Coir FAQs

Production

Do you provide technical support?

Our technology partners in Holland and France provide advice and expertise to growers when required throughout the season. We strive to provide excellent customer service and support.

What is the water holding capacity of coir?

Classic – 8 litres/kg of dry material
Profit – 6 litres/kg of dry material

Can the Gro Bags be pre-cut with holes?

Yes, we can pre-cut the Gro Bags at the production factory with plant holes, drain slits and a small hole drilled in the coir for your dripper. This makes installation of the Gro Bags very easy and quick.

What is the lifespan of coir?

Trials have shown that coir will retain its structure and not break down for the duration of the plants growth cycle. In fact, the Profit and Crush materials have been used for several years by a grower without replacing Gro Bags.

I have been told Crush Coir is a generative growing substrate.

This is true due to a high air holding capacity, Crush coir gives you excellent drainage which allows you to steer your crop easily.

I have heard coir can be high in salts.

Coconuts are a fruit and therefore naturally high in sodium and potassium. Besgrow has a range of products with different EC levels which can be recommended to you dependent on the type of plant you are growing.

Which part of the coconut is used to produce Besgrow Coir?

Daltons Coir grades are produced from the pith and fibres of the coconut husk. Using an age old process the pith is extracted from the husk, creating a material with only minimal amount of fibres. This is used to create our finer grades, Precision and Classic. The long fibres are then used to create our textile products, Weed Mat and Erosion Control. Coarser grades are produced from the whole husk that is chopped and crushed to form large chips. This material is used for our grades, Profit and Crush.

Where does Daltons Coir come from?

Daltons Coir comes from our processing facility in Sri Lanka

Usage

What is the easiest way to hydrate Coir?

Bulk – For maximum yield of a bale of coir immerse the bales in water at a rate of 8 litres per kilo. This will hydrate in a very short time, however, allow time for the bale to completely absorb the water. Once hydrated drain off the surplus water.

Gro Bag – Lay out the plastic floor covering and position Gro Bags as desired. Poke dripper through plastic to hydrate the coir slab with recommended solution. Once hydrated, cut holes for plants and drainage slits. To allow plenty of drainage make vertical cuts (2-3cm) on each side of the slab by running the knife up from the base. Place your cube/bottomless pot with plant on top of slab. Place dripper into the cube/ bottomless pot.

REMEMBER: Never let Gro Bags sit in water as they act like a sponge and will take the water back into the slab.Make sure if your Gro Bag is on an angle that the drainage slits are cut at the lowest point, preferably not under the plants or where the dripper enters the slab. The best way to measure water content is by using up a weigh scale. Gro Bags must lose at least 1kg of weight per night before commencing your water schedule the next day

I have heard mixing coir into potting mixes gives better root and foliage development.

Yes coir is great in a potting mix as it increases water holding and aeration in the mix. Coir holds on to the fertiliser to make available for the plant.
