Guideline on usage of Coco Grow Bags

The following guideline & usage instructions are based on extensive research carried out on our products under different growing conditions & also on valuable information shared by professional growers, who have been using our Grow bags for the past couple of years.

It is very important to understand that these guidelines & usage instructions dose not specifically refers to your case & is compiled in general. These guidelines & usage instructions may differ depending on your growing application, crop, green house & the location (climatic condition).

Adopting a Fertilizer plan

It is of utmost importance to know the optimum level of nutrients required for your crop before analyzing the medium. The level of chemical & nutrients vary from crop to crop. The next step would be the identification of chemical levels present in the medium. This will enable the grower to balance the addition of neutrinos & also reduce the levels of adverse substances. Further you should analyze the water used in the green house, to find the composition of same.

First take several Grow Bags and hydrate with clean water using the Drips till the slabs are fully saturated & stop watering just as water tries to come out of the cut plant holes and let for 12 hours

Commence draining the after 12 hours while adding fresh water

Collect a water sample at the end of the draining process.

Make analysis from this water sample to ascertain the chemical composition, with this analysis a fertilizing plan should be made.

It is important to note that Coco materials contain high levels of Potassium & is low in Calcium. So when you are calculating your fertilizer plan, take out the Potassium & replace with Calcium Nitrate. Apart from the replacement of Calcium Nitrate for Potassium, a further percentage of Calcium Nitrate should be added according to your crop’s requirement. (Differs in case of Buffered Materials)


After taking the Grow Bags out from their palletized packed form, plant holes should be cut (If not prepared by us as per your request).

Grow bag should be handled carefully while un loading to prevent the slabs from breaking. If the slabs are damaged the expansion after watering will be uneven.

The Grow Bags should be placed on level profile within the green house.

Drip lines should be inserted to the Grow Bags depending on the number of plants planned to be planted per Grow Bag. (Never use a water hose to water as it will damage the structure of the Grow Bag).

Water the Grow Bags using the Drips till the slabs are fully saturated & stop watering just as water tries to come out of the cut plant holes & let for 12 hours

Make adequate Drain holes in the bags to let the water out (Drain holes should be made between every plant hole & at both ends of the bag) & let the added water drain from the bags

Add the fertilizer plan through the Drip till the slabs are fully saturated (approximately 1 liter per plant).

Now you can plant your crop in the Grow Bags

After Planting

Frequent analysis should be performed to ascertain the levels of neutrinos available to the plant.

Based on this analysis you should adjust your fertilizer plan.

After planting your crop give frequent water (short shots), so you will prevent drying out of the media within the grow bag.

If you require controlling the plant growth, you can stop with dripping water for a couple of days, when plants are fully rooted in. However you should be mindful not to let the media dry out.

Close observation on the plant’s growth & by monitoring areas such as rooting, leafs, stem strength & yielding process, will give you an early indication regarding the plant’s growth.


The watering process of Coco Grow Bags needs to be properly learnt in order to have better results. Coco material is capable of holding higher levels of water than most parallel growing medium.

To get the most efficiency in watering, water should be dripped at a low phase for a longer duration of time to optimize the absorbency to the material.

The level of water required to be dripped is calculated on the consumption level of your crop & the temperature & humidity level within your green house.

Due to the distinct physical structure of Coco material, water absorbency by way of capillary actions delivers the water within the medium at a steady phase.

Make sure that you don’t over drip the bags as too much of water will drain away the nutrients & the fine partials in the medium. If over watering continues, it might even lead to mutilation & decay of roots.

The other disadvantage in over watering is that the material at the lower level of the bag will form into a slug, an area without any air porosity, make the roots of the plant draw towards the surface of the bag in search for air, making the plant unstable.

The root development in Coco material is rapid. Watering should be continued until the roots are deeply rooted in the bag. Once the roots are deeply rooted an interval in watering will enable the roots to establish within the grow bag.

As the plant begins to grow in the bag till the yield is harvested the watering level needs to be adjusted as per the plant’s water consumption & the ambient temperature in your Green house.
