It is best to use a pressure sprayer to apply the foliar as this will deliver a fine mist, however, you could use any spray bottle. If managed well, seedlings develop into strong young plants that go on to be solid producers. Thanks again!!! I confirm that the pH is 6.2-6.4 before applying the solution to the coco. Start with daily watering, however by the third or fourth day of fertigation, you can increase frequency to twice daily. Because pH imbalance makes it difficult for the plant to absorb nutrients with its roots. Plant has three nodes. Ph is also coming out around 6.9-7.0. Once the coco is drying out more quickly, you can up the amount of water you’re giving until you’re getting 10-20% runoff each time. I grow in coco so I can see how they react within a day or 2 normally. For complete instructions and photos of the process be sure to see "Transplanting Cannabis Plants: Why, When & How”. However, during the grow, more cation exchange sites are continuously exposed, which require additional CalMag. As soon as you see the first indications of seedling calcium deficiency begin treating them twice daily with a CalMag foliar spray. Without the right climate characteristics, the young plants will not live up to their full potential. However, once the cotyledons open the plant will begin to fire up its ability to photosynthesize light energy. We advise strongly against placing small plants into large final containers. This should not be a problem early on. This flush is important because otherwise the residual high EC from the buffering process could burn your sensitive seedlings. You will eventually get to final containers, so be sure to read our recommendations in “Pot Size and Type: The Best Containers for Cannabis in Coco” (Coming Soon). Buffering your coco is critical to help ensure a smooth seedling stage. This means that a 15-25 watt fluorescent or LED propagation light is perfect for seedlings. Plants can absorb calcium through their leaves and in this way the plant can get it without having to compete with the coco for it. Be sure to see our article, “Why and How to Use CalMag in Coco”. If symptoms deteriorate despite the foliar treatment, then you should substitute CalMag water in place of the regularly scheduled nutrient solution. These peat-based media provide a more stable buffer for germinating seeds and sprouts. Sometimes the edges of the leaves look wavy as a result. Keeping higher relative humidity reduces the stress on seedlings. my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength. You can often observe this on the leaves of seedlings on the first two nodes. Therefore, it is best to avoid any fertilizers and keep germinating seeds and sprouts in low EC water. If you rinse your coco coir more than three times and it’s still showing 450 or more ppm, and/or the pH is out of range, do not use that coco coir. Check out our Product and Equipment Guide for our Recommended Grow Lights, Grow Set-up Equipment, DIY Projects, Germination Supplies, Plant Training Supplies and everything else you will need during the grow! We may receive a referral when you purchase products through our links. When it comes time to place seedlings into coco, I fill the seedling container with coco/perlite and then flush it by pouring pure water with a pH of 6.5 though the container until the run-off is less than EC 100 (0.1). When I begin a grow, I prepare and buffer enough coco for the final containers. Vegged between 4-500, nothing burnt maybe a lil light! It took her a total of 14 days from seed to graduate the seedling stage. However, you can mix a smaller batch, just add enough CalMag so that the EC is 800. pH should be above 6.2. The Coco for Cannabis Seedling Blend Recipe will produce a nutrient solution with an EC of about 1000. During the seedling stage it is particularly important to provide nutrient solution that is the correct strength as measured by Electrical Conductivity (EC). The distance between your lights and seedlings will depend on the intensity of your lights and some experimentation will be needed to find the right height. The Science and Practice of Growing Cannabis. How to Prepare Coco for Seedlings. Therefore, it is important to reduce the residual EC in the coco before transplanting the seedlings. Whether a cannabis plant is planted in soil, coco, or hydro, pH levels need to be maintained to optimal levels. Using the watering syringe allows you to carefully water around the pellet or rooter and saturate the coco. Seedlings in coco coir grow far faster if you start them off with seedling-strength nutrients from the beginning! The humidity and temperature are very important during the early stages of growth with seedlings. then slowly taper off. I have just purchased a PPM meter and wanted to know what PPM I should be using? Around 400. Once the cultivator reduces the photoperiod to induce flowering, the plants will do their best at 1000-1100 PPM. I keep the bulk of the coco/perlite moist with CalMag Water in fabric pots until I need it. I use a giant 60ml oral syringe to fertigate my little seedlings. Very young seedlings or clones will appreciate receiving water with a PPM reading of 500-600 PPM. I had a buddy that went off to grow for some guys in Oregon that said they swore by dina gro foliage pro/mag pro/protekt at 350 ppm all the way through in promix. For more on light cycles and why we recommend 18/6 lighting for seedlings and vegetation, be sure to read our article, “Cannabis Light Cycle Fundamentals”. