When your little plants grow to three nodes they have graduated from seedling status and can be considered little plants. Without the right climate characteristics, the young plants will not live up to their full potential. We also have a live chat room, which is a great place to ask questions, get quick answers, and chat with fellow growers. If you use solo cups, be sure to cut numerous holes in the bottom of the cup to allow drainage. The seedling stage starts when the cotyledons (first round leaves) open, usually around 3-4 days after the seed gets wet. Vegged between 4-500, nothing burnt maybe a lil light! There are several key steps to follow to ensure that you mix solutions in the correct order and which have the correct Nutrient Element Ratio (NER), are the correct strength as measured by electrical conductivity (EC), and which have the correct pH. Therefore, if the pH is outside the target range, it is best to pour that water back and start again. (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). If your starting water ppm is too low it causes the ph in the run off to go down. During vegetative growth we recommend keeping RH 60-75% (See, “The Best Environment for Growing Cannabis”). My ph going in is also at 5.5. This is because young seedlings have underdeveloped roots and it can be difficult for them to pull adequate moisture from the soil. 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. 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. Because pH imbalance makes it difficult for the plant to absorb nutrients with its roots. Organic soils are too comple—x to be analyzed with ordinary PPM readers. If the parts per million reading is higher than 450 ppm, and/or the pH is wildly out of range, repeat the experiment to see if you can get runoff water that’s less than 450 ppm and within pH range. Please see our Product and Equipment Guide. Therefore, during the seedling stage, it is best to keep the intensity of light low. The Science and Practice of Growing Cannabis. As a foliar application, the seedlings can handle a full-strength dose of CalMag. Most seeds will not quite keep up with the pace that she set. I've been feeding them PH 5.8 tap water with weak nutes, rhizotonic and every 3rd feed 1ml of calmag. 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. 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. You are responsible for knowing and following the local laws that pertain to cannabis cultivation, possession, and use. So i finally got a PPM/EC Meter. 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. However, once the cotyledons open the plant will begin to fire up its ability to photosynthesize light energy. 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. We recommend growing sprouts first in a Rapid Rooter or Jiffy Pellet before transferring to coco. When the root of the sprout grows through the Rapid Rooter or Jiffy Pellet, the little plant should be transplanted into the first container, where it will live out its seedling days. Plants can only perform photosynthesis when they have access to micro and macro nutrients. PPM & EC. Therefore, I set the pH of the initial gallon to be 6.0 or 6.1. As soon as you see the first indications of seedling calcium deficiency begin treating them twice daily with a CalMag foliar spray. See the example timelines below. When I begin a grow, I prepare and buffer enough coco for the final containers. 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. Watering and feeding cannabis plants cultivated in coco coir is a relatively simple transition for hydroponics growers and organic growers. How to Prepare Coco for Seedlings. I have just purchased a PPM meter and wanted to know what PPM I should be using? Plant has three nodes. However, buffering solutions themselves have a high EC, and seedlings could be burned if they are placed in coco fresh from the buffering process. This practice helps to satisfy the coco’s craving for calcium, but it cheats the plant out of some other nutrients. 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. In coco, the best results come from small containers with frequent watering. Coco should never be allowed to get very dry. However, during the grow, more cation exchange sites are continuously exposed, which require additional CalMag. Seedlings in coco coir grow far faster if you start them off with seedling-strength nutrients from the beginning! Our Canna Coco feeding chart will show the optimal level of nutrients (A&B, Cannazyme, Rhizotonic, Boost, and PK 13/14). The cotyledons have been open for 24 hours, and. JavaScript is disabled. You are limited in the amount of CalMag that you can provide to seedlings because they cannot tolerate a solution with high Electrical Conductivity (EC). Before proceeding here, be sure to see my video and read our tutorial, “How to Mix Nutrient Solutions for Cannabis”. Especially with RO since coco is inert. Using EC and pH meters is almost mandatory if you choose this media, since you have to carefully check this values before watering your plants. Substitute CalMag Water for first fertigation EC 794. If plants are too cold or too hot, growth will be reduced as biological processes, especially photosynthesis, are directly influenced by temperature. Clearly, cannabis plants enjoy increased parts per million as they grow. 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. 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. Even if you are well prepared, you may encounter issues with calcium or magnesium deficiency during the seedling stage in plants grown in coco. Stretch was over early this week & went up to 700 ppm this nute batch. In most cases, they will be ready to be transplanted out of their seedling pots and into the next home. 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. 250-300ppm will be enough. A few small issues but nothing they can't bounce back from. Transplanting out of seedling containers can be tricky whether you use fabric seedling bags or plastic solo cups. This should not be a problem early on. Transplant to second container: End seedling stage. My plants are on day 14 and they are coming along pretty good. The seedling stage is one of the most sensitive periods of a plant’s life. Specifically, coco specific nutrient ranges are worthy of consideration. 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… Coco is an inert medium, therefore, the plant only receives nutrients if we provide it with the irrigation water. We have a wonderful community of growers and you are welcome to join! Before you use coco, it should be properly rinsed, buffered and mixed with perlite. I'm moving to Coco this week (got some beans germinating). However, if managed poorly, the plant can become stunted and never live up to its potential. 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. PPM Levels for Cannabis Plants. They were growing way faster as in normal soil,i use coco fertilizers. Growing weed in coco coir is a great way to to produce high quality marijuana for new and experienced growers alike. We advise strongly against placing small plants into large final containers. There's no need to use CalMag though, especially not the Mg if you're using proper (complete) nutrients already . 1 Like Botanicare (Post author) April 18, 2018 ... Ppm certainly can differ with each nutrient line, but I use a blend of Botanicare and Canna along with some other products and my ppm is rarely above 1200 even in late flower. But most growers will rarely exceed 1.4, even for huge plants. My tap water is PH 7.5 reading 199PPM. Why is pH important? Seedlings and clones in coco should be strong enough to handle a light breeze at this stage. then slowly taper off. When the root emerges, we recommend placing the plants into either fabric seedling bags or solo cups with prepared coco. As I explain in our article, “Transplanting Cannabis Plants: Why, When & How”, there are significant benefits to starting plants in small containers. The other 999 ml is water. When you click through our links and make purchases you are supporting our work! Using the watering syringe allows you to carefully water around the pellet or rooter and saturate the coco. Conversely, if the seedling gets too much light it can damage photosynthetic systems and other cellular components. 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). On the one hand, adding nutrients to the water helps the plant grow. Plants at different stages of growth will need different levels of EC. If you do encounter problems with Ca or Mg deficiency during the seedling stage, we have suggestions for you below. Second fertigation is Seedling Blend EC 904, pH 6.3, Plant has two nodes. To help with drainage and to encourage root growth it is best to avoid watering the top of the Rapid Rooter or Jiffy Pellet. The seedling stage is a balance between the calcium needs of the coco and the low EC tolerance of the seedlings. Be sure to see our tutorial, "Germinating Cannabis Seeds - a Step-by-Step Guide". Ph is also coming out around 6.9-7.0. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. Transplant to Second Container: End Seedling stage. But the most reliable methods, and most widely used, is EC. It is especially difficult to deal with CalMag problems during the seedling stage. Everything you read from people says to gradually increase every week until you're close to or over 1000ppm. PPM in 10 Seconds PPM is a measurement of nutrients in the soil or growing medium. 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). The products that we recommend are the actual products that we chose to purchase and use ourselves. Don't be afraid making seedling in coco, only avoiding over watering, let drying well the coco before new watering. I'm using a&b with cal-mag, plan on topping out at around 900 ppm mid-flower. Until plants get bigger and start drinking more, you may want to give just a small amount of water at a time in a circle around the plant. As the plants start maturing during the seedling stage, it is time to work your way through a transplant strategy. For complete instructions and photos of the process be sure to see "Transplanting Cannabis Plants: Why, When & How”. Cannabis enjoys 500-600 ppm after cloning, 800-900 ppm when vegetating, and 1000-1100 ppm when flowering.So knowing the mineral content of your water before mixing your nutes can avoid stressing you and your plants. I confirm that the EC is about 1000 and I measure and adjust the pH for the full gallon. These peat-based media provide a more stable buffer for germinating seeds and sprouts. Calcium and magnesium deficiencies are common problems with plants grown in coco. You can often observe this on the leaves of seedlings on the first two nodes. This may cause some plants to blow over if the stem is too weak. There is also TDS, and PPM, which can be used to measure the salt content of a solution. Be sure to see our tutorial, “How to Prepare and Buffer Coco Coir”. As you will see below, each grow and each plant are a little different. We recommend that you always use a transplant regime and never start seedlings in final containers. The humidity and temperature are very important during the early stages of growth with seedlings. I keep the bulk of the coco/perlite moist with CalMag Water in fabric pots until I need it. 