ppm for seedlings in coco

My ph going in is also at 5.5. 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). 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. When I begin a grow, I prepare and buffer enough coco for the final containers. Calcium deficiency is the most common problem that you may encounter. The fertilizers that we provide allow the plant to conduct photosynthesis efficiently, but they are not “food” that plants “eat” for energy. The plants respond so fast in the coco. If 1 PPM is 1ml per 1000 liters, a PPM of 1000 means 1ml per 1 liter. You may need to either heat or cool your seedlings in order to achieve the correct temperature. On the other hand, adding too much can prevent the plant from absorbing water. This should not be a problem early on. As the plants start maturing during the seedling stage, it is time to work your way through a transplant strategy. Around 400. 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. We have a wonderful community of growers and you are welcome to join! Roots Out from the bottom of seedling Bag! I use 23-watt CFLs (100-watt equivalent) during the seedling stage and each seedling gets their own. I leave my CFL lights on 24/0 (full time) until the cotyledons open, at which point I begin 18/6 lighting. Whether a cannabis plant is planted in soil, coco, or hydro, pH levels need to be maintained to optimal levels. Depending on the number of plants that you are growing, one or two gallons of full strength solution should be sufficient for the full week. 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. Caring for seedlings in coco coir can be tricky, but we have you covered. We recommend that you always use a transplant regime and never start seedlings in final containers. If everything goes well, you should reach this point about 2 weeks from seed. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum. 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. In this tutorial, we walk you through everything you need to know and do to grow cannabis seedlings in coco coir. Thanks for the good informations. 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. This flush is important because otherwise the residual high EC from the buffering process could burn your sensitive seedlings. Our Canna Coco feeding chart will show the optimal level of nutrients (A&B, Cannazyme, Rhizotonic, Boost, and PK 13/14). Without the right climate characteristics, the young plants will not live up to their full potential. 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. During vegetative growth we recommend keeping RH 60-75% (See, “The Best Environment for Growing Cannabis”). It is often necessary to raise the RH during the seedling stage. 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. 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. 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. For those crucial first 3 days, be sure to see our tutorial "Germinating Cannabis Seeds - a Step-by-Step Guide". Use this Canna Coco feed schedule and grow guide to grow killer marijuana in coco coir. This allows you complete control of their RH as long as they fit in the dome and you use a hygrometer. My plants are on day 14 and they are coming along pretty good. 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. If symptoms deteriorate despite the foliar treatment, then you should substitute CalMag water in place of the regularly scheduled nutrient solution. However, it is best to avoid the problems in the first place by properly preparing your coco. There's no need to use CalMag though, especially not the Mg if you're using proper (complete) nutrients already . The Rapid Rooter or Jiffy Pellet will be in the center of the seedling pot. Transplanting out of seedling containers can be tricky whether you use fabric seedling bags or plastic solo cups. I have some plants in coco coir and first they looked damn good in the seedlings/earlyveg/veg stage. 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. But the most reliable methods, and most widely used, is EC. This is the main revenue stream that keeps Coco for Cannabis up and running! The first sign of calcium deficiency is a slight twisting of the leaves. PPM in 10 Seconds PPM is a measurement of nutrients in the soil or growing medium. Sometimes the edges of the leaves look wavy as a result. This makes it easy to apply water slowly and carefully. 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. Be sure to see our tutorial, "Germinating Cannabis Seeds - a Step-by-Step Guide". 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. Very young seedlings or clones will appreciate receiving water with a PPM reading of 500-600 PPM. It is especially difficult to deal with CalMag problems during the seedling stage. 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! If it's going up your starting water quality is too high in dissolved minerals. Especially with RO since coco is inert. This is because the coco is taking the Ca and Mg from the nutrient solution. Fertigate twice: #1 EC 976, pH 6.0; #2 EC 1012 (Full strength), pH 6.2. The other 999 ml is water. Decisions to use cannabis should be made in consultation with your doctor or medical professional. 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”. Before proceeding here, be sure to see my video and read our tutorial, “How to Mix Nutrient Solutions for Cannabis”. Easy to follow instructions to produce great weed plants for novice growers and experts alike. I'm using a&b with cal-mag, plan on topping out at around 900 ppm mid-flower. During mid flowering stage, cannabis plants like a PPM around 1000. Specifically, coco specific nutrient ranges are worthy of consideration. However, during the seedling stage it is helpful to keep a somewhat higher RH. 