Pelemix- coco Coir Substrates Professionals


Growing tomatoes in grow bags is an  ideal solution for Tomatoes growth.
Pelemix offers a big variaty of sizes and coir mixes for growing tomatoes in grow bags.

The size of tomato grow bag and coir mix should be selected according to climate, irrigation system, irrigation method and duration of growing period. 

Production process is carefully monitored by our QC system and our R&D center  is equipped with our own lab. 
Pelemix in-house team of agronomists  keeps a field research process to develop new products to meet the high yield potential of greenhouse crops and grower’s preferences.

Tomato Grow Bags Types


Tomato grow bags are coco coir compressed slabs, wrapped by a polyethylene white/black bag.

Available dimensions are from 8 cm up to 16 cm high and from 10 cm up to 40 cm wide. The length is up to 120 cm.

Planting and drainage holes can be ordered in advance or easily made at the plot.

Coco coir tomato grow bags enable the grower full control over the crop.

Coco coir hanging tomato bags are easy to handle in the greenhouse and are being used as a complete growing system.

Coco Coir Material Types

16 mm

16mm Cocopeat is one of Pelemix’s leading products and it is recommended for use in hot climate regions (Such as Spain, Mexico, South-Africa, Australia e.t.c). 16mm sieving is exceptional in terms of its air-water ratio. Although the Cocopeat has adequate water capacity it also maintains a balanced air capacity as well. Pelemix’s pressing technology guarantees even distribution of the different segmentations inside the grow bag. By doing so, Pelemix creates a uniform grow bag that allows air and water to be distributed equally across the growing media.

P.L.F Coco Coir

The P.L.F. Cocopeat is a combination of crush coco and 16 mmcoco pith materials. The presence of crushed coco provides a more drainable medium and therefore is more suitable for regions with both hot and cold growing periods (Such as U.S.A. and Turkey). Here, once again, Pelemix’s pressing technology guarantees uniform distribution of the two Coir types inside the tomato grow bag. Combination of the two Coir types guarantees a balanced air and water distribution along with faster drainage.

Crush Pro

This Combination of  3/4” cocopeat and  Crush, provides a more drainable growing media. It is suitable for climates with cold winters and hot summers. It is perfect for growers who are interested in applying a large number of irrigation cycles in all seasons.


Placing Growbags on a Gutter

It is important to place the growbags on a gutter or any other form of draining system. It will guarantee effective drainage of the growbags and growing structure (Greenhouse, Net-house etc.).

If the plot surface is covered, it will help controlling weeds and will slow the development of some insects.

Expantion of Growbags

Expand the Growbags with short irrigation cycles. Allow 20 minutes between cycles. Short irrigation cycles will prevent unnecessary drainage during expanding (If growbags were not bought with draining holes, drainage is not a big issue). 

The size of the expanded tomato grow bag is determined by the size of the plastic bag. Make sure the growbag gets enough water to expand to its final volume. 

Arrow Drippers and Draining Holes

Arrow drippers are highly recommended but a dripline is also possible. 

Make at least 3 draining holes in each side of the growbag. Make the hole at height 0 on the side of the growbag (Only if growbags were not bought with draining holes).

Pelemix Grow Bags are provided with planting and drainage holes in accordance to the client’s request. 

Calcium Nitrate treatment

Calcium Nitrate treatment- in order to improve nutrients balance at the time of planting, it is recommended to apply CaNO3 in the amount of 2 kg per 1 cubic meter of coir. For example, in 15cm by 12cm by 100cm Growbags, it’s 2 kg of CaNO3 per 55 Growbags. Apply the CaNO3 in small cycles in order to avoid unwanted drainage.

Wait 48 hours and rinse the Growbags with clean water until the drainage EC is similar to your water EC.

After Planting

EC and PH Value

After planting, EC of irrigation water is determent by base water EC and the nutrition requirements of the plants.

Tomatoes are relatively tolerant to EC and pH values but it is highly recommended to monitor pH and EC values of irrigation water and drainage water. Make sure that the Values stay within the desired range.  

Monitoring the difference of EC and pH in irrigation water and drainage is critical for good management and achieving the targeted yield.

Drainage Water

Ocassionally analyzing drainage water for nutrients concentration and comparing it to the level of nutrients in the irrigation water will be very helpful for crop management.

During all stages of growth, the fertigation solution must contain all nutrients. 

Today’s technology offers advanced tools for crop management. Installing methods such as monitring the moisture continuous change in the tomato grow bags and weight continuous change, will enable better crop management.