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. Three to five times per day may sound like a lot of water, but with such frequent … 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. 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. The first couple of fertigations should be at an EC of only 400. “Blueberry Kush” from Grower’s Choice Seeds took a little longer to germinate and then suffered minor calcium deficiency as a seedling. The seedling stage runs until the plant has three true nodes (sets of serrated leaves). It is a great way to share your experience and ask questions along the way. That is 5ml of General Hydroponics Calimagic per gallon. However, it is best to avoid the problems in the first place by properly preparing your coco. 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. 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. Adding a wetting agent to the foliar solution is optional. Once the cultivator reduces the photoperiod to induce flowering, the plants will do their best at 1000-1100 PPM. She spent less than 4 days in the germination stage and graduated from seedling status on the 11th day from seed. Use this Canna Coco feed schedule and grow guide to grow killer marijuana in coco coir. Until the plant opens its leaves it is not capable of photosynthesis. 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! The coco buffers 100-150ppm nutrient water just right. 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. Soil – water with plain, pH’ed water at 6-7 pH, no nutrients , for the first 3 weeks or so – your plants will be able to live off the nutrients in the soil, and adding extra might be … Plants do not get their energy from fertilizers, rather they get energy from the light and capture it through photosynthesis. This will limit the plants ability to sustain optimal photosynthesis and growth. Relative humidity (RH) is always important to control because it affects transpiration. 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. 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. The following two timelines are offered to give an understanding of a specific application of the principles outlined in this tutorial. According to growpotcheaply.com and his feed schedule, he is recommending : Days 1-7 .6ec -- 300PPM We may receive a referral when you purchase products through our links. For a better experience, please enable JavaScript in your browser before proceeding. This flush is important because otherwise the residual high EC from the buffering process could burn your sensitive seedlings. For soil growers a pH of 6.0-6.5 is perfect. Small plants in big containers can take a long time to dry out. However, you can mix a smaller batch, just add enough CalMag so that the EC is 800. pH should be above 6.2. The Science and Practice of Growing Cannabis. 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”. When plants are still seedlings, the amounts needed for each fertigation event are very small. If symptoms deteriorate despite the foliar treatment, then you should substitute CalMag water in place of the regularly scheduled nutrient solution. You can do this at up to every other fertigation depending on need. Therefore, it is important to reduce the residual EC in the coco before transplanting the seedlings. During mid flowering stage, cannabis plants like a PPM around 1000. If you still have a dome or cup over your plants, they should be removed now, and a light breeze applied to the plants. For simple instructions and our explanation, be sure to see our tutorial, "Transplanting Cannabis Plants: Why, When & How”. 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. 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. During the seedling stage it is particularly important to provide nutrient solution that is the correct strength as measured by Electrical Conductivity (EC). I grow in coco so I can see how they react within a day or 2 normally. It took her a total of 14 days from seed to graduate the seedling stage. Buffering your coco is critical to help ensure a smooth seedling stage. During the seedling stage the relative humidity should remain high, 65 – 80% and the temperature should be moderate, 72-79f (22-26c). 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. If everything goes well, you should reach this point about 2 weeks from seed. So there you have it. Roots Out from the bottom of seedling Bag! 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. Therefore, you should save the high-powered grow lights to use later and use low wattage fluorescent or LED lights for cannabis seedlings. Cooling is more difficult, so be aware that most of the heat comes from the lights and be sure that the lights get good ventilation even if you are trapping the humidity around the plants. At mid flowering about 1 ml of a 1 liter watering can of water is nutrients. Easy to follow instructions to produce great weed plants for novice growers and experts alike. Try using a lower ppm water to start off when making your nutrient solution. Seedlings are more sensitive than older plants and it is worth the effort to maintain their temperature in a narrower range. The plants respond so fast in the coco. 