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. Before you use coco, it should be properly rinsed, buffered and mixed with perlite. We cover how to prepare coco for seedlings, the best containers for seedlings in coco, relative humidity for cannabis seedlings, temperature for cannabis seedlings, light for cannabis seedlings, fertilizers for cannabis seedlings, how to water seedlings in coco coir, and how to treat seedlings with calcium deficiency. However, it may take longer, so be patient with your little seedlings and listen to what they tell you. To help with drainage and to encourage root growth it is best to avoid watering the top of the Rapid Rooter or Jiffy Pellet. Vegged between 4-500, nothing burnt maybe a lil light! Watering and feeding cannabis plants cultivated in coco coir is a relatively simple transition for hydroponics growers and organic growers. 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. Plants can only perform photosynthesis when they have access to micro and macro nutrients. During the seedling stage the relative humidity should remain high, 65 – 80% and the temperature should be moderate, 72-79f (22-26c). Please see our Product and Equipment Guide. Try using a lower ppm water to start off when making your nutrient solution. Don't be afraid making seedling in coco, only avoiding over watering, let drying well the coco before new watering. The seedling stage starts when the cotyledons (first round leaves) open, usually around 3-4 days after the seed gets wet. When plants are still seedlings, the amounts needed for each fertigation event are very small. She spent less than 4 days in the germination stage and graduated from seedling status on the 11th day from seed. 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. How to Prepare Coco for Seedlings. You could also work to control the humidity of the whole tent or room with a humidifier. I use a giant 60ml oral syringe to fertigate my little seedlings. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . Growing weed in coco coir is a great way to to produce high quality marijuana for new and experienced growers alike. 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). Until the plant opens its leaves it is not capable of photosynthesis. Be sure to follow the growth and development of your plant to determine how to care for it. We recommend growing sprouts first in a Rapid Rooter or Jiffy Pellet before transferring to coco. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. For simplicity we will simply use “Soil” to stand for all three. If symptoms progress, you will notice brown spots form on the leaves. I'm moving to Coco this week (got some beans germinating). Stretch was over early this week & went up to 700 ppm this nute batch. If a little heat is needed, then you can use a seedling heat mat below your humidity dome. Seedlings and clones in coco should be strong enough to handle a light breeze at this stage. The products that we recommend are the actual products that we chose to purchase and use ourselves. However, you cannot simply increase the dose. The first couple of fertigations should be at an EC of only 400. However, both hydroponic and soil pH levels should stay within the same optimal range of 5.5-6.0 pH. If you do encounter problems with Ca or Mg deficiency during the seedling stage, we have suggestions for you below. You must log in or register to reply here. Keeping higher relative humidity reduces the stress on seedlings. For complete instructions and photos of the process be sure to see "Transplanting Cannabis Plants: Why, When & How”. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. However, if managed poorly, the plant can become stunted and never live up to its potential. Plant has three nodes. Plants at different stages of growth will need different levels of EC. The humidity and temperature are very important during the early stages of growth with seedlings. We advise strongly against placing small plants into large final containers. This will limit the plants ability to sustain optimal photosynthesis and growth. Ideally, you should plan to water your cannabis plants in coco 3-5 times per day during the flowering period. However, I will be diluting the solution for each fertigation event and the dilution will slightly raise the pH of the solution. At mid flowering about 1 ml of a 1 liter watering can of water is nutrients. 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. Adding a wetting agent to the foliar solution is optional. 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. You can often observe this on the leaves of seedlings on the first two nodes. 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. There is also TDS, and PPM, which can be used to measure the salt content of a solution. Second fertigation is Seedling Blend EC 904, pH 6.3, Plant has two nodes. In the end you just have to understand and read your plants to know if they want more or less. As a result, seedlings should be watered once or twice per day once they are placed in their seedling pots with coco/perlite. For a better experience, please enable JavaScript in your browser before proceeding. Seedlings are more sensitive than older plants and it is worth the effort to maintain their temperature in a narrower range. You can use various strategies to achieve the correct RH. 