growing cannabis in coco

Look for any color changes in the leaves, if the first few leaves have turned yellow then it means Nitrogen deficiency (sigh of reduced chlorophyll production), so make appropriate arrangements for proper nutrient management and do not go low or higher than optimal.

Considered as a regularly growing plant, cannabis are provided with 12-12 lighting duration (12 hrs light, 12 hrs darkness).

Increase the EC of the solution by parts of 80-100 every time. At the end of seedling the nutrient solution must be of its full strength around 1000EC.

The typical coco coir available on the market are pre-washed, buffered, hydrated and ready to use right out of the bag.

Stage- 3- Transplant

Place a thermometer or hygrometer to check for simultaneous change in temperature and air moisture.

The seedling in the coco/perlite substrate should be watered once or twice per day until 20% runoff from bottom. Coco must not be let to dry and be frequently wetted.

Furnish other fertilizers and grow amendments to enrich the nutrient availability.

Vegetative phase

Marijuana requires highest aeration compared to other weeds. Mixing grow supplements like perlite and vermiculture improves water intake and encourages strong root growth.

Coco coir are commercially available as bagged loose coco coir and compresses blocks and also ready-to-use cultivation blocks .

Neutral pH. Its pH is close to neutral (6), so coir can be used straightaway. Peat is acidic (as low as 3-4) and needs to be treated with lime before use. This neutrality is good because it allows the user to add the nutrient mix of their choosing.

If you’re just beginning to grow cannabis legally, you’ll want to grow it correctly. While we won’t get into the day-to-day details of cannabis production here, we will explain how to get your cannabis crop off to the best start possible. It all starts with your growing media (and we know growing media). Specifically, one growing media of choice for many growers is coco coir.

Over the last decade cannabis production has come out of the closet, quite literally. The first person I knew to have grown his own cannabis (or marijuana or pot or whichever name you prefer to call it) grew several pots of it in his bedroom closet, hidden away from his parents. And while some folks may grow cannabis in places unseen by parental and other authorities’ eyes, at-home and/or commercial legal cannabis production is now A-OK in 18 states and Washington, D.C. with more coming on board every year.

What Is Coco Coir?

Packed with nutrients and biostimulants. It’s a formerly living thing, so it comes packed with its own set of nutrients, such as potassium, iron, manganese and zinc, to name a few. Again, you should take this into account when considering what nutrients to apply. It also contains biostimulants, which act as growth enhancers and give whatever is planted in it a boost.

Our Cocodelphia is also continually tested for heavy metals, and each test result comes back clean. Don’t just take our word for it! Our customers have done their own testing and tell us it’s the cleanest heavy metal-free coir for cannabis production around. And for you professional cannabis growers out there, you know cannabis that fails a heavy metal test means a lost crop and lost profits.

Focus on a proactive rather than a reactive approach. Irrigation should be timed properly to allow for consistent moisture levels and nutrient delivery without overwatering or overfeeding. Before planning irrigation, use the test detailed above to identify the saturation range to the wilting point.

In order to properly manage substrate moisture and nutrient availability in coco coir, it is important to understand a few key terms. Saturation describes the total volume of water a substrate can hold by percent of substrate weight, or the water holding capacity (WHC). Field capacity describes the available water content in a substrate after excess water has drained. Permanent wilting point occurs when there is no remaining moisture available for plants to extract from the substrate.



Substrates like coco coir that consist of high organic matter will decompose during the production cycle, leading to changes in the air to water ratio. This highlights the importance of consistent moisture monitoring and irrigation adjustments based on moisture readings. A soil moisture sensor that measures volume water content (VWC, %) is a simple tool that can be placed into the root zone to monitor moisture.

The frst irrigation typically starts one hour after lights on or sunrise and ends one hour before lights off or sunset. Irrigations can be scheduled hourly or more frequently, depending on conditions. Excessive dry down between irrigations may increase soluble salt concentration and contribute to hydrophobic properties of the substrate. Clear water fushing of the coir substrate between nutrient feedings is an effective procedure to reduce and prevent salt buildup.

CLEAN COCO grow bags contain a compressed brick of pure coco coir in a disposable, perforated bag that is made of recyclable UV-protected plastic. Simply hydrate the brick and transplant your rooted clone or young vegetative plant into a 1-gallon or 3-gallon bag. This is an ideal option for large scale cultivation facilities with automated irrigation, as well as any grower looking to cut down on labor expenditure with pot flling and transplanting.