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 use a giant 60ml oral syringe to fertigate my little seedlings. However, once the root is in media and the head emerges from the Rapid Rooter or Jiffy Pellet, the lights should come on. I need to understand how this PPM thing works. However, it may take longer, so be patient with your little seedlings and listen to what they tell you. 18/6 refers to a light schedule where the lights are on for 18 hours and off for 6. If a little heat is needed, then you can use a seedling heat mat below your humidity dome. If you are using a different line, be sure to follow the ratios provided by the supplier for the base nutrients. However, you cannot simply increase the dose. If the seedling is not getting enough light it will stretch and quickly grow vertically. Hence, this tutorial covers roughly days 3-15 from seed. I have some plants in coco coir and first they looked damn good in the seedlings/earlyveg/veg stage. However, buffering solutions themselves have a high EC, and seedlings could be burned if they are placed in coco fresh from the buffering process. While hydro and coco growers should aim for 5.8pH, or at least maintain pH around 5.5-6.1. I leave my CFL lights on 24/0 (full time) until the cotyledons open, at which point I begin 18/6 lighting. Decisions to grow cannabis should be made in consultation with a lawyer or qualified legal advisor. The optimal pH and EC values for cannabis cultivation are contingent upon three factors, the growing substrate, nutrients and water. It’s a little intimidating. 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. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. During the flower stage, optimum parts per million rises to 1000-1100. Gradually increasing the EC in this fashion allows plants to tolerate and then thrive under higher EC conditions where it is best to keep them through the rest of the grow. You may need to either heat or cool your seedlings in order to achieve the correct temperature. PPM Levels The information on cocoforcannabis.com should not be considered as financial, legal, or medical advice. 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. “Blueberry” from Seedsman was a fast-growing seedling. The temperature that plants grow in has a large influence on the photosynthetic efficiency and respiration. Very young seedlings or clones will appreciate receiving water with a PPM reading of 500-600 PPM. CalMag has a strong impact on EC so when seedlings do suffer Ca or Mg deficiencies, they can be tough to correct. The first sign of calcium deficiency is a slight twisting of the leaves. I confirm that the pH is 6.2-6.4 before applying the solution to the coco. If it's going up your starting water quality is too high in dissolved minerals. 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. 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. For simplicity we will simply use “Soil” to stand for all three. I use 23-watt CFLs (100-watt equivalent) during the seedling stage and each seedling gets their own. However, I will be diluting the solution for each fertigation event and the dilution will slightly raise the pH of the solution. We do not accept sponsorship or advertising and will not recommend any product that we would not buy for ourselves. Be sure to see our tutorial, “EC/PPM Targets for Fertigating Cannabis”. Around 400. 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. The seedling is in its first container with coco/perlite. yep your good, 550-600 ppm by end of veg 900-1100 ( depending on amount of light and if there is co2 enrichment) by mid flower. This may seem like progress, but it produces a weak plant structure and slows overall growth. Thanks again!!! As a result, seedlings should be watered once or twice per day once they are placed in their seedling pots with coco/perlite. It is often necessary to raise the RH during the seedling stage. This means that a 15-25 watt fluorescent or LED propagation light is perfect for seedlings. Whether a cannabis plant is planted in soil, coco, or hydro, pH levels need to be maintained to optimal levels. Seedlings must be started with a nutrient solution that is very low strength as measured by Electrical Conductivity (EC). When seeds first sprout, they use energy that is stored in the seed for their initial growth and development. Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. 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. I mix one gallon of full strength seedling blend solution prior to the first fertigation. Caring for seedlings in coco coir can be tricky, but we have you covered. If you can buy filtered or RO try that. This tutorial covers the roughly two-week period of the seedling stage. Buffering the coco allows you to satisfy the majority of the cation exchange sites. 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. 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. This makes the match simple. 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. If you properly prepare and buffer the coco for the next transplant, then you should not continue to suffer issues and can return to normal management practices. For those crucial first 3 days, be sure to see our tutorial "Germinating Cannabis Seeds - a Step-by-Step Guide". Thanks for the good informations. 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. Our growing system is scientifically calibrated to provide the ideal nutrients at the right time. On the other hand, adding too much can prevent the plant from absorbing water.