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. Continue the foliar treatment until the seedlings are on the full-strength seedling blend. We also have a live chat room, which is a great place to ask questions, get quick answers, and chat with fellow growers. So there you have it. I mix one gallon of full strength seedling blend solution prior to the first fertigation. 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. If you still have a dome or cup over your plants, they should be removed now, and a light breeze applied to the plants. When the root emerges, we recommend placing the plants into either fabric seedling bags or solo cups with prepared coco. then slowly taper off. If you can buy filtered or RO try that. I need to understand how this PPM thing works. 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. This may seem like progress, but it produces a weak plant structure and slows overall growth. The buffering process is crucial to prepare the coco for plants, and especially seedlings. 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. They were growing way faster as in normal soil,i use coco fertilizers. Be sure to see our article, “Why and How to Use CalMag in Coco”. In coco, the best results come from small containers with frequent watering. I have just purchased a PPM meter and wanted to know what PPM I should be using? 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. Plants do not get their energy from fertilizers, rather they get energy from the light and capture it through photosynthesis. When you click through our links and make purchases you are supporting our work! 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. PPM & EC. Calcium and magnesium deficiencies are common problems with plants grown in coco. We welcome all growers who want to learn, share and grow together! However, during the grow, more cation exchange sites are continuously exposed, which require additional CalMag. However, buffering solutions themselves have a high EC, and seedlings could be burned if they are placed in coco fresh from the buffering process. Why is pH important? 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. Substitute CalMag Water for first fertigation EC 794. Transplant to second container: End seedling stage. Be sure to see our tutorial, “How to Prepare and Buffer Coco Coir”. Organic soils are too comple—x to be analyzed with ordinary PPM readers. If your starting water ppm is too low it causes the ph in the run off to go down. 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. Start with daily watering, however by the third or fourth day of fertigation, you can increase frequency to twice daily. Therefore, if the pH is outside the target range, it is best to pour that water back and start again. As an Amazon Associate, we earn from qualifying purchases. 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. 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. I've been feeding them PH 5.8 tap water with weak nutes, rhizotonic and every 3rd feed 1ml of calmag. 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. Using the watering syringe allows you to carefully water around the pellet or rooter and saturate the coco. The coco buffers 100-150ppm nutrient water just right. Be sure to see our video and tutorial for “How to Prepare and Buffer Coco Coir”. 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. Therefore, it is best to avoid any fertilizers and keep germinating seeds and sprouts in low EC water. Small plants in big containers can take a long time to dry out. The optimal pH and EC values for cannabis cultivation are contingent upon three factors, the growing substrate, nutrients and water. The cotyledons have been open for 24 hours, and. In most cases, they will be ready to be transplanted out of their seedling pots and into the next home. This practice helps to satisfy the coco’s craving for calcium, but it cheats the plant out of some other nutrients. Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. 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. 18/6 refers to a light schedule where the lights are on for 18 hours and off for 6. 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. That is 5ml of General Hydroponics Calimagic per gallon. But most growers will rarely exceed 1.4, even for huge plants. However, once the cotyledons open the plant will begin to fire up its ability to photosynthesize light energy. Therefore, you should save the high-powered grow lights to use later and use low wattage fluorescent or LED lights for cannabis seedlings. Plant has three nodes. It’s a little intimidating. This means that a 15-25 watt fluorescent or LED propagation light is perfect for seedlings. Hence, this tutorial covers roughly days 3-15 from seed. 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. When your little plants grow to three nodes they have graduated from seedling status and can be considered little plants. 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. Our growing system is scientifically calibrated to provide the ideal nutrients at the right time. Thanks again!!! This tutorial covers the roughly two-week period of the seedling stage. However, once the root is in media and the head emerges from the Rapid Rooter or Jiffy Pellet, the lights should come on. A few small issues but nothing they can't bounce back from. 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.
