated (the warmer the media, the less oxygen), this insulation plays an important role in promoting root health and vigor.

In reply to: Why EC is important?

EC is a measure of the concentration of elements present in the nutrient solution. Electrical conductivity is directly proportional to number of dissolved salts contained in the solution. If the EC or ppm is too high than normal, plants will have nutrient burn. Hence, it is important to measure those values and determine the strength of the solution accordingly.

Kerry here are some reasons as to why this is happening.

  1. Overfertilizing – too much food along with moisture stress
  2. High Heat-The plant loses moisture due to high heat, the leaves cup to preserve moisture.
  3. Excess Light-Destroys chlorophyll that leads to U-shaped tips.
  4. Under-watering-Moisture stress and carbohydrate production minimized.
  5. Overwatering: Exchange of gases hindered, an anaerobic condition created which also causes curling.

Take these items into consideration and make the adjustments and you should see very quick changes in your plants.

Hi Gerry,

Thank you for your question about our hydroponic nutrients. The word “synthetic” is a misnomer. Nothing in our nutrients has been artificially synthesized, but some of the ingredients have been mined, which makes these raw materials “mineral” ingredients, not synthetic ones. Because we are firm believers in the benefits and ethics of organic agriculture, our professional base nutrients and supplements contain both mineral and organic raw materials. We use only the finest ingredients in our formulations, and we incorporate naturally derived ingredients whenever we can. We believe we have reached an ideal balance of mineral and organic additives in our formulations. In the near future, we plan to launch a simple, easy-to-use, certified-organic product line, so keep your eyes peeled for that!

Dear Jay,

Thanks for the great question.

Many growers, like yourself, use Emerald Harvest nutrients because it’s so easy to tailor feedings for success in your garden. We recommend that you base your nutrient application on our accurate, easy-to-read feeding charts. Remember that application rates may vary depending on the water condition and what type of growing medium (for example, soil, coco, peat moss, clay pellets, DWC, aeroponics, etc.) you use. In addition, the plant species, size and age should be considered when dialing in the optimal application rates for your crop.

Then you can determine whether or not you need to tweak the application rates on the feeding chart by measuring the ppm of the nutrient solution. Please look at the two tables below. In Figure 1, you can see the recommended safe ppm for all growing mediums except DWC (deep water culture) and aeroponics, while Figure 2 shows the recommended ppm for DWC and aeroponics.

Figure 1—all growing media except DWC/aeroponics:

Week ppm range EC Range Life cycle stage
Week 1 400–600 .8–1.2 Early vegetative
Week 2 600–1000 1.2–2 Late vegetative
Week 3 800–1200 1.6–2.4 Transition
Week 4 800–1200 1.6–2.4 Early flowering
Week 5 800–1200 1.6–2.4 Early flowering
Week 6 1000–1300 2–2.6 Mid flowering
Week 7 1000–1300 2–2.6 Mid flowering
Week 8 1000–1300 2–2.6 Late flowering
Week 9 1000–1300 2–2.6 Late flowering
Week 10 1000–1300 2–2.6 Ripening
  0–400 0–.8 Flush

 

Figure 2—DWC or aeroponics

Week ppm range EC Range Life cycle stage
Week 1 200–400 .4–.8 Early vegetative
Week 2 400–600 .8–1.2 Late vegetative
Week 3 600–800 1.2–1.6 Transition
Week 4 600–800 1.2–1.6 Early flowering
Week 5 600–800 1.2–1.6 Early flowering
Week 6 600–800 1.2–1.6 Mid flowering
Week 7 600–800 1.2–1.6 Mid flowering
Week 8 600–800 1.2–1.6 Late flowering
Week 9 600–800 1.2–1.6 Late flowering
Week 10 600–800 1.2–1.6 Ripening
  0–400 0–.8 Flush

The nutrient charge of the nutrient solution should be measured correctly before applying nutrients to the selected growing medium. A second measurement should be taken from the nutrient run-off after it has been applied to the growing medium in order to assess the correct ppm (or, if you measure electroconductivity, the EC) range.

If you have any other questions, please let us know! We’re here to help.

In reply to: Why run feed in flush?

Dear Jay,

Good question but we got a great answer.

 

 

Flushing the plant with water after charging the growing medium with nutrients is the key to maintaining the correct parts per million (ppm) throughout the crop life cycle. Stair-stepping is a common mistake made by growers by which they add nutrients over and over with little or no water runoff. Below is an illustration showing the effects of incorrect nutrient application:

figure-1-flushing

 

From the graphic above, you can see the ppm rising and falling based on stair-stepping theory with no runoff. Measuring the water runoff correctly is the key to making the correct flushing adjustment. It is a common mistake to add only water to the plants and test the ppm runoff. This gives you a false reading. The correct method is to mix your nutrients first, then test your ppm before and after feeding the plant, helping you decide the correct course of action. Below is an illustration showing the effects of correct nutrient application:

figure-2-flushing

Flushing the plants at the end of the crop life cycle is the key to removing excess nutrients from plant tissues before harvest. Too high a nutrient concentration can make the end product taste bad and even cause a sparkling effect when ignited. On the other hand, too low a nutrient concentration can cause the plant to shut down too soon and prevent proper ripening.

Therefore, having some—but not too much—base nutrient in your growing medium will allow your crop to finish properly. The correct concentration for flushing is 500 ppm or less to achieve optimum flavor in your harvest. Please let us know if you have any other questions and do share with the community. Thnx again.

Best,

Dr. R Sharma

In reply to: What is PPM?

Dennis,

Parts per million (ppm) represents the ratio of a particular mineral in a nutrient solution. A ppm of 1 means that there is 1 millionth of a gram of that mineral for every gram of solution. Parts-per-million levels are used to control the optimal ratios of nutrients in fertilizer and other nutrient supplements. Very good pH tri-meters are available at hydroponic stores that give you a constant pH, ppm and temperature reading of your reservoir. Read more about ppm on Wikipedia.

Checking ppm levels or electrical conductivity (EC) is essential. If these measurements are too low, the plant will starve. If they are too high, the plant is put at risk of “burning” and may die due to oversalination and shock. It is very hard for plants to recover from overfeeding.

Specialty bloom boosters for early, mid and late flowering are unnecessary with Emerald Harvest. Instead, just use King Kola, which can—and should—be applied throughout the flowering phase. This powerful bloom booster contains all the necessary ingredients formulated in the precise ratios to stimulate bud initiation, promote structural floral development, ensure rich ripening and increase yield weights. King Kola will drive your crop to a superlative finish. We guarantee it.

Thank you for your question and for using Emerald Harvest products. Getting the right balance of watering and feeding is important for a healthy, vibrant garden.

A second measurement should be taken from the nutrient run-off after it has been applied to the growing medium in order to assess the correct ppm (or, if you measure electroconductivity, the EC) range.

To figure out what watering/feeding ratio is best for your plants, ppm is a good indicator. The right concentration to maintain in a soilless mix is 500–1000 ppm. So, if your runoff after feeding is 30–50 percent, which pushes through old nutrients rather than letting them accumulate, then you can feed your garden daily. If, however, you have little to no runoff, then you run the risk of overfeeding and “burning” the plants with too high concentrations of nutrients.

We recommend testing the ppm before and after feeding to ensure you stay within the right range. You may find that a cycle of feeding, watering and watering again is more productive, depending on your program.

Feed/Water/ Water is a very common feed regime.

Auto flowing plants can be tricky because they will require an alternate feed schedule. They need a huge amount of Nitrogen for the first two week to promote vigorous growth but then they need to be shifted to a bloom schedule, to start throttling production

Hello Jessica,

Thanks for your message – this a very common question and we are happy to answer it for you. Yes you may use Cali Pro and any other our nutrients and supplements in a nutrient system. Always keep in mind that application rates may vary depending on the water condition and the type of growing medium. In addition, the plant species, size and age should be considered when dialing in the optimal application rates for your crop. So while the feed chart is an accurate assessment for hydroponic feeding, you should in theory tweak the application rates on the feeding chart by measuring the ppm of the nutrient solution. [ Always check your pH before and after feeding and watering ]. Please see the charts —>

Hey Zeke,

Great question and for using Emerald Harvest products. Sorry for the delay – we wanted to get some info from our growers and get you the 100% right answer. Getting the right balance of watering and feeding is important for a healthy, vibrant garden. It’s great that you are using the drain-to-waste (also known as run-to-waste) system because it is easier and less prone to problems in general hydroponics gardening. Emerald Harvest nutrients are made of chelated micronutrients, as well as humic acid, vitamin B1, kelp extract, carbohydrates, silica, hemp seed flour and primarily all natural ingredients.

To figure out what watering/feeding ratio is best for your plants, ppm is a good indicator. The proper ppm ratio to maintain in a soil-less mix medium should be between 500-1000 ppm. So, if your runoff after feeding is 30-50 percent, which pushes through old nutrients rather than letting them accumulate, then you can feed your garden daily. If, however, you have little to no runoff, then you run the risk of overfeeding and “burning” the plants with too high concentrations of nutrients.

We recommend testing ppm before feeding and then again after you feed to ensure that you are staying within the correct range. You may find that a cycle of feed > water > water is more appropriate, depending on your regime.

Feed/Water/ Water is a very common feed regime.
We suggest using Sturdy Stalk right out of the gate to help promote healthy, aggressive growth. But we do recommend  for use on water days only. Our base nutrients are as complete as can be – most pro growers judge brands/nutrient lines solely on the performance of base nutrients. And we only have 4 supplements for a truly complete line. So Cal-Mag, Sturdy Stalk, pH UP and pH Down are additives that can be leveraged based on the growth of your garden and your satisfaction.