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . The seedling bags create an ideal environment for young roots, however the solo cups are somewhat easier to transplant out of at the end of the seedling stage. If you still have a dome or cup over your plants, they should be removed now, and a light breeze applied to the plants. As an Amazon Associate, we earn from qualifying purchases. You may need to either heat or cool your seedlings in order to achieve the correct temperature. When your little plants grow to three nodes they have graduated from seedling status and can be considered little plants. At Coco for Cannabis, our mission is to help growers maximize the success of their cannabis crops by providing scientifically accurate information and sharing proven growing practices. Stretch was over early this week & went up to 700 ppm this nute batch. PPM Levels I recommend beginning to fertigate (add fertilizer to the irrigation water) when two conditions are met: If the cotyledons are already open prior to transplanting into coco, then it is a good practice to presoak the coco in the seedling pot with nutrient solution at the appropriate pH and EC prior to adding the seedlings. Plants at different stages of growth will need different levels of EC. This is because the coco is taking the Ca and Mg from the nutrient solution. As I explain in the article, “Why You Need Cal/Mag in Coco”, the coco itself has cation exchange sites that need to be filled with calcium or magnesium. We recommend growing sprouts first in a Rapid Rooter or Jiffy Pellet before transferring to coco. I keep a thermometer/hygrometer probe right next to the seedling to ensure that the temperature does not get too high and that the humidity does not get too low. The coco will take its share of the calcium and magnesium before the plant has a chance, so if you do not provide enough, the plant will suffer. Fertigate twice: #1 EC 976, pH 6.0; #2 EC 1012 (Full strength), pH 6.2. The first sign of calcium deficiency is a slight twisting of the leaves. If it's going up your starting water quality is too high in dissolved minerals. Howdy, So I brewed another batch of compost tea to feed my new project: 3 pots of coco/perlite 50/50 feeding nothin but compost tea. The end of the seedling stage is also when you should think about training your plants, so be sure to read our article, “Why You Should Train Cannabis Plants” and see our training tutorials. So there you have it. Before proceeding here, be sure to see my video and read our tutorial, “How to Mix Nutrient Solutions for Cannabis”. As the plant continues to grow during the vegetative phase of its life, it will benefit from water with a higher PPM reading of 800-900. As you will see below, each grow and each plant are a little different. This practice helps to satisfy the coco’s craving for calcium, but it cheats the plant out of some other nutrients. Calcium and magnesium deficiencies are common problems with plants grown in coco. I need to understand how this PPM thing works. The optimal pH and EC values for cannabis cultivation are contingent upon three factors, the growing substrate, nutrients and water. If symptoms progress, you will notice brown spots form on the leaves. Roots Out from the bottom of seedling Bag! So from now on I feed my base nutrients at full strength (4mL per liter) and use my other nutes at 1/4 to 1/2 depending on how they look. This may cause some plants to blow over if the stem is too weak. The information on cocoforcannabis.com should not be considered as financial, legal, or medical advice. Im using coco mixed with perlite for my grow atm, they are in week 3 of flower, however i noticed that my runoff ppm is way lower than it should be. As the plants start maturing during the seedling stage, it is time to work your way through a transplant strategy. When you suffer calcium deficiencies in the seedling stage you need to carefully consider the coco you are using and your buffer before transplanting up. So i finally got a PPM/EC Meter. I have some plants in coco coir and first they looked damn good in the seedlings/earlyveg/veg stage. Continue the foliar treatment until the seedlings are on the full-strength seedling blend. PPM Levels for Cannabis Plants. The seedling stage starts when the cotyledons (first round leaves) open, usually around 3-4 days after the seed gets wet. When you do this, you need to be sure that the CalMag water has the same EC that the water it is replacing would have had. I'm using a&b with cal-mag, plan on topping out at around 900 ppm mid-flower. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum. If you use solo cups, be sure to cut numerous holes in the bottom of the cup to allow drainage. However, once the root is in media and the head emerges from the Rapid Rooter or Jiffy Pellet, the lights should come on. The Science and Practice of Growing Cannabis. In most cases, they will be ready to be transplanted out of their seedling pots and into the next home. Easy to follow instructions to produce great weed plants for novice growers and experts alike. Watering and feeding cannabis plants cultivated in coco coir is a relatively simple transition for hydroponics growers and organic growers. However, buffering solutions themselves have a high EC, and seedlings could be burned if they are placed in coco fresh from the buffering process. If you are using a different line, be sure to follow the ratios provided by the supplier for the base nutrients. Especially with RO since coco is inert. I haven't been having good luck with feedling at the ml/L in peat, lots of nute burn issues, PH issues etc. However, it is best to avoid the problems in the first place by properly preparing your coco. However, during the seedling stage it is helpful to keep a somewhat higher RH. Be sure to see our tutorial, “How to Prepare and Buffer Coco Coir”. Note: Soil-grown plants tend to need a little bit higher of a pH than hydroponics because soil retains and releases certain elements to your plants at different times. Fertigate twice: #1 EC 851, pH 6.1; #2 EC 902, pH 6.1, Roots out from the bottom of seedling bag! Seedlings must be started with a nutrient solution that is very low strength as measured by Electrical Conductivity (EC). Adding a wetting agent to the foliar solution is optional. Coco should never be allowed to get very dry. During the seedling stage the relative humidity should remain high, 65 – 80% and the temperature should be moderate, 72-79f (22-26c). Hence, this tutorial covers roughly days 3-15 from seed. On the one hand, adding nutrients to the water helps the plant grow. When the root emerges, we recommend placing the plants into either fabric seedling bags or solo cups with prepared coco. I mix one gallon of full strength seedling blend solution prior to the first fertigation. Therefore, during the seedling stage, it is best to keep the intensity of light low. However, both hydroponic and soil pH levels should stay within the same optimal range of 5.5-6.0 pH. CalMag has a strong impact on EC so when seedlings do suffer Ca or Mg deficiencies, they can be tough to correct. Transplant to second container: End seedling stage. Go back and adjust the pH of the of the gallon, keeping in mind how the sample was affected by dilution during the first attempt. As I explain in the articles “Growing Cannabis in Coco Coir with High Frequency Fertigation” and “Understanding EC, PPM & TDS for Growing Cannabis”, fertigation always requires a balance. Thanks for the good informations. Slowly raise EC from 400 to 1000, Learn how to treat calcium and magnesium deficiencies in seedlings in coco, See example photo timelines of germination and seedling stages, Transplanting Cannabis Plants: Why, When & How, The Best Environment for Growing Cannabis, Growing Cannabis in Coco Coir with High Frequency Fertigation, Understanding EC, PPM & TDS for Growing Cannabis, How to Mix Nutrient Solutions for Cannabis, Germinating Cannabis Seeds – A Step by Step Guide. I've been feeding them PH 5.8 tap water with weak nutes, rhizotonic and every 3rd feed 1ml of calmag. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. The other 999 ml is water. The amount of water needed for each event is very small because the seedling pots are small, and you never allow them to get very dry. We recommend that you always use a transplant regime and never start seedlings in final containers. You can use various strategies to achieve the correct RH. It is very difficult to accurately adjust the pH of a small sample of solution. Everything you read from people says to gradually increase every week until you're close to or over 1000ppm. Before you use coco, it should be properly rinsed, buffered and mixed with perlite. To help with drainage and to encourage root growth it is best to avoid watering the top of the Rapid Rooter or Jiffy Pellet. Today, coco coir is the favourite substrate of many growers for growing cannabis, either indoors or outdoors.Although it is mainly used by experienced farmers, growing with coco coir is easy if you follow a few basic steps. Substitute CalMag Water for first fertigation EC 794. PPM in 10 Seconds PPM is a measurement of nutrients in the soil or growing medium. Try using a lower ppm water to start off when making your nutrient solution. Please see our Product and Equipment Guide. For those crucial first 3 days, be sure to see our tutorial "Germinating Cannabis Seeds - a Step-by-Step Guide". Plant has three nodes. During the flower stage, optimum parts per million rises to 1000-1100. There is also TDS, and PPM, which can