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.

CLEAN COCO cubes contain a compressed brick of pure coir, packaged in a biodegradable mesh that allows root penetration. These are an ideal substitute for rock wool cultivation and may require less frequent nutrient feeds. Similar to grow bags, simply hydrate the cubes and place seeds, rooted cuttings or small plants in the pre-drilled hole. These are ideal for smaller plants (less than 24” height) in drip irrigation and can be easily composted after crop harvest. While the cubes can be used in food irrigation, the product is best suited for drip irrigation.

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.

When handling a new substrate, it is helpful to identify the moisture characteristics before planting. Perform a simple on-site test by flling a container with the coir substrate, fully saturate with water, take a moisture reading, allow to drain for up to 24 hours, take another reading to obtain the feld capacity moisture, and a third reading when minimal moisture remains. These three readings will provide the VWC for saturation point, feld capacity, and wilting point. VWC above 60% is likely saturated, and below 30% is likely the permanent wilting point.

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.

Irrigation timing and volume will largely depend on environmental conditions and irrigation system components. A general rule of thumb is to apply 10-15% more water than the container will hold. This allows for some runoff with each irrigation and reduces the potential for salt accumulation. The fow rate must be adjusted to allow thorough media saturation but avoid overfow of the container.

Today we’re going to talk about growing cannabis in coco coir slabs. It’s quite a simple growth method and has nothing to do with hydroponics; in hydroponics you need to strictly control your plants, their roots, the water temperature, and many more things.

Something that you’re going to need to stay on top of is the height of your plants as they grow quire fast in slabs; the best way to control the height of your plants and the weight of the buds is by using a SCRoG mesh once flowering begins; you’ll manage to keep the height under control and increase the weight of your yield even more.

Here’s a short list of the things you’ll need to begin growing in coco coir slabs:
