hi there,
im 100 percent sure we can grow lettuce in phil..coz we hv lots in our farm.i came from davao and i hv a farm 80 miles from downtown area which the climate is same as baguio in manila.we hv loads in there and so cheap,even lots are sold along the way going to cagayan via bukidnon.the price just usually 10 pesos per kilo sometimes 5 pesos only..we even hv brocolli and cauliflower grown in there...