be used to measure the salt content of a solution. Once I have the gallon mixed, I pour a small amount into a separate container and then dilute that with filtered or bottled water until I reach my target EC for that fertigation. This is because young seedlings have underdeveloped roots and it can be difficult for them to pull adequate moisture from the soil. Fertigate twice: #1 EC 608, pH 6.2; #2 EC 659, pH 6.2, Fertigate twice: #1 EC 750, pH 6.2; #2 EC 815, pH 6.2, Signs of calcium deficiency, begin CalMag Foliar applications twice daily. If the coco is properly buffered these problems can be managed and will subside as soon as you are able to fertigate with full strength solution. This allows you complete control of their RH as long as they fit in the dome and you use a hygrometer. Organic soils are too comple—x to be analyzed with ordinary PPM readers. If plants are too cold or too hot, growth will be reduced as biological processes, especially photosynthesis, are directly influenced by temperature. The buffering process is crucial to prepare the coco for plants, and especially seedlings. That energy is quickly depleted, so plants are in a race to grow their leaves to be able to capture their own energy through photosynthesis. A CA boast may be necessary, coco is notorious for being able to store (and not make available) large amounts of Calcium. “Blueberry” from Seedsman was a fast-growing seedling. We have a wonderful community of growers and you are welcome to join! Conversely, if the seedling gets too much light it can damage photosynthetic systems and other cellular components. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. When plants are still seedlings, the amounts needed for each fertigation event are very small. Most seeds will not quite keep up with the pace that she set. At mid flowering about 1 ml of a 1 liter watering can of water is nutrients. You could also work to control the humidity of the whole tent or room with a humidifier. She spent less than 4 days in the germination stage and graduated from seedling status on the 11th day from seed. The seedling stage is a balance between the calcium needs of the coco and the low EC tolerance of the seedlings. I use 23-watt CFLs (100-watt equivalent) during the seedling stage and each seedling gets their own. As a foliar application, the seedlings can handle a full-strength dose of CalMag. That is 5ml of General Hydroponics Calimagic per gallon. Clearly, cannabis plants enjoy increased parts per million as they grow. Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. Buffering the coco allows you to satisfy the majority of the cation exchange sites. While hydro and coco growers should aim for 5.8pH, or at least maintain pH around 5.5-6.1. However, if you follow the high frequency fertigation which we recommend (See “How to Water Cannabis in Coco”), the plants will produce sufficient humidity once they get into their final containers. But most growers will rarely exceed 1.4, even for huge plants. Be sure to follow the growth and development of your plant to determine how to care for it. On the other hand, adding too much can prevent the plant from absorbing water. If your starting water ppm is too low it causes the ph in the run off to go down. For soil growers a pH of 6.0-6.5 is perfect. The seedling is in its first container with coco/perlite. The Coco for Cannabis Nutrient Schedule is based on the General Hydroponics Flora Series Line. And understand your medium, some like more of one thing than others (coco usually likes more calcium than other mediums), and if you're in something like ffof you'll just be supplemental feeding at extremely low ppms. I start the lights about 4 inches from the plants when I first turn them on and move them to around 2 inches after the first set of true leaves have developed. In coco, the best results come from small containers with frequent watering. I like to have the light-off period occur during the daytime rather than at night because this makes it easier to maintain a consistent climate. This is too strong for the initial fertigations and portions of the water should be diluted to reach the target EC for each fertigation event. However, you cannot simply increase the dose. During vegetative growth we recommend keeping RH 60-75% (See, “The Best Environment for Growing Cannabis”). You are responsible for knowing and following the local laws that pertain to cannabis cultivation, possession, and use. This tutorial covers the roughly two-week period of the seedling stage. My tap water is PH 7.5 reading 199PPM. This will limit the plants ability to sustain optimal photosynthesis and growth. PPM, TDS, and EC in 30 Seconds PPM stands for Parts Per Million, a measure of concentration. Calcium deficiency is the most common problem that you may encounter. If everything goes well, you should reach this point about 2 weeks from seed. Coco is an inert medium, therefore, the plant only receives nutrients if we provide it with the irrigation water. (also a calculator on Canna