I am working in phnom penh and I have to build a green wall about three metres wide and two and half metres high on the end of a building.
I have had many years experience with growing the other and I have found two hydroponic suppliers here. They have a lot of stuff but everyone grows in small pots in PVC pipes, an NFT system.
I will have about 350 small pots in a frame each with a dripper and a resevoir below with a pump and a timer for recycling.Just one problem here- no drippers? Bunnings have them at $28 for 50, cheap. Anyone know what they cost in Bangkok, I may have to come over and buy them.
