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 infield 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 make 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.c

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 its ratio between air and water. Although the Cocopeat has adequate water capacity it also maintains a balanced air capacity as well. Pelemix’s pressing technology guarantees that the distribution of the different segmentations inside the grow bag will be equal. By doing so, Pelemix creates a uniform grow bag that allows air and water to be distributed equally in 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 again, Pelemix’s pressing technology guarantees that the distribution of the two Coir types, inside the tomato grow bag, will be uniform. 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 having a cold winter and hot summer. It is perfect for growers who are interested in applying 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 growbags and growing structure (Greenhouse, Net-house etc.).

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

Expention of Growbags

Expand the Growbags with cycles of short irrigations. 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). 

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

Arrow Drippers and Draining Holes

Arrow drippers are very recommend but a dripline is also possible. 

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

Pelemix Grow Bags come with a Planting and drainage holes in accordance to the client’s request. 

Calcium Nitrate treatment

Calcium Nitrate treatment- in order to improve nutrients balance at planting time, 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 its 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 in wanted 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

Analyzing drainage water for nutrients concentration occasionally, and comparing to irrigation nutrients level, will be very helpful for crop management.

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

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