What?makes?it?good?for?hydroponics?
?The?properties?of?LECA?are?highly?attractive?to?hydroponic?gardeners;?it?is?inert,?can?be?used?multiple?times?and?is?also?pH?neutral.?As?it?is?made?up?of?hard,?porous?pellets?it?also?enhances?the?levels?of?oxygen?the?plants ?are?exposed?to?and?drains?well?in?hydroponics?systems.
?
LECA?also?provides?a?number?of?distinct?benefits:
?
?
- The?high?oxygen?levels?and?improved?drainage?provided?by?LECA?can?help?to?prevent?root?rot.
- It?helps?to?conserve?water?and?is?ideal?for?hydroponics?systems?due?to?the?fact?that?it?drains?quickly.
- Gives?roots?a?solid?foothold?so?that?they?can?become?secure.
- It?can?be?recycled?multiple?times?making?it?very?cost?effective.
- Can?be?easily?sterilised?if?transferring?plants?or?starting?a?new?project?with?existing?materials.
- The?main?disadvantage?is?that?LECA?doesn’t?hold?moisture?as?well?as?more?absorbent?mediums,?such?as?coco-coir,?although?this?can?be?combated?by?combining?it?with?other?mediums ?
- We?are?one?of?the?biggest?manufacturers?in?China,
- ?Advanced?technology?and?facilities,?good?quality?contral,?different?grades?for?different?applicaiton?fields.
- ?OEM?service?to?lots?of?big?international?companies.
- ?More?than 10 years?experiecne?in?different?industries.
- ?More?than?20?engineers?for?product?research?and?after-sale?service.
- More?than?100?thousand?tons?production?per?one?year.
