Asked the wife which wanted and she said steel,, Shopped about from KC to Surin with some excellent help. Best price that was found was Global House and that was with delivery. Soooo bought SWMBO the equivalent of about 1 1/2 baht of GOLD. She tells me there is enough steel to build 2 greenhouses 25m long x 6m wide x 2m tall. Supervisor and Leo Planting rice. Second crop.
