Ezimpahleni ezidinga ukusebenza okuphezulu okungangeni manzi, kunconywa ukuthi ukhethe indwangu eboshiwe ye-PVC, indwangu yokukhuhla ummese noma indwangu yenayiloni engangeni manzi ekhiqizwe i-Tongtuo tarpaulin.
Ihlukaniswa ngokusetshenziswa kukaseyili: useyili ongangenwa yimvula egcekeni lomthwalo, useyili wemoto, useyili wetende ongangeni manzi, indawo yokugcina amanzi, ichibi lezinhlanzi ze-tarp; ikhethini le-tarp roll yepulazi lezingulube nepulazi lezimvu; itiyela lasolwandle; utiyela wefekthri nowamayini; imishini yokuvimbela amanzi ikhava yetarpaulin; itende likaseyili elingangeni manzi elihoshayo, ipayipi likaseyili; indwangu ezungezile esobala yamatafula okudla; useyili ongangenisi uthuli umhlobiso; vala useyili
Lapho amaloli ethuthwa, izimpahla kudingeka zimbozwe ngoseyili ukuze zivikeleke elangeni nasemvuleni. Njengamanje, kunezinhlobo eziningi zoseyili emakethe, okuhlanganisa indwangu enobufakazi obuthathu, indwangu ye-Oxford, indwangu yokukhuhla ummese, iseyili ye-pvc, indwangu ye-silicone, njll.
Ifilimu ye-multi-span greenhouse ingenye yezinto ezisetshenziswa kakhulu zokumboza i-greenhouse ekukhiqizweni kwezolimo, futhi ukusetshenziswa kwayo kwansuku zonke kusuka kumakhothamo endabuko angaphansi komhlaba, izindawo zokugcina izithombo zokukhanya kwelanga, izindawo zokugcina izithombo ezinezinhlangothi ezimbili, izindawo zokugcina izithombo zefilimu enama-span amaningi, kanye nezindawo zokugcina izithombo zesikhunta.
Indlela yokukhetha ifilimu ye-greenhouse ye-multi-span ifilimu yokugcina ifilimu ingenye yezindaba ezibalulekile abalimi endaweni yokushisa ye-off-season abakhathazeke ngayo.
I-tarpaulin (noma indwangu engangenwa ngamanzi) inamandla amakhulu, ukuqina okuhle nokuthamba okungangeni manzi. Ihlala isetshenziswa njengendwangu (uwoyela canvas), i-polyester eboshwe nge-polyurethane noma eyenziwe ngeplastiki ye-polyethylene.