site) You can just reduce EC/ppm a bit in the orange case, the blue are good for all the cycle, coco increase the salt in a way (built up). There's no need to use CalMag though, especially not the Mg if you're using proper (complete) nutrients already . Second fertigation is Seedling Blend EC 904, pH 6.3, Plant has two nodes. Therefore, if the pH is outside the target range, it is best to pour that water back and start again. If Your Coco Nutrients Don’t Contain This, They Might Starve To Death… As we discussed, until now, because coco binds to calcium and magnesium, you had to risk starving your plants of these critical nutrients… Many growers tried adding extra Ca and Mg using cal-mag supplements… but it’s hard to dial in the ratios just right… If you can buy filtered or RO try that. We do not accept sponsorship or advertising and will not recommend any product that we would not buy for ourselves. Relative humidity (RH) is always important to control because it affects transpiration. The plants respond so fast in the coco. They were growing way faster as in normal soil,i use coco fertilizers. When seeds first sprout, they use energy that is stored in the seed for their initial growth and development. The coco buffers 100-150ppm nutrient water just right. According to growpotcheaply.com and his feed schedule, he is recommending : Days 1-7 .6ec -- 300PPM As I explain in our article, “Transplanting Cannabis Plants: Why, When & How”, there are significant benefits to starting plants in small containers. However, I will be diluting the solution for each fertigation event and the dilution will slightly raise the pH of the solution. Plants can only perform photosynthesis when they have access to micro and macro nutrients. A few small issues but nothing they can't bounce back from. As we explain in our tutorial, "Germinating Cannabis Seeds - a Step-by-Step Guide", the seeds should be germinated in the dark to protect the young root from light. Copyright © 2020 Coco For Cannabis Inc All Rights Reserved, How To Grow Cannabis Seedlings in Coco Coir, Germinating Cannabis Seeds - a Step-by-Step Guide, "Transplanting Cannabis Plants: Why, When & How, Flush down the EC before adding seedlings, Create the right humidity and temperature for seedlings, Start fertigation (adding fertilizers to the water) 24 hours after the cotyledons open, Dilute the solution to your daily EC targets. My plants are on day 14 and they are coming along pretty good. GMO wrote:Hey dude couple things; TDS/PPM conversions to EC have massive variation from like 0.5 x up to like 1.2x PPM to EC depending.... so talking in PPM ive read that coco wants between 150-350ppm of just Calcium to fore fill the CEC requirement of the medium and leave enough for plants to have access to.... which is where the calmag buffering usually comes into play a pre … Our growing system is scientifically calibrated to provide the ideal nutrients at the right time. Young seedlings have underdeveloped leaves that cannot yet process high levels of light energy. Since the plants are small, you can maintain high RH with the use of a humidity dome. If you have a lux meter or quantum meter, you will want to keep your seedlings between 8000 – 20,000 lux or 100 – 300 umols PPFD. For a better experience, please enable JavaScript in your browser before proceeding. You must log in or register to reply here. During the seedling stage in coco, I keep the pH of my inflow between 6.2 and 6.4 because this improves calcium solubility during this sensitive time. Seed placed between wet paper towels in sealed container, Seed with tail transferred to Jiffy Pellet, Root Emerges, Jiffy Pellet transferred to seedling pot with pre-fertigated coco/perlite: Coco for Cannabis Seedling Blend: EC 400, pH 6.3, Fertigate twice: #1 EC 459, pH 6.23; #2 EC 464, pH 6.3, Fertigate twice: #1 EC 544, pH 6.1; #2 EC 612, pH 6.0, Fertigate twice: #1 EC 702, pH 6.2; #2 EC 772, pH 5.9, Plant has two nodes working on third. Therefore, I set the pH of the initial gallon to be 6.0 or 6.1. If a little heat is needed, then you can use a seedling heat mat below your humidity dome. She is a good model if your seedling suffers any CalMag issues. Be sure to see our tutorial, “EC/PPM Targets for Fertigating Cannabis”. In this tutorial, we walk you through everything you need to know and do to grow cannabis seedlings in coco coir. By the third fertigation, you can start to raise the inflow EC by 75-100 points at each event, as I show in the example timelines below. You can do this at up to every other fertigation depending on need. Buffering with a strong dose of CalMag prior to using the coco allows you to provide relatively little CalMag during the seedling stage of the grow. The products that we recommend are the actual products that we chose to purchase and use ourselves. However, if managed poorly, the plant can become stunted and never live up to its potential. Fertigate twice: #1 EC 987, pH 6.1; #2 EC 1050, pH 6.1, Fertgate twice: Full Strength Seedling Blend EC 1000, pH 6.4.
