Good Day,
Saan po nakakabili nang square pvc pipes? Yung pedeng gamitin as channel sa NFT System ng Hydroponics.
Instead na round pipes, rectangular or square daw po ang maganda kasi flat yung surface, so mas efficient
ang flow ng nutrient solution. Ideally yung UV rated para kahit bilad sa araw, hindi sya mag ka-crack.
How much kaya yun? Any ideas? Makati or San Mateo Rizal area po ako.